Data scraping tool for non-coding journalists launches

A tool which helps non-coding journalists scrape data from websites has launched in public beta today.

Import.io lets you extract data from any website into a spreadsheet simply by mousing over a few rows of information.

Until now import.io, which we reported on back in April, has been available in private developer preview and has been Windows only. It is now also available for Mac and is open to all.

Although import.io plans to charge for some services at a later date, there will always be a free option.

The London-based start-up is trying to solve the problem of the fact that there is "lots of data on the web, but it's difficult to get at", Andrew Fogg, founder of import.io, said in a webinar last week.

Those with the know-how can write a scraper or use an API to get at data, Fogg said. "But imagine if you could turn any website into a spreadsheet or API."

Uses for journalists

Journalists can find stories in data. For example, if I wanted to do a story on the type of journalism jobs being advertised and the salaries offered, I could research this by looking at various websites which advertise journalism jobs.

If I were to gather the data from four different jobs boards and enter the information manually into a spreadsheet it would take would take hours if not days; if I were to write a screen scraper for each of the sites it would require knowledge and would probably take a couple of hours. Using import.io I can create a single dataset from multiple sources in a few minutes.

I can then search and sort the dataset and find out different facts, such as how many unpaid internships are advertised, or how many editors are currently being sought.

How it works

When you download the import.io application you see a web browser. This browser allows you to enter a URL for any site you want to scrape data from.

To take the example of the jobs board, this is structured data, with the job role, description and salaries displayed.

The first step is to set up 'connectors' and to do this you need to teach the system where the data is on the page. This is done by hitting a 'record' button on the right of the browser window and mousing over a few examples, in this case advertised jobs. You then click 'train rows'.

It takes between two and five examples to teach import.io where all of the rows are, Fogg explained in the webinar.

The next step is to declare the type of data and add column names. For example there may be columns for 'job title', 'job description' and 'salary'. Data is then extracted into the table below the browser window.

Data from different websites can then be "mixed" into a single searchable database.

In the example used in the webinar, Fogg demonstrated how import.io could take data relating to rucksacks for sale on a shopping website. The tool can learn the "extraction pattern", Fogg explained, and apply that to to another product. So rather than mousing over the different rows of sleeping bags advertised, for example, import.io was automatically able to detect where the price and product details were on the page as it had learnt the structure from how the rucksacks were organised. The really smart bit is that the data from all products can then be automatically scraped and pulled into the spreadsheet. You can then search 'shoes' and find the data has already been pulled into your database.

When a site changes its code a screen scraper would become ineffective. Import.io has a "resilience to change", Fogg said. It runs tests twice a day and users get notified of any changes and can retrain a connector.

It is worth noting that a site that has been scraped will be able to detect that import.io has extracted the data as it will appear in the source site's web logs.

Case studies

A few organisations have already used import.io for data extraction. Fogg outlined three.

    British Red Cross

The British Red Cross wanted to create an iPhone app with data from the NHS Choices website. The NHS wanted the charity to use the data but the health site does not have an API.

By using import.io, data was scraped from the NHS site. The app is now in the iTunes store and users can use it to enter a postcode to find hospital information based on the data from the NHS site.

"It allowed them to build an API for a website where there wasn't one," Fogg said.

    Hewlett Packard

Fogg explained that Hewlett Packard wanted to monitor the prices of its laptops on retailers' websites.

They used import.io to scrape the data from the various sites and were able monitor the prices at which the laptops were being sold in real-time.

    Recruitment site

A US recruitment firm wanted to set up a system so that when any job vacancy appeared on a competitor's website, they could extract the details and push that into their Salesforce software. The initial solution was to write scrapers, Fogg said, but this was costly and in the end they gave up. Instead they used import.io to scrape the sites and collate the data.

ScraperWiki lets anyone scrape Twitter data without coding

The Obama administration’s open data mandate announced on Thursday was made all the better by the unveiling of the new ScraperWiki service on Friday. If you’re not familiar with ScraperWiki, it’s a web-scraping service that has been around for a while but has primarily focused on users with some coding chops or data journalists willing to pay to have someone scrape data sets for them. Its new service, though, currently in beta, also makes it possible for anyone to scrape Twitter to create a custom data set without having to write a single line of code.

Taken alone, ScraperWiki isn’t that big of a deal, but it’s part of a huge revolution that has been called the democratization of data. More data is becoming available all the time — whether from the government, corportations or even our own lives — only it’s not of much use unless you’re able to do something with it. ScraperWiki is now one of a growing list of tools dedicated to helping everyone, not just expert data analysts or coders, analyze — and, in its case, generate — the data that matters to them.

After noticing a particularly large numbers of tweets in my stream about flight delays yesterday, I thought I’d test out ScraperWiki’s new Twitter search function by gathering a bunch of tweets directed to @United. The results — from 1,697 tweets dating back to May 3 — are pretty fun to play with, if not that surprising. (Also, I have no idea how far back the tweet search will go or how long it will take using the free account, which is limited to 30 minutes of compute time a day. I just stopped at some point so I could start digging in.)

First things first, I ran my query. Here’s what the data looks like viewed in a table in the ScraperWiki app.

Next, it’s a matter of analyzing it. ScraperWiki lets you view it in a table (like above), export it to Excel or query it using SQL, and will also summarize it for you. This being Twitter data, the natural thing to do seemed to be analyzing it for sentiment. One simple way to do this right inside the ScraperWiki table is to search for a particular term that might suggest joy or anger. I chose a certain four-letter word that begins with f.

Surprisingly, I only found eight instances. Here’s my favorite: “Your Customer Service is better than a hooker. I paid a bunch of money and you’re still…” (You probably get the idea.)

But if you read my “data for dummies” post from January, you know that we mere mortals have tools at our disposal for dealing with text data in a more refined way. IBM’s Many Eyes service won’t let me score tweets for sentiment, but I can get a pretty good idea overall by looking at how words are used. For this job, though, a simple word cloud won’t work, even after filtering out common words, @united and other obvious terms. Think of how “thanks” can be used sarcastically and you can see why.

Using the customized word tree, you can see that “thanks” sometimes means “thanks.” Other times, not so much. I know it’s easy to dwell on the negative, but consider this: “worst” had 28 hits while “best” had 15. One of those was referring to Tito’s vodka and at least three were referring to skyline views. (Click here to access it and search by whatever word you want.)

Here’s a phrase net filtering the results by phrases where the word “for” connects two words.

Anyhow, this was just a fast, simple and fairly crude example of what ScraperWiki now allows users to do, and how that resulting data can be combined with other tools to analyze and visualize it. Obviously, it’s more powerful if you can code, but new tools are supposedly on the way (remember, this is just a beta version) that should make it easier to scrape data from even more sources.

In the long term, though, services like ScraperWiki should become a lot more valuable as tools for helping us generate and analyze data rather than just believe what we’re told. Want to improve your small business, put your life in context or perhaps just write the best book report your teacher has ever seen? It’s getting easier every day.

A Guide to Web Scraping Tools

This post is ghost written by one of my bloggers, I outsource 95% of my life.  The author’s views below are entirely his or her own and may not reflect the views of  Gareth James

aka SEO Doctor

Web Scrapers are tools designed to extract / gather data in a website via crawling engine usually made in Java, Python, Ruby and other programming languages.Web Scrapers

are also called as Web Data Extractor, Data Harvester , Crawler and so on which most of them are web-based or can be installed in local desktops.

Its main purpose is to enable webmasters, bloggers, journalist and virtual assistants to harvest data from a certain website whether text, numbers, contact details and images

in a structured way which cannot be done easily thru manual copy and paste method. Typically, it transforms the unstructured data on the web, from HTML format into a

structured data stored in a local database or spreadsheet or automates web human browsing.

What is data scraping and how can I stop it?

Data scraping (also called web scraping) is the process of extracting information from websites. Data scraping focuses on transforming unstructured website content (usually HTML) into structured data which can be stored in a database or spreadsheet.

The way data is scraped from a website is similar to that used by search bots – human web browsing is simulated by using programs (bots) which extract (scrape) the data from a website.

Unfortunately, there is no efficient way to fully protect your website from data scraping. This is so because data scraping programs (also called data scrapers or web scrapers) obtain the same information as your regular web visitors.

Even if you block the IP address of a data scraper, this will not prevent it from accessing your website. Most data scraping bots use large IP address pools and automatically switch the IP address in case one IP gets blocked. And if you block too many IPs, you will most probably block many of your legitimate visitors.

One of the best ways to protect globally accessible data on a website is through copyright protection. This way you can legally protect the intellectual ownership of your website content.

Another way to protect your site content is to password protect it. This way your website data will be available only to people who can authenticate with the correct username and password.

What you need to know about web scraping: How to understand, identify, and sometimes stop

This is a gust article by Rami Essaid, co-founder and CEO of Distil Networks.

Here’s the thing about web scraping in the travel industry: everyone knows it exists but few know the details.

Details like how does web scraping happen and how will I know? Is web scraping just part of doing business online, or can it be stopped? And lastly, if web scraping can be stopped, should it always be stopped?

These questions and the challenge of web scraping are relevant to every player in the travel industry. Travel suppliers, OTAs and meta search sites are all being scraped. We have the data to prove it; over 30% of travel industry website visitors are web scrapers.

Google Analytics, and most other analytics tools do not automatically remove web scraper traffic, also called “bot” traffic, from your reports – so how would you know this non-human and potentially harmful traffic exists? You have to look for it.

This is a good time to note that I am CEO of a bot-blocking company called Distil Networks, and we serve the travel industry as well as digital publishers and eCommerce sites to protect against web scraping and data theft – we’re on a mission to make the web more secure.

So I am admittedly biased, but will do my best to provide an educational account of what we’ve learned to be true about web scraping in travel – and why this is an issue every travel company should at the very least be knowledgeable about.

Overall, I see an alarming lack of awareness around the prevalence of web scraping and bots in travel, and I see confusion around what to do about it. As we talk this through I’ll explain what these “bots” are, how to find them and how to manage them to better protect and leverage your travel business.

What are bots, web scrapers and site indexers? Which are good and which are bad?

The jargon around web scraping is confusing – bots, web scrapers, data extractors, price scrapers, site indexers and more – what’s the difference? Allow me to quickly clarify.

–> Bots: This is a general term that refers to non-human traffic, or robot traffic that is computer generated. Bots are essentially a line of code or a program that is created to perform specific tasks on a large scale.  Bots can include web scrapers, site indexers and fraud bots. Bots can be good or bad.

–> Web Scraper: (web harvesting or web data extraction) is a computer software technique of extracting information from websites (source, Wikipedia). Web scrapers are usually bad.

If your travel website is being scraped, it is most likely your competitors are collecting competitive intelligence on your prices. Some companies are even built to scrape and report on competitive price as a service. This is difficult to prove, but based on a recent Distil Networks study, prices seem to be main target.You can see more details of the study and infographic here.

One case study is Ryanair. They have been particularly unhappy about web scraping and won a lawsuit against a German company in 2008, incorporated Captcha in 2011 to stop new scrapers, and when Captcha wasn’t totally effective and Cheaptickets was still scraping, they took to the courts once again.

So Ryanair is doing what seems to be a consistent job of fending off web scrapers – at least after the scraping is performed. Unfortunately, the amount of time and energy that goes into identifying and stopping web scraping after the fact is very high, and usually this means the damage has been done.

This type of web scraping is bad because:

    Your competition is likely collecting your price data for competitive intelligence.
    Other travel companies are collecting your flights for resale without your consent.
    Identifying this type of web scraping requires a lot of time and energy, and stopping them generally requires a lot more.

Web scrapers are sometimes good

Sometimes a web scraper is a potential partner in disguise.

Meta search sites like Hipmunk sometimes get their start by scraping travel site data. Once they have enough data and enough traffic to be valuable they go to suppliers and OTAs with a partnership agreement. I’m naming Hipmunk because the Company is one of the few to fess up to site scraping, and one of the few who claim to have quickly stopped scraping when asked.

I’d wager that Hipmunk and others use(d) web scraping because it’s easy, and getting a decision maker at a major travel supplier on the phone is not easy, and finding legitimate channels to acquire supplier data is most definitely not easy.

I’m not saying you should allow this type of site scraping – you shouldn’t. But you should acknowledge the opportunity and create a proper channel for data sharing. And when you send your cease and desist notices to tell scrapers to stop their dirty work, also consider including a note for potential partners and indicate proper channels to request data access.

–> Site Indexer: Good.

Google, Bing and other search sites send site indexer bots all over the web to scour and prioritize content. You want to ensure your strategy includes site indexer access. Bing has long indexed travel suppliers and provided inventory links directly in search results, and recently Google has followed suit.

–> Fraud Bot: Always bad.

Fraud bots look for vulnerabilities and take advantage of your systems; these are the pesky and expensive hackers that game websites by falsely filling in forms, clicking ads, and looking for other vulnerabilities on your site. Reviews sections are a common attack vector for these types of bots.

How to identify and block bad bots and web scrapers

Now that you know the difference between good and bad web scrapers and bots, how do you identify them and how do you stop the bad ones? The first thing to do is incorporate bot-identification into your website security program. There are a number of ways to do this.

In-house

When building an in house solution, it is important to understand that fighting off bots is an arms race. Every day web scraping technology evolves and new bots are written. To have an effective solution, you need a dynamic strategy that is always adapting.

When considering in-house solutions, here are a few common tactics:

    CAPTCHAs – Completely Automated Public Turing Tests to Tell Computers and Humans Apart (CAPTCHA), exist to ensure that user input has not been generated by a computer. This has been the most common method deployed because it is simple to integrate and can be effective, at least at first. The problem is that Captcha’s can be beaten with a little workand more importantly, they are a nuisance to end usersthat can lead to a loss of business.

    Rate Limiting- Advanced scraping utilities are very adept at mimicking normal browsing behavior but most hastily written scripts are not. Bots will follow links and make web requests at a much more frequent, and consistent, rate than normal human users. Limiting IP’s that make several requests per second would be able to catch basic bot behavior.
    IP Blacklists - Subscribing to lists of known botnets & anonymous proxies and uploading them to your firewall access control list will give you a baseline of protection. A good number of scrapers employ botnets and Tor nodes to hide their true location and identity. Always maintain an active blacklist that contains the IP addresses of known scrapers and botnets as well as Tor nodes.

    Add-on Modules – Many companies already own hardware that offers some layer of security. Now, many of those hardware providers are also offering additional modules to try and combat bot attacks. As many companies move more of their services off premise, leveraging cloud hosting and CDN providers, the market share for this type of solution is shrinking.

    It is also important to note that these types of solutions are a good baseline but should not be expected to stop all bots. After all, this is not the core competency of the hardware you are buying, but a mere plugin.

Some example providers are:

    Impreva SecureSphere- Imperva offers Web Application Firewalls, or WAF’s. This is an appliance that applies a set of rules to an HTTP connection. Generally, these rules cover common attacks such as Cross-site Scripting (XSS) and SQL Injection. By customizing the rules to your application, many attacks can be identified and blocked. The effort to perform this customization can be significant and needs to be maintained as the application is modified.

    F5 – ASM – F5 offers many modules on their BigIP load balancers, one of which is the ASM. This module adds WAF functionality directly into the load balancer. Additionally, F5 has added policy-based web application security protection.

Software-as-a-service

There are website security software options that include, and sometimes specialize in web scraping protection. This type of solution, from my perspective, is the most effective path.

The SaaS model allows someone else to manage the problem for you and respond with more efficiency even as new threats evolve.  Again, I’m admittedly biased as I co-founded Distil Networks.

When shopping for a SaaS solution to protect against web scraping, you should consider some of the following factors:

    Does the provider update new threats and rules in real time?
    How does the solution block suspected non-human visitors?
    Which types of proactive blocking techniques, such as code injections, does the provider deploy?
    Which of the reactive techniques, such as rate limiting, are used?
    Does the solution look at all of your traffic or a snapshot?
    Can the solution block bots before they reach your infrastructure – and your data?
    What kind of latency does this solution introduce?

I hope you now have a clearer understanding of web scraping and why it has become so prevalent in travel, and even more important, what you should do to protect and leverage these occurrences.

Understanding Web Scraping

It is evident that the invention of the internet is one of the greatest inventions of life. This is so because it allows quick recovery of information from large databases. Though the internet has its own negative aspects, its advantages outweigh the demerits f using it. It is therefore the objective of every researcher to understand the concept of web scraping and learn the basics of collecting accurate data from the internet. The following are some of the skills researchers need to know and keep them abreast of:

Understanding File Extensions in Web Scraping

In web scraping the first step to know is file extensions. For instance a site ending with dot-com is either a sales or commercial site. With the involvement of sales activity in such a website, there is a possibility that the data contained therein is inaccurate. Sites that may be ending with dot-gov are sites owned by various governments. The information found on such websites is accurate since they are reviewed by professionals regularly. Sites ending with dot-org are sites owned by non-governmental organizations that are not after making profit. There is a greater probability that the information contained is not accurate. Sites ending with dot-edu are owned by educational institutions. The information found on such sites is sourced by professionals and is of high quality. In case you have no understanding concerning a particular website it is important that get more information from expert data mining services.

Search Engine Limitations in Web Scraping

After understanding the file extensions, the next step is to understand search engine limitations applied to web scraping. These include process such as file extension, filtering or any other parameters. The following are some of the restrictions that need to typed after your search term: for instance if you key in â€Å“finance” and then click â€Å“search” all sites will be listed from the dot-com directory that contain the word finance on its website. If you key in â€Å“finance site.gov,” of course with the quotation marks, only the government sites that have the word finance will be listed. The same applies to other sites with different file extensions.

Advanced Parameters in Web Scraping

When performing web scraping it is important to understand more skills beyond the file extension. Therefore there is a need to understand particular search terms. For instance if you key in â€Å“software company in India” without the quotation marks, the search engines will display thousands of websites having â€Å“software”, â€Å“company” and India in their search terms. If you key in â€Å“Software Company in India” with the quotation marks, the search engines will only display sites that contain the exact phrase â€Å“software company in India” within their text.

This article forms the basis of web scraping. Collection of data needs to be carried out by experts and high quality tools. This is to ensure that the quality and accuracy of the data scraped is of high standards. The information extracted from that data has wide applications in business operations including decision making and predictive analytics.

Web Scraping and Financial Matters

Many marketers value the process of harvesting data on the financial sector. They are also conversant with the challenges concerning the collection and processing of the data. Web scraping techniques and technologies are used for tracking and recognizing patterns that are found within the data. This is quite useful to businesses as it shifts through the layers of data, remove unrelated data and only leave the data that has meaningful relationships. This enables companies anticipate rather than just reacting to the customer and financial needs. Web scraping in combination with other complementary technologies and sound business processes, it can be used in reinforcing and redefining financial analysis.

Objectives of web scraping

The following are some of the web scraping services objectives that are covered in this article:

1. Discus show the customization of data and data mining tools may be developed for financial data analysis.

2. What is the usage pattern, in terms of purpose and the categories for the need for financial analysis?

3. Is the development of a tool for financial analysis through web scraping techniques possible?

Web scraping can be regarded as the procedure of extracting or harvesting knowledge for the large quantities of data. It is also known as Knowledge Discovery in Database (KDD). This implies that web scraping involves data collection, data management, database creation and the analysis of data and its understanding.

The following are some of the steps that are involved in web scraping service:

1. Data cleaning. This is the process of removing nose and the inconsistent data. This process is important as it only ensures that only important data should be integrated. This process saves time that will be consumed in the next processes.

Data Extraction,Web Screen Scraping Tool,Mozenda Scraper

Web Scraping

Web scraping, also known as Web data extraction or Web harvesting, is a software method of extracting data from websites. Web scraping is closely related and similar to Web indexing, which indexes Web content. Web indexing is the method used by most search engines. The difference with Web scraping is that it focuses more on the translation of unstructured content on the Web, characteristically in rich text format like that of HTML, into controlled data that can be analyzed stored and in a spreadsheet or database. Web scraping also makes Web browsing more efficient and productive for users. For example, Web scraping automates weather data monitoring, online price comparison, and website change recognition and data integration.

This clever method that uses specially coded software programs is also used by public agencies. Government operations and Law enforcement authorities use data scrape methods to develop information files useful against crime and evaluation of criminal behaviors. Medical industry researchers get the benefit and use of Web scraping to gather up data and analyze statistics concerning diseases such as AIDS and the most recent strain of influenza like the recent swine flu H1N1 epidemic.

Data scraping is an automatic task performed by a software program that extracts data output from another program, one that is more individual friendly. Data scraping is a helpful device for programmers who have to generate a line through a legacy system when it is no longer reachable with up to date hardware. The data generated with the use of data scraping takes information from something that was planned for use by an end user.

One of the top providers of Web scraping software, Mozenda, is a Software as a Service company that provides many kinds of users the ability to affordably and simply extract and administer web data. Using Mozenda, individuals will be able to set up agents that regularly extract data then store this data and finally publish the data to numerous locations. Once data is in the Mozenda system, individuals may format and repurpose data and use it in other applications or just use it as intelligence. All data in the Mozenda system is safe and sound and is hosted in a class A data warehouses and may be accessed by users over the internet safely through the Mozenda Web Console.

One other comparative software is called the Djuggler. The Djuggler is used for creating web scrapers and harvesting competitive intelligence and marketing data sought out on the web. With Dijuggles, scripts from a Web scraper may be stored in a format ready for quick use. The adaptable actions supported by the Djuggler software allows for data extraction from all kinds of webpages including dynamic AJAX, pages tucked behind a login, complicated unstructured HTML pages, and much more.

Ultimate Scraping Three Common Methods For Web Data Extraction

So what's the best way to data extraction? It really is dependent upon what your needs are, and what resources you have you can use. Here are some of the pros and cons of the various options, as well as suggestions on once you might use each an individual:

Raw regular expressions in addition to code

<em>Advantages: </em>

- If you're already informed about regular expressions and some form of programming language, this may be a quick solution.

- Regular expressions allow for a fair amount of "fuzziness" inside the matching such that minor changes towards the content won't break them all.

- You likely don't should try to learn any new languages or perhaps tools (again, assuming you're already informed about regular expressions and a new programming language).

- Regular expressions are supported in most of modern programming languages. Daylights, even VBScript has a daily expression engine. It's also nice for the reason that various regular expression implementations don't vary too significantly within their syntax.

<em>Disadvantages: </em>

- They are definitely complex for those that don't have plenty of experience with them. Figuring out regular expressions isn't want going from Perl for you to Java. It's more enjoy going from Perl to make sure you XSLT, where you really have to wrap your mind around an entirely different way of viewing the condition.

- They're often confusing to evaluate. Take a look through a number of the regular expressions people have manufactured to match something as simple as an email address and you'll see what i mean.

- If the content you're endeavoring to match changes (e. h., they change the internet page by adding a brand-new "font" tag) you'll likely must update your regular expressions to take into account the change.

- The data discovery component to the process (traversing various web pages to go to the page containing the data you want) will still should be handled, and can get fairly complex region deal with cookies and additionally such.

<em>When to make use approach: </em> You'll most in all likelihood use straight regular expressions in screen-scraping when you experience a small job you intend to get done quickly. Especially if you now know regular expressions, there's no sense in stepping into other tools if all you decide to do is pull some news headlines off a site.

Ontologies as well as artificial intelligence

<em>Advantages: </em>

- You create the software once and it can awfully extract the data from any page while in the content domain you're looking for.

- The data model is mostly built in. For case in point, if you're extracting data files about cars from online sites the extraction engine now knows what the help to make, model, and price are generally, so it can easily map it to existing data structures (e. gary the gadget guy., insert the data throughout the correct locations in ones own database).

- There is certainly relatively little long-term preservation required. As web sites change you likely might want to do very little to all your extraction engine as a way to account for the transformations.

<em>Disadvantages: </em>

- It's relatively complex for making and work with this engine. The level of expertise needed to even understand an removal engine that uses man-made intelligence and ontologies is noticeably higher than what must deal with regular words and phrases.

Challenges in Effective Web Data Mining

Data collection and web data mining are critical processes for many companies and the marketing companies today. The techniques usually used include search engines, topic-based searches and directories. Web data mining is necessary for any business that wants to create data warehouses by harvesting data from the internet. This is so because high-quality and intelligent information may not be harvested from the internet easily. Such information is critical as it enables you to get desired results and the business intelligence in demand.

Keyword-based searches are important in marketing of company products. They are usually affected by the following factors:
̢ۢ Irrelevant pages. The use of common and general keywords on the search engines yields millions of web pages. Some of thesepages may be irrelevant and may not be of help to the user.

̢ۢ Ambiguous results.This is usually caused by multi-variant or similar keyword semantics. A name would be an animal, movie or even a sport accessory. This results in web pages that are different what you are actually searching for.

̢ۢ Possibility of missing some web pages.There is a great possibility of missing the most relevant information that is contained on web pages that are not indexed on a given keyword.

One of the factors that prohibit the usage of web data mining is the effectiveness of search engine crawlers. This is widely evidenced by lack of access of the entire web due to search engine crawlers and bot.This can be attributed partly tobandwidth limitations. It is important to understand that there are thousands of databases on the internet that can deliver well-maintained information, high quality and are not easily accessed by crawlers.

In web data mining it is important to understand that majority of search engines have limited choices or alternatives for keyword query combination. For instance, yahoo and Google offer option like phrase and even the exact matches that may limit even the search results. It is usually demands more efforts and even time and thereby get the most important and relevant information.The human behavior and the alternatives usually change of time.This therefore implies that web pages need to be updated frequently and there by reflect on the emerging trends. It is important to realize that there is a limited space for web data mining. This is so because the information that currently exists is heavily relied on keyword-based indices. This does not apply for the real data.

It is important to realize that web data mining is an important tool for any business. It is therefore important to embrace this technology to solve data crisis problems. There are several limitations and many challenges which may have resulted in the quest of effectively and efficiently in rediscovering the use of web resources. However, irrespective of the challenges of web data mining, this technology is an effective tool that can be employed in many technological and scientific fields. It is therefore paramount to embrace this technology and use it fully in order to realize your corporate goals.

Microsys A1 Website Scraper Review

The A1 scraper by Microsys is a program that is mainly used to scrape websites to extract data in large quantities for later use in webservices. The scraper works to extract text, URLs etc., using multiple Regexes and saving the output into a CSV file. This tool is can be compared with other web harvesting and web scraping services.
How it works
This scraper program works as follows:
Scan mode

    Go to the ScanWebsite tab and enter the site’s URL into the Path subtab.
    Press the ‘Start scan‘ button to cause the crawler to find text, links and other data on this website and cache them.

Important: URLs that you scrape data from have to pass filters defined in both analysis filters and output filters. The defining of those filters can be set at the Analysis filters and Output filters subtabs respectively. They must be set at the website analysis stage (mode).
Extract mode

    Go to the Scraper Options tab
    Enter the Regex(es) into the Regex input area.
    Define the name and path of the output CSV file.
    The scraper automatically finds and extracts the data according to Regex patterns.

The result will be stored in one CSV file for all the given URLs.

There is a need to mention that the set of regular expressions will be run against all the pages scraped.
Some more scraper features

Using the scraper as a website crawler also affords:

    URL filtering.
    Adjustment of the speed of crawling according to service needs rather than server load.

If  you need to extract data from a complex website, just disable Easy mode: out press the  button. A1 Scraper’s full tutorial is available here.
Conclusion

The A1 Scraper is good for mass gathering of URLs, text, etc., with multiple conditions set. However this scraping tool is designed for using only Regex expressions, which can increase the parsing process time greatly.

Visual Web Ripper: Using External Input Data Sources

Sometimes it is necessary to use external data sources to provide parameters for the scraping process. For example, you have a database with a bunch of ASINs and you need to scrape all product information for each one of them. As far as Visual Web Ripper is concerned, an input data source can be used to provide a list of input values to a data extraction project. A data extraction project will be run once for each row of input values.

An input data source is normally used in one of these scenarios:

    To provide a list of input values for a web form
    To provide a list of start URLs
    To provide input values for Fixed Value elements
    To provide input values for scripts

Visual Web Ripper supports the following input data sources:

    SQL Server Database
    MySQL Database
    OleDB Database
    CSV File
    Script (A script can be used to provide data from almost any data source)

To see it in action you can download a sample project that uses an input CSV file with Amazon ASIN codes to generate Amazon start URLs and extract some product data. Place both the project file and the input CSV file in the default Visual Web Ripper project folder (My Documents\Visual Web Ripper\Projects).

For further information please look at the manual topic, explaining how to use an input data source to generate start URLs.

Using External Input Data in Off-the-shelf Web Scrapers

There is a question I’ve wanted to shed some light upon for a long time already: “What if I need to scrape several URL’s based on data in some external database?“.

For example, recently one of our visitors asked a very good question (thanks, Ed):

    “I have a large list of amazon.com asin. I would like to scrape 10 or so fields for each asin. Is there any web scraping software available that can read each asin from a database and form the destination url to be scraped like http://www.amazon.com/gp/product/{asin} and scrape the data?”

This question impelled me to investigate this matter. I contacted several web scraper developers, and they kindly provided me with detailed answers that allowed me to bring the following summary to your attention:
Visual Web Ripper

An input data source can be used to provide a list of input values to a data extraction project. A data extraction project will be run once for each row of input values. You can find the additional information here.
Web Content Extractor

You can use the -at”filename” command line option to add new URLs from TXT or CSV file:

    WCExtractor.exe projectfile -at”filename” -s

projectfile: the file name of the project (*.wcepr) to open.
filename – the file name of the CSV or TXT file that contains URLs separated by newlines.
-s – starts the extraction process

You can find some options and examples here.
Mozenda

Since Mozenda is cloud-based, the external data needs to be loaded up into the user’s Mozenda account. That data can then be easily used as part of the data extracting process. You can construct URLs, search for strings that match your inputs, or carry through several data fields from an input collection and add data to it as part of your output. The easiest way to get input data from an external source is to use the API to populate data into a Mozenda collection (in the user’s account). You can also input data in the Mozenda web console by importing a .csv file or importing one through our agent building tool.

Once the data is loaded into the cloud, you simply initiate building a Mozenda web agent and refer to that Data list. By using the Load page action and the variable from the inputs, you can construct a URL like http://www.amazon.com/gp/product/%asin%.
Helium Scraper

Here is a video showing how to do this with Helium Scraper:


The video shows how to use the input data as URLs and as search terms. There are many other ways you could use this data, way too many to fit in a video. Also, if you know SQL, you could run a query to get the data directly from an external MS Access database like
SELECT * FROM [MyTable] IN "C:\MyDatabase.mdb"

Note that the database needs to be a “.mdb” file.
WebSundew Data Extractor
Basically this allows using input data from external data sources. This may be CSV, Excel file or a Database (MySQL, MSSQL, etc). Here you can see how to do this in the case of an external file, but you can do it with a database in a similar way (you just need to write an SQL script that returns the necessary data).
In addition to passing URLs from the external sources you can pass other input parameters as well (input fields, for example).
Screen Scraper

Screen Scraper is really designed to be interoperable with all sorts of databases. We have composed a separate article where you can find a tutorial and a sample project about scraping Amazon products based on a list of their ASINs.

Microsys A1 Website Scraper Review

The A1 scraper by Microsys is a program that is mainly used to scrape websites to extract data in large quantities for later use in webservices. The scraper works to extract text, URLs etc., using multiple Regexes and saving the output into a CSV file. This tool is can be compared with other web harvesting and web scraping services.
How it works
This scraper program works as follows:
Scan mode

    Go to the ScanWebsite tab and enter the site’s URL into the Path subtab.
    Press the ‘Start scan‘ button to cause the crawler to find text, links and other data on this website and cache them.


Important: URLs that you scrape data from have to pass filters defined in both analysis filters and output filters. The defining of those filters can be set at the Analysis filters and Output filters subtabs respectively. They must be set at the website analysis stage (mode).
Extract mode

    Go to the Scraper Options tab
    Enter the Regex(es) into the Regex input area.
    Define the name and path of the output CSV file.
    The scraper automatically finds and extracts the data according to Regex patterns.

The result will be stored in one CSV file for all the given URLs.

There is a need to mention that the set of regular expressions will be run against all the pages scraped.
Some more scraper features

Using the scraper as a website crawler also affords:

    URL filtering.
    Adjustment of the speed of crawling according to service needs rather than server load.

If  you need to extract data from a complex website, just disable Easy mode: out press the  button. A1 Scraper’s full tutorial is available here.
Conclusion

The A1 Scraper is good for mass gathering of URLs, text, etc., with multiple conditions set. However this scraping tool is designed for using only Regex expressions, which can increase the parsing process time greatly.

Google Webmaster Tools to have more insight into site content and web traffic

The content war is currently waging on the web. What particular keywords bring organic traffic to my site? Where is my website positioned in the users’ organic search using these keywords? How does my page get top ranked? These concerns are relevant to many site owners and business bloggers. This topic is to help you to master Google Webmaster Tools as the means to see how your page content performs before the click.


Along with Google Analytics why not use complementary Google Webmaster Tools for better insight into how your website is viewed and hit through organic search results? My partner regards paid campaigns of no worth in comparison to actual organic site traffic. (In a similar manner both of us highly esteem organic food as opposed to modern “fast-food-chemicals”.) So he and I always check the organic traffic through Google Analytics. But what happens before search visitors jump into the website? Of course we want to position our site for certain search keywords for the best nitch web indexing. Webmaster Tools is the first means for us to check the keywords upon which a site gets its organic traffic. The figure below shows the basic interactions in Google Analytics and Webmaster Tools for overseeing: If you don’t need the setting up guide for Webmaster Tools then jump directly to How Google sees your content – Content Keywords
How to set up Google Webmaster Tools

These are the easy steps:

    Sign up for Webmaster Tools. While signing up use a Google Account that has administrative access to your Google Analytics account. That will make it easy to connect them.
    Enter URL of your website and Webmaster Tools will issue a verification code that is an HTML file to be stored in the root directory.
    Then upload this HTML file by FTP into the root directory of your site on the hosting server; that should be very elementary. If you have no FTP access to the site, turn to a developer for assistance.
    Press “Verify” and Webmaster Tools will confirm your ownership.

After 24 hours Webmaster Tools will start to show the web traffic info for the set account.

Connect Google Analytics with Webmaster Tools

Log onto the site in your Google Analytics. On the dashboard go to Traffic Sources -> Search Engine Optimization -> Queries. There you will be asked to enable Webmaster Tools. Choose “Set up Webmaster Tools data sharing” and you will see your new Webmaster Tools account to connect. Press “Apply” and now all your web statistic info from the Webmaster Tools gauge (impressions, clicks, average position and CTR) is available at Traffic Sources -> Search Engine Optimization -> Queries in Google Analytics. Now you are fully armed to track how your content is served by Google “before the visitor click”.
How Google sees your content – Content Keywords

Webmaster Tools displays how the content of your site is perceived by Google. So, if you want to see how Google has indexed your website, go to Webmaster Tools, on the Dashboard go to Optimization->Content Keywords. Now you can see the keywords that lead most frequently to your website. It’s also based on these keywords that Google shows your website in the  search results. Much brain food for your publishing and SEO strategy! Looking at the first 11 keywords it was clear that scraping, scraper and extraction position a blog in the data extraction / data scraping nitch (see the figure below). The word data alone is most significant, though it is unlikely to rank the blog at the top if searched:
What people preview in search when running search queries

Besides the static site content indexed by Google thru keywords (and sure meta tags), Webmaster Tools allows you to see the search queries results summary relevant to your website. Go to  Traffic->Search Queries to see the top search queries for which your site appeared in search results. This is the best means to watch the site’s performance in terms of impressions, clicks, click through rate (CTR) and average position in any given time span: So based on the picture above, a website got 1600 clicks in the time span. This figure largely matches on-site visitor flow analytics. The blue line indicates the total page impressions. It reveals the general demand of the web audience for the set of keywords upon which your website or blog is positioned. If the average position for a given page or post is more then 10, the page is most likely not showing up in the first page of search results. These data are quite trustworthy. Backlinks as well as top referrers to your website can be seen if you choose Traffic -> Links to Your Site. Webmaster Tools provides even more website relevant features; here I’ve chosen the most relevant ones that impact web traffic improvement. I hope using Webmaster Tools will be of much benefit in making any web page adjustments you need.

Benefits of Online Data Entry

There is no doubt that data entry is a vital part of business development because no organized activity can take place without the organized manipulation of data. But, even though the correct manipulation of data is at the heart of any enterprise, it is also true that this is an activity that is time consuming and repetitive. In the past, businesses had to dedicate a good portion of their work hours for the mind-numbing job of feeding data. However, with the arrival of the internet, there have been revolutionary changes in the way business handle data.

These days, a good volume of data entry work is being carried out online. Many companies, regardless of their size, are outsourcing this kind of work. This is more so in developed countries like the US, UK and Europe. These countries outsource such work to a pool of educated youth working from developing nations like China, India and Malaysia. The Internet is what makes this possible. Since the job is being done in a different country where currency rates are relatively low, the parent company is able to cut costs. More importantly, many companies have begun to realize that the time and effort they are putting into data entry could be routed to processes that will help the business grow. Outsourcing frees the resources in the parent company, which in turn allows the parent company to dedicate more time and energy to improving their core competency.

Reputed outsourcing partners hire well educated people who have the technical expertise, the knowledge and the language skills to handle data entry jobs efficiently and reliably. By allowing these experts to streamline the data entry process, businesses get two benefits at once. On the one hand, they cut costs and improve their bottom lines. On the other hand, they hire a dedicated team of professionals who specialize in data entry jobs. Thus, there is no compromise in quality. In fact, they can expect good results from reputed outsourcing partners because of the excellent remuneration they receive. The differences in foreign currencies make outsourcing a lucrative source of income for many companies.

However, it is important to remember that online data entry is fraught with risks. The first and probably the only element of risk is the quality of the service provider. Choose an outsourcing partner who has sufficient experience in the field and has a solid reputation servicing international clients. In case the outsourcing company has a branch in the same geographical location, it becomes easier to liaise with them. Experienced outsourcing companies already have enough exposure to the needs of growing companies and can be trusted to deliver excellent quality and within prescribed time limits.

In short, if you choose wisely, you can be assured of quality work and complete satisfaction.

Outsourcing Data Entry- The Outsourcing Success Story

Although a company’s data entry work is often among the most monotonous jobs imaginable, they require the skills of trained personnel. For all its tedium, data entry is essential to a company’s survival, without being one of its core operations, and many companies have turned to outsourcing data entry work so that its employees can spend their time on more lucrative matters. The data entry tasks will be performed by competent contractors in developing nations like India, Malaysia, China, and Brazil, and for a much lower cost than it would require if it continued to be done in-house.

How Outsourcing Data Entry Works

Companies have been outsourcing data entry work almost as long as the global technological development has supported outsourcing. The outsourcing of data entry work requires a company to either mail hard copies of its data forms, or scan and email or fax, electronic images of them, to the outsource contractors who will complete the data entry job.

The data entry workers then input information into a database on a computer, and either store it on a magnetic medium for shipping or email it back to the sending company in encrypted form.

Because data entry jobs do not require and advanced degree of computer savvy, outsourcing data entry work is far less difficult than outsourcing more complex processes. Data entry work does not demand an ongoing communication between the outsourcing company and the data entry provider, and the outsourcing of data entry work to date entry firms in underdeveloped nations has for the most part been one of the big outsourcing success stories.

Freelance Data Entry Outsourcing

The Internet, of course, has played a huge part in the increase of data entry workers, in particular in poorer countries, who freelance their services. A simple Internet search will bring up dozens of sites shopping the services of data entry coders who work for what would be considered starvation wages in Europe or the US.

These data entry workers normally price their services according to both the sizes of the requested projects, and their own work histories. Outsourcing data entry [http://www.1outsourcing.com/Articles/Outsourcing_Call_Center.php] work to these coders is usually a matter of posting the specifics of a job, and letting the various coders make bids on it. The going rate for data entry jobs can begin at less than $100, but there is no guarantee that the coder whose bid is accepted will actually complete the job as specified. While most of the reverse auction sites will return the money for an incomplete or substandard effort, the data entry still has not been finished, and business operations may fall behind until it is.
