Examines future implications and significant trends in the field of scientific technical information, including (1) decentralized preparation and collection of formalized input bibliographic and/or factual data, (2) centralized world-wide processing of both kinds of data bases, and (3) nationally decentralized output information services, and…

Defines and discusses bibliometrics, particularly as carried out in automated systems. The specific requirements to which data should conform to support bibliometric analysis are detailed and explained, and the Intelligent Gateway of the Lawrence Livermore National Laboratory is described. (15 references) (Author/CLB)

A procedure for adjusting queries to retrieve more documents for a user by automatically selecting and broadening the descriptors from relevant documents is described. Although more computing is required, recall and precision are superior to traditional searching. (KP)

Examines early and current approaches to automatic thesaurus construction and describes an approach to automatic generation of global thesauri based on the term discrimination value model and on an appropriate clustering algorithm. Preliminary results of implementation of the method are reported. (46 references) (Author/MES)

Describes the design of a prototype rule-based system for the automation of descriptive cataloging from title pages. The discussion covers the results of tests of the prototype, major impediments to automatic cataloging from title pages, and prospects for further progress. The rules implemented in the prototype are appended. (16 references)…

Describes an information retrieval system component that taps into the expertise of users by automatically drawing conclusions from actual search behavior about possible thesaurus entries. The processes of knowledge acquisition, explicit or implicit confirmation by users, knowledge verification, and generation of final results are discussed.…

Presents model of algorithm design (activity in software development) based on analysis of protocols of two subjects designing three convex hull algorithms. Automation methods, methods for studying algorithm design, role of discovery in problem solving, and comparison of different designs of case study according to model are highlighted.…

Describes SCISOR (System for Conceptual Information Summarization, Organization and Retrieval), a prototype intelligent information retrieval system that extracts useful information from large bodies of text. It overcomes limitations of linguistic coverage by applying a text processing strategy that is tolerant of unknown words and gaps in…

Describes a simplified process that can be used by computer departments in businesses to measure fulfillment of user requirements, with emphasis on practical interpretation and usefulness of results. The methodology is based on a set of minimum criteria determined by the organizational environment. An example using a spreadsheet implementation is…

Describes work performed under the Spelling Error Detection Correction Project (SPEEDCOP) at Chemical Abstracts Service to devise effective automatic methods of detecting and correcting misspellings in scholarly and scientific text. The trigram analysis technique developed determined sites but not types of errors. Thirteen references are listed.…

Describes method of automatic document classification in which documents classed as QA by Library of Congress classification system were clustered at six thresholds by keyword using single link technique. Automatically generated clusters were compared to Library of Congress subclasses, and partial classified hierarchy was formed. Twelve references…
