Parts of a search engine
  • Spiders
  • Follow links on web to request pages that have
    either not been indexed or have been updated
    since last index
  • Index (catalog)
  • Large, slightly outdated collection of content
    which roughly represents the content of the web

Parts of a search engine
  • Meta Tags
  • Allow specification of keywords/concepts
  • Helpful when words have more than one meaning
  • Spiders will search page and change meta tags if
    words do not match up. Prevents false
    categorizing with popular keywords.

Receivers
  • Who uses search engines?
  • From a March 2004 survey of 1,649 people
  • 56 use search engines on a daily basis
  • Only 13 use different search engines for
    different types of searches
  • 57 use the same search engine. Of those people,
    the top 3 are Google, Yahoo and MSN.

    professionals (38) and students (27).

Receivers
  • Who uses search engines?
  • From this info we can conclude
  • People of all ages use search engines and half
    use them on a daily basis

Benefits
  • Easy to use
  • Search vast databases
  • Sophisticated searching often available

Description SMCR BCV
Competition Future Summary
14
Costs
  • The web is growing quicker than it can be
    indexed.
  • Search engines slow down because of indexing new
    web pages
  • Queries currently limited to keywords, resulting
    in matching random words scattered across large
    pages (as opposed to limiting matches within a
    paragraph or phrase)

Description SMCR BCV
Competition Future Summary
15
Costs
  • Many dynamically generated sites are not
    indexable, resulting in the invisible web
  • Some search engines do not rank by relevance, but
    rather by how much the websites pay
  • Hundreds of generated sites use tricks to
    manipulate a search engine into displaying them
    higher in results

Description SMCR BCV
Competition Future Summary
16
Costs
  • How important are the costs to users and how can
    usage be increased?
  • Somewhat important
  • Sites indexed more by relevancy
  • Use a proximity-search option, which uses a
    search bracket to limit matches within a
    paragraph or phrase
  • Eliminating linkspam in searches
