Describes Features, an intelligent Web search engine that is able to perform real-time adaptive feature (i.e., keyword) and document learning. Explains how Features learns from users' document relevance feedback and automatically extracts and suggests indexing keywords relevant to a search query, and learns from users' keyword relevance feedback…

Provides an overview of robots that retrieve World Wide Web documents and index data and then store it in a database. Nine robot-generated databases are described, including record content, services, search features, and sample search results; and sidebars discuss the controversy about Web robots and other resource discovery tools.

Describes a tool that allows people to browse several characteristics of federal statistical data contained in 200 Web sites before committing to any specific site. Presents the design process used and results from usability testing for the Relation Browser tool and makes recommendations for comparable applications. (Contains 11 references.)…

Discussion of office document search procedures focuses on variable bit-block compression (VBC) signature files and extends VBC signatures for document ranking. Topics include weighted VBC and aggregate VBC; word size, in bits, of term frequencies; storage and retrieval; logarithmic scaling and linear scaling; and ranking performance. (LRW)

These six articles discuss knowledge discovery in databases (KDD). Topics include data mining; knowledge management systems; applications of knowledge discovery; text and Web mining; text mining and information retrieval; user search patterns through Web log analysis; concept analysis; data collection; and data structure inconsistency.

Miriam Blake, Library Without Walls Project Leader at Los Alamos National laboratory (LANL), is making this vision a reality. Blake is part of a growing cadre of experts: a techie who is becoming a…

Previous work indicates that semantic categorization decisions for nonexemplars (e.g., deciding that TURBAN is not an animal name) are faster for high-frequency words than low-frequency words. However, there is evidence that this result might depend on category size. When narrow categories are used (e.g., Months, Numbers), there is no frequency…
