Abstract
Search and directory are some of the earliest applications of the World Wide Web. In this chapter, the general architecture of a Web search system is presented. An important aspect of a Web search system is the Web crawler that crawls the World Wide Web by following links and storing this information for processing. The issues in crawling, and how queries are used to retrieve documents is presented. Variants in search such as focussed crawling, meta-search, and dynamic search are also discussed. An overview of Web directory systems and different methods of constructing Web directories are described. Ranking algorithms such as PageRank™ and web ‘social structure’ extraction using Hub/Authority analysis are also covered.
The world is the ever-changing foam that floats on the surface of a sea of silence
