Abstract:

Thesauri, subject headings, and keyword searching have been the customary strategies used for location of materials. Categorizing by subject or descriptor term creates a thesaurus of specified terms, a controlled vocabulary. Searching this list identifies cataloged items. However, new computing techniques- artificial intelligence, natural language processing, relevancy feedback, query-by-example, and concept-based searching- have added a new sophistication to information retrieval. Robots, computers that search the web using these new techniques (AKABoolean searches spiders or wanderers), offer the 'net searcher a higher degree of precision in retrieval. The presentation is targeted toward WEB searchers, in particular, reference librarians and those who navigate the Internet on a frequent basis. This presentation will look at search engines, comparing search techniques and noting differences. The workshop will identify use of new computing strategies for information retrieval within each engine. 'Spinning a Web Search' requires an electronic classroom with large screen projection for Netscape (or other browser), or classroom demonstration will focus the workshop: handouts (with exercises) will be provided for clarification and training. The workshop will be one hour.
