Judit Bar-Ban · 2004
Summary. This chapter discusses Web search engine performance over time. Unlike classical information retrieval systems, the Web is decentralized and dynamic, that is, new pages are added, others are moved and removed, while existing pages may undergo changes. The dynamic nature of Web pages should influence search engine results over time. a set of measures is introduced to evaluate search engine performance in this constantly changing environment. The chapter also discusses in short search engine architecture, models and characterizations on the growing and changing Web, and reviews a number of small experiences that demonstrate that search engines do not always cope satisfactorily with dynamic changes.
