This study examine 60 corporate Web sites to see if they provided support for automatic indexing, particularly use of the robots.txt and Meta tags for keywords and description. Discusses the use of Java and cookies and suggests that an increase in indexing aids would improve overall index coverage of the Web. (Author/LRW)

Discusses index construction for text collections, reviews principal approaches to inverted indexes, analyzes their theoretical cost, and presents experimental results of the use of a single-pass inversion method on Web document collections. Shows that the single-pass approach is faster and does not require the complete vocabulary of the indexed…

In World Wide Web indexing: (1) the creation process is automated; (2) the indexes are merely descriptive, not analytical of document content; (3) results may be sorted differently depending on the search engine; and (4) indexes link directly to the resources. This article compares the indexing methods and querying options of the search engines…

Discussion of information retrieval and automatic indexing in digital libraries focuses on Chinese indexing and cross-lingual information retrieval. Investigates the combination and boundary detection approaches based on mutual information for word segmentation, using lexical and statistical information. Reports results of experiments that…

Describes a fully automated approach for indexing documents that is based on associating textwords in a training set of bibliographic citations with the indexing of journals. Discusses the use of journal descriptors (JDs) in the MEDLINE database that could also be used to search other journal articles, monographs, and Web documents. (Author/LRW)

Character strings were planted in a World Wide Web site (Project Whistlestop) to test indexing and retrieval rates of five Web search tools (Lycos, infoseek, AltaVista, Yahoo, Excite). It was found that search tools indexed few of the planted character strings, none indexed the META descriptor tag, and only Excite indexed into the 3rd-4th site…

Describes a study of the retrieval results of World Wide Web search engines. Research quantified accurate matches versus matches of arguable quality for 200 subjects relevant to undergraduate curricula. Both "evaluative" engines (Magellan, Point Communications) and "nonevaluative" engines (Lycos, InfoSeek, AltaVista) were…

The author argues that traditional library cataloging (MARC) and the online public access catalog (OPAC) are in collision with the world of the Internet because items in electronic formats undergo MARC cataloging only on a very selective basis. Also the library profession initially isolated itself from World Wide Web development by predicting no…
