CS297 Proposal

Smart Search: A Firefox Add-On to Compute a Web Traffic Ranking

Vijaya Pamidi (

Advisor: Dr. Chris Pollett


Search engines results are given to the user based on the ranking and indexing strategies followed by the search algorithm of a search engine. Currently, there are some tools available like,, which give analytic data for ranking web sites based on web traffic, the number of users who visit a site. Alexa provides the traffic rank for a website based on two factors: The number of users that view a website and the number of pages viewed. The main goal of our project is to create a Smart Search Firefox add-on for the Yioop search engine, an open source search engine developed by my project advisor, Dr. Chris Pollett. This add-on will provide similar analytic data to the Yioop search engine. Smart search considers three main factors to get a rank for a website, these factors are:

  • Number of users that view a website.
  • Probability that user leaves some other website and enters the current one and the probability that user clicks on the link provided on the current page.
  • Getting the user review for a result: if the user finds a particular result useful clicks on the + sign. A + will increment the rank of a page or website

Smart search takes these three basic factors into consideration and sends back data to the Yioop search engine periodically. With the results received from the Smart Search tool, the Yioop search engine refines the search results. Eventually, users would benefit from these better search results.

The full project will be done when CS298 is completed. The following will be done by the end of CS297:

1. Study and understand set of Algorithms [Page Rank Algorithm, Hits, Bloom Filters, Porter stemming Algorithms]

2. Study and Report on Dr.Pollett's search engine code

3. Writing simple extension to Firefox

4. Adding a branch to the search Trunk of search engine code and make it communicate with tool

5. CS 297 Report
