We discuss and evaluate metasearch engines.

Class held on 12/01/2008. Student notes are available on this page. Possible questions are available on this page.

Class structure

  1. Go through “At beginning of class” information
  2. Go through highlights of some of the amazing search tools that are available.
  3. Work on exercises

At beginning of class

  1. Blogs — I have graded a bunch.
    • ummmm: “definately”? “it's” vs. “its”
  2. Rest of the semester:
    1. 12/03: Yahoo
      • same protocol for the visit
    2. 12/08: Semester summary, project unveiling
  3. You still need to post blog entries that received a “10”
  4. Go over any other announcements you might have missed since last class.
  5. Check the start page for any blogs you might be interested in that you might have missed.

My notes

The search community has a tool called a meta-search engine. These tools derive their functionality from other search engines. A complicating factor is that there are two very different types of tools that are called meta-search engines. The search community does not recognize these subtypes, but they are very real and quite significant:

Integrated search for multiple search engines
the meta-search engine uses an algorithm to combine the results from multiple search engines into one result list
Unified interface for separate search engines
the meta-search engine provides a single interface, enabling easy and quick switching between the results of different search engines

These are very different tools. In the first case, the functionality provided by the meta-search engine revolves around an informed method of combining the results of multiple search engines, while in the second case the functionality is simply based on providing a unified interface while simply passing through the results from one external search engine at a time.
