Search 2.0 vs Traditional Search

If you want more 2.0 trends here is one described in Read/WriteWeb. Ebrahim Ezzy gives an overview on "search 2.0" vs traditional search:

"Traditional Search (TSE):

Traditional search engines are based on information retrieval technologies. They implement operations such as boolean queries, proximity searches, text relevance and link analysis.

Examples: Google, Yahoo, MSN, Ask

Search 2.0 (S-2.0):

What I'm calling Search 2.0 are actually third generation search technologies. To explain the generations:

  • First-generation search ranked sites based on page content - examples are early yahoo.com and Alta Vista.
  • Second-generation relies on link analysis for ranking - so they take the structure of the Web into account. Examples are Google and Overture.
  • Third-generation search technologies are designed to combine the scalability of existing internet search engines with new and improved relevancy models; they bring into the equation user preferences, collaboration, collective intelligence, a rich user experience, and many other specialized capabilities that make information more productive.

Examples: Swicki, Rollyo, Clusty, Wink, Lexxe"
