- Abstract
- Compares the features and performance of 6 Web search engines: AltaVista, Excite, HotBot, Infoseek, Lycos and Northern Light; 2 metasearch engines: Savvy Search and Inference Find; and the question answering system Ask Jeeves. Results of a standard set of 10 questions posed to each service show little overlap between search engines, so it is important to use more than one Web search engine if a comprehensive search is needed. Discusses technology trends and makes recommendations for Web searching. More and better information has become available on the Web in 1998 and each major search engine is developing a niche market and its own personality
