Title
¬The design of World Wide Web search engines : a critical review
Source
Program. 31(1997) no.2, S.131-145
Year
1997
Abstract
Presents a state of the art review of WWW search engines from the earliest Internet precursors and noting: prblems inherent in the current range of WWW search engines; problems of searching the WWW (link persistence and lack of integrated search software); and analyzing the resulting search engine types (keyword or directory). Compares search engines of all types across their generic features (database content, retrieval software, and search interface), rather than on a search engine by search engine basis. Considers wider information access issues arising from the nature of the Internet and Web search engines and proposes a general strategy for using web search engines. Comments on the irony that a unitary global information space accessible via 1 freely accessible software package (WWW client browser) should be so balkanized by a plethora of search engines in complete reverse of the traditional world of printed, CD-ROM and online databases, where a limited number and comparatively stable range of search tools attemps to homogenize a large number of physically separate and disparate collections
