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…

Applies a prefix trie index, or trie hashing, to the problem of providing fast search times, fast load times, and fast update properties in a bibliographic or full-text retrieval system with inverted files. Statistics are given for a test database consisting of an online catalog at the University of Western Ontario. (Author/LRW)

Describes a system that was developed in Germany for natural language processing (NLP) to improve free text analysis for information retrieval. Techniques from empirical linguistics are discussed, system architecture is explained, and rules for dealing with conjunctions in dependency analysis for free text processing are proposed. (13 references)…

Describes the training and support offered to users upon the implementation of a corporate online text retrieval system, and offers insights from the experience. Areas discussed include training programs and objectives, user support services and support personnel, user documentation, database building, and performance evaluation and measurement.…

Provides a chronology of news library automation and describes the current functions and services of a newspaper library. Areas discussed include clerical tasks, automated clip files, the use of free text searching and field specificity in newspaper databases, the development of online experts, and the impact on the skills required of news…

This paper describes online newsmedia databases which have been intentionally designed to respond to needs for information that is more current than the information in printed indexes or online versions of these indexes. It is suggested that these databases are useful to libraries because, in addition to subject indexing, they have "word…

Outlines the process of a CD-ROM desktop publishing project at Simmons College Graduate School of Library and Information Science. Highlights include the planning process; data generation and database development; data preparation, including data conversion and indexing; full text retrieval; assembly and production; and distribution. (three…

Discusses the role of end users in the design of a multi-format digital library project, ISLA (name derived from Spanish word for "island"), being developed at the University of Southern California library for the study of the Los Angeles region. Topics include spatial and temporal indexing; the geographic information system element;…

Describes the InfoTrac SearchBank based on experiences at the University of Nevada, Reno, libraries where the service is available through the online catalog. Highlights include remote access through the Internet; indexing and abstracting; full-text access to 460 journal titles; a powerful search engine; and business-oriented databases.…

Presents an algorithm that automatically extracts words and phrases containing geographic place names or characteristics from a text document and uses them as input to database functions that use spatial reasoning to approximate statistically the geoposition referenced in the text. Preliminary results and future work are discussed. (28 references)…

Presents guidelines for statistics for Web-based information resources developed by the International Coalition of Library Consortia (ICOLC). Outlines use elements that must be provided: number of queries, menu selections, sessions, turn-aways, and items examined. Discusses privacy; user, institutional, and consortial confidentiality;…

Presents abstracts of 36 special interest group (SIG) sessions. Highlights include the Chemistry Online Retrieval Experiment; organizing and retrieving images; intelligent information retrieval using natural language processing; interdisciplinarity; libraries as publishers; indexing hypermedia; cognitive aspects of classification; computer-aided…

This paper discusses the indexing, collection, and maintenance processes, as well as the retrieval interface, to public digital libraries. The paper begins by briefly surveying both Internet technical report collections and World Wide Web search engines. It goes on to describe a prototype digital library, the New Zealand Digital Library for…

Describes collaboration between the University of California at Berkeley and four other universities to develop interoperable servers containing each participant's Computer Science Technical Reports and to make them available over the Internet using standard protocols. The proposed library architecture, approaches to indexing and retrieval, and…
