Effectiveness of Web Data Mining Through Web Research

Web data mining is systematic approach to keyword based and hyperlink based web research for gaining business intelligence. It requires analytical skills to understand hyperlink structure of given website. Hyperlinks possess enormous amount of hidden human annotations that can help automatically understand the authority. If the webmaster provides a hyperlink pointing to another website or web page, this action is perceived as an endorsement to that webpage. Search engines highly focus on such endorsements to define the importance of the page and place them higher in organic search results.

However every hyperlink does not refer to the endorsement since the webmaster may have used it for other purposes, such as navigation or to render paid advertisements. It is important to note that authoritative pages rarely provide informative descriptions. For an instant, Google's homepage may not provide explicit self-description as "Web search engine."

These features of hyperlink systems have forced researchers to evaluate another important webpage category called hubs. A hub is a unique, informative webpage that offers collections of links to authorities. It may have only a few links pointing to other web pages but it links to a collection of prominent sites on a single topic. A hub directly awards authority status on sites that focus on a single topic. Typically, a quality hub points to many quality authorities, and, conversely, a web page that many such hubs link to can be deemed as a superior authority.

Such approach of identifying authoritative pages has resulted in the development of various popularity algorithms such as PageRank. Google uses PageRank algorithm to define authority of each webpage for a relevant search query. By analyzing hyperlink structures and web page content, these search engines can render better-quality search results than term-index engines such as Ask and topic directories such as DMOZ.

Scraping Amazon item offers

In my pet project Dealesque, I am trying to compare all offers on a number of Amazon items, the idea being that it can help decide which offers to use to minimize shipping and total cost. Using Amazon Product Advertising API was the logical first step, but it doesn’t return all the offers for an item. It does however return the “more offers URL” for each item. Hence, the old scrapin’ was due, and none too late!

Plain wget-like action would not suffice, since Amazon is taking care to block unwanted traffic. So, mechanize gem to the rescue! It actually allows you to impersonate a real browser:
1
   
agent = Mechanize.new { |agent| agent.user_agent_alias = 'Mac Safari' }

After that, you can navigate the site, click away, read any forms etc.
For scraping, what I actually ended up using was to get the content of the “more offers URL” page and parse it using Nokogiri. Something like:
1
2
3
   
page = agent.get(more_offers_url)
root = Nokogiri::HTML(page.content.strip)
scrape_content(root)

For the current development stage, this is doing just fine. Unfortunately, for production use it will not suffice. There will probably be some traffic throttling from Amazon and some benchmarking will need to be done to determine the limits. Also, proxying the requests will probably be required too. But, I leave this for some other times.

The result of scraping the offers for picked items:
