Scraping Data Behind a CAPTCHA

How much does the highest paid person in the Brazilian Federal Senate earns? That's the question I asked myself a few weeks ago, and one that should be easy to answer. In Brazil, every public body must publish its employees' salaries online, but some do so in a terrible way. The Federal Senate is one of these.

To access its data you have to not only fill in your personal info, but also solve a CAPTCHA for each salary you want to see. With no other tricks, it would take ages to answer my question. I needed a way to gather all salaries and compare them. But how to scrape a page that's "protected" behind a CAPTCHA?

Decaptcher is a company that sells CAPTCHA-solving services. They provide an API that you can send an image, and get the contained text. It's really cheap (US$ 1.38 per 1.000 CAPTCHAs), and works well, albeit a bit slow (30~40 secs). They promise a success rate of over 95%, but I got only 43% in my tests. Probably because the CAPTCHAs I'm sending are really hard to read.

Their API is simple to implement, with only 3 actions (upload, refund, and balance). There're examples in C# and PHP, and I've hacked together one in Ruby. For a bit more than US$ 5.92, I was able to access and publish the salaries of 4,487 public servants in http://senado.cc.

There're many other companies that offer the same service, like Death by CAPTCHA, Bypass CAPTCHA, Beat CAPTCHA, and Antigate. These services allow us to access public data that would be unreachable otherwise, but they might be considered illegal in some countries. As we're not breaking the CAPTCHA, but paying people to solve them, we should be fine. But don't take my word for it: ask a lawyer.

Collecting Data With Web Scrapers

There is a large amount of data available only through websites. However, as many people have found out, trying to copy data into a usable database or spreadsheet directly out of a website can be a tiring process. Data entry from internet sources can quickly become cost prohibitive as the required hours add up. Clearly, an automated method for collating information from HTML-based sites can offer huge management cost savings.

Web scrapers are programs that are able to aggregate information from the internet. They are capable of navigating the web, assessing the contents of a site, and then pulling data points and placing them into a structured, working database or spreadsheet. Many companies and services will use programs to web scrape, such as comparing prices, performing online research, or tracking changes to online content.

Let's take a look at how web scrapers can aid data collection and management for a variety of purposes.

Improving On Manual Entry Methods

Using a computer's copy and paste function or simply typing text from a site is extremely inefficient and costly. Web scrapers are able to navigate through a series of websites, make decisions on what is important data, and then copy the info into a structured database, spreadsheet, or other program. Software packages include the ability to record macros by having a user perform a routine once and then have the computer remember and automate those actions. Every user can effectively act as their own programmer to expand the capabilities to process websites. These applications can also interface with databases in order to automatically manage information as it is pulled from a website.

Aggregating Information

There are a number of instances where material stored in websites can be manipulated and stored. For example, a clothing company that is looking to bring their line of apparel to retailers can go online for the contact information of retailers in their area and then present that information to sales personnel to generate leads. Many businesses can perform market research on prices and product availability by analyzing online catalogues.

Data Management

Managing figures and numbers is best done through spreadsheets and databases; however, information on a website formatted with HTML is not readily accessible for such purposes. While websites are excellent for displaying facts and figures, they fall short when they need to be analyzed, sorted, or otherwise manipulated. Ultimately, web scrapers are able to take the output that is intended for display to a person and change it to numbers that can be used by a computer. Furthermore, by automating this process with software applications and macros, entry costs are severely reduced.

This type of data management is also effective at merging different information sources. If a company were to purchase research or statistical information, it could be scraped in order to format the information into a database. This is also highly effective at taking a legacy system's contents and incorporating them into today's systems.

Overall, a web scraper is a cost effective user tool for data manipulation and management.

How to Scrape Websites for Data without Programming Skills

Searching for data to back up your story? Just Google it, verify the accuracy of the source, and you’re done, right? Not quite. Accessing information to support our reporting is easier than ever, but very little information comes in a structured form that lends itself to easy analysis.

You may be fortunate enough to receive a spreadsheet from your local public health agency. But more often, you’re faced with lists or tables that aren’t so easily manipulated. It’s common for data to be presented in HTML tables — for instance, that’s how California’s Franchise Tax Board reports the top 250 taxpayers with state income tax delinquencies.

It’s not enough to copy those numbers into a story; what differentiates reporters from consumers is our ability to analyze data and spot trends. To make data easier to access, reorganize and sort, those figures must be pulled into a spreadsheet or database. The mechanism to do this is called Web scraping, and it’s been a part of computer science and information systems work for years.

It often takes a lot of time and effort to produce programs that extract the information, so this is a specialty. But what if there were a tool that didn’t require programming?

Enter OutWit Hub, a downloadable Firefox extension that allows you to point and click your way through different options to extract information from Web pages.

How to use OutWit Hub

When you fire it up, there will be a few simple options along the left sidebar. For instance, you can extract all the links on a given Web page (or set of pages), or all the images.

If you want to get more complex, head to the Automators>Scrapers section. You’ll see the source for the Web page. The tagged attributes in the source provide markers for certain types of elements that you may want to pull out.

Look through this code for the pattern common to the information you want to get out of the website. A certain piece of text or type of characters will usually be apparent. Once you find the pattern, put the appropriate info in the “Marker before” and “Marker after” columns. Then hit “Execute” and go to town.

An example: If you want to take out all the items in a bulleted list, use <li> as your before marker and </li> as your after marker. Or follow the same format with <td> and </td> to get items out of an HTML table. You can use multiple scrapers in OutWit Hub to pull out multiple columns of content.

There’s some solid help documentation to extend your ability to use OutWit Hub, with a variety of different tutorials.

If you want to extract more complicated information, you can. For instance, you can also pull out information from a series of similarly-formatted pages. The best way to do this is with the Format column in the scraper section to add a “regular expression,” a programmatic way to designate patterns. OutWit Hub has a tutorial on this, too.

OutWit Hub isn’t the only non-programming scraping option. If you want to get information out of Wikipedia and into a Google spreadsheet, for instance, you can.

But even when pushed to the max, OutWit Hub has its limitations. The simple truth is that using a programming language allows for more flexibility than any application that relies on pointing and clicking.

When you hit OutWit’s scraping limitations, and you’re interested in taking that next step, I recommend Dan Nguyen’s four-post tutorial on Web scraping, which also serves as an introduction to Ruby. Or use programmer Will Larson’s tutorial, which teaches you both about the ethics of scraping (Do you have the right to take that data? Are you putting undue stress on your source’s website?) while introducing the use of the Beautiful Soup library in Python.

Converting Facebook SMB Pages to Websites

Various companies have built SMB websites and landing pages by scraping the Web. PaperG comes to mind. How about using Facebook. BIA/Kelsey data from our Local Commerce Monitor shows that more than 40 percent of U.S. SMBs have Facebook pages. Many, however, still don’t have standalone websites.

Exai, a spin off of TrafficMedia, is pursuing this path with a freemium model. Companies can opt to have a free, custom-created, mobile-optimized site based on their Facebook page, but can also upgrade to an enhanced version for $3-6 a month. The enhanced version includes maps, Google indexing and other features.

TrafficMedia was originally based on the idea of custom created sites that don’t use a template. Exai’s concept theoretically makes website building even easier by populating the content for the SMB.

The businesses are recruited via targeted Facebook ads. Most of the SMBs are outside of the U.S. and Western Europe , where Facebook’s advertising rates are less affordable for startups. They largely come from the Middle East, North Africa, The Far East and Asia. The company is also building via word of mouth, including a contest it is hosting for best website built from Facebook content.

Founder Gal Moran, a serial entrepreneur, says the company is currently focused on Facebook, but will soon also scrape other social media sites, such as LinkedIn. Facebook’s appeal is that it is universally used by a high percentage of SMBs. The company currently has built 10,000 SMB sites from Facebook, and is adding 1,000 + new sites a day.

Moran adds that Facebook has been very helpful , even sending staffers from Ireland to help facilitate things (living up to a promise made by Facebook exec Dan Levy at ILM West to help third party sites work with it). Exai has also gotten support from Google, which is able to leverage Exai for its ability to index Facebook-only content that previously was only available to Microsoft Bing.

Do Facebook SMB pages generally have enough content to make a compelling SMB website? It is a good question. It probably varies. At the very least, they provide a head start for the majority of SMBs that aren’t self-starters.

Website Data Scraping Are Relatively Easy To Use

Have you ever heard "data scraping?" Scraping data scraping technology to new technology and a successful entrepreneur made his fortune by taking advantage of the data is not.

Sometimes the owner of the website automatically harvest your data will not be much fun. Webmaster tools or techniques contained in the website retrieving block certain IP addresses from using their websites to disallow web scrapers learned to use. The all eventually left may be blocked.

Venus is a modern solution to the problem. Proxy data scraping technology solves this problem by using proxy IP addresses. Each time you scraping the data the program execute an exit from a website, website think it is coming from a different IP address. The owner of the website, the proxy data scraping a short period of increased traffic from all over the world look like.

Now you might ask yourself, "do I get for my project in which the data scraping technology Proxy?" "Do it yoursel f" solution, but unfortunately, not all madly. Hindi to mention. The proxy server you choose to rent consider hosting provider, but somewhat pricey option, but certainly better than the alternative would be incredibly dangerous (but) free public proxy server.

There are literally thousands of free proxy servers located all over the world that are relatively simple to use. But finding it misleading. Many sites list hundreds of servers, but that's hard to find, open, and support the type of protocol you need patience, trial and error, can be a lesson. But if you're working behind the scenes to the public in finding a pool is not successful, there is still the inherent risk of using it. First, you do not know which server belongs to or what the task of going to a server in one place. Through a public proxy requests or to transmit sensitive data is a bad idea.

Proxy data scraping for a less risky situation is to rent a rotating proxy connection to cycle thro ugh a large number of private IP addresses. Company as large anonymous proxy solutions, but often carry a pretty hefty setup fee to get going.

After performing a simple Google search, I quickly that the purposes scraping anonymous company that provide access to data in the proxy server.

Some challenges will be to:

That’s Not A Valid Coupon Code, But This Is

Every now and again we get a call from a customer asking why their coupon code isn’t working.  In pretty much every case, we have to give them the bad news that the coupon code they have isn’t a valid code after which, the customer asks why they’ve finding that code listed on coupon sites.

So here’s the skinny on coupon codes and coupon code websites.  There are literally thousands of websites that list coupon code and in most cases, they are reliant on their visitors to tell them if the code is valid or not.  Some of the codes are valid, but most are either expired or never existed in the first place.  Most of these websites aren’t trying to overtly trick you.  What often happens is that they see the code on another coupon site, scrape it and add it to their own site without bothering to check the validity.

Because there’s no way for us to police this (as there are too many sites and there’s no good way for us to get site owners to take down bogus or expired codes), I figured I’d list out a few key points to help you all sift through the coupon mess:

    PoolDawg almost never offers “% off” discount codes.  There are some exceptions to this rule (as we typically do something special for Black Friday and sometimes let our player reps promote a % off code), but generally speaking, if you find a code that says %10 off your order, you can safely assume that its bogus.  Some of the known bogus codes floating around are PDAWG, PDAWG10, PD10 and 10OFF.  None of these work, nor will they ever work.
    If you see a code that says something along the lines of “xx% off orders of $yy or more”, just skip it.  I personally do all the coupon codes and have not ever ran this style of offer.  If I worked for Eddie Bauer or J. Crew it would be a different story, but we don’t get the margins that the folks in the clothing business do.
    For the most part, any coupon codes we do have will be distributed via our email list.  Sometimes we also put them in our automated emails as well, so your best chance of getting a coupon code is by signing up to our email list (you can find the sign upin the lower right hand corner of our website).
    You don’t need a coupon code to take advantage of our standard special offers (free shipping @ $99+, free gifts with most pool cues, 20% off MSRP for most pool cues, etc)
    If you have a question, you can always call us.  Just don’t be mad at us if the coupon code you have isn’t a real code.  Be mad at whoever gave you that code. :-)

In all seriousness, the vast majority of the coupons we do are along the lines of “spend $xx and get a free tchotchke with the PoolDawg logo on it”.  For example, if you enter the code “comeonback” and your order is $25 or more, we’ll send you a free PoolDawg coin holder (seriously, we will.  This is a real coupon code that doesn’t expire until the end of 2011).

Ok, that’s all for now.  Hopefully this demystifies the coupon codes a bit.
