Discusses the problem of processing fuzzy queries in databases and information retrieval systems and presents a prototype of a fuzzy query processing system for databases that is based on data clustering and uses Pascal programing language. Clustering schemes are explained, and the system architecture that uses natural language is described. (14…

This issue contains nine articles that provide an overview of trends and research in parallel information retrieval. Topics discussed include network design for text searching; the Connection Machine System; PThomas, an adaptive information retrieval system on the Connection Machine; algorithms for document clustering; and system architecture for…

Describes OAKDEC, a program based on decision-making logic that uses expert system techniques to assess the status of a database search and to provide recommendations to the user on how to proceed. The discussion focuses on the use of OAKDEC as a research tool for studying user behavior. (20 references) (Author/CLB)

Discusses and examines two approaches to concept-based retrieval of hypermedia information that improve a user's ability to navigate large systems--term indexing with semantically coupled thesauri and semantic hyperindexing. Visualization of index structures is discussed, and an example, the Cube of Contents retrieval model for the "Active…

Describes the design of a classification scheme for reusable software and the implementation of an information retrieval system for reusable software using the SMART system. Highlights include a review of other systems for reusable software; system design; reorganization of software documentation; and system testing, including recall and…

A hypertext-based thesaurus is proposed as a navigational aid to the subject domain of a bibliographic database. Implementation of a hypertext version of the "Thesaurus of ERIC Descriptors" with database linking strategies is discussed. (44 references) (EA)

Presents an information systems navigation approach using a combination of functionalities encountered in classification processes, Hypertext systems, and information retrieval systems. The first version of the SYRIUS system is described, with emphasis on the user's graphic interface which integrates these functionalities. (26 references) (EA)

Explores the use of visualization to enhance the information retrieval process, particularly in bibliographic retrieval systems. Topics discussed include document retrieval systems; human visualization; the VIBE (VIsualization by Example) system, a prototype system for visualizing a collection of documents; and differences between VIBE and more…

Describes the design of an experimental computer-aided cataloging advisor, Mapper, that was developed to help novice users with the descriptive cataloging of single-sheet maps from U.S. publishers. The human-computer interface is considered, the use of HyperCard is discussed, the knowledge base is explained, and assistance screens are described.…

Describes a collaborative, reuse hypertext system, called MUCH (Many Using and Creating Hypertext). The novel browsing and retrieval characteristics of the system are based on a semantic net connecting documents, thesauri, and discussions. Word patterns are documented for reuse, creating and reorganizing network traversal according to user…

Describes SHRIF, a System for Heuristic Retrieval of Information and Facts, and the medical knowledge base that was used in its development. Highlights include design decisions; the user-machine interface, including the language processor; and the organization of the knowledge base in an artificial intelligence (AI) project like this one. (57…

Provides a conceptual framework for information systems (IS) that can be used in AIDS intervention and prevention (AIP). System components are analyzed, including a database, decision support systems (DSS), expert systems, and software; potential applications of ISAIP are suggested; and an example of a system implemented at Wright State University…

Discusses information retrieval as an inherently interactive process utilizing a variety of information-seeking strategies on informational and meta-informational levels. An interface design for a bibliographic information retrieval system, called BRAQUE (BRowsing And QUEry), that supports user interactions in a two-level hypertext environment is…

Study results indicate that it is feasible to develop automatic name recognition algorithms to distinguish character strings representing names from other character strings occurring in English language titles. This finding offers cautious promise for alleviating some of the labor intensive work of cataloging. (16 references) (Author/SD)

Description of a Canadian research and development project that involved the development of a library information system which would satisfy the needs of a variety of libraries focuses on the technological aspects of the system. Data manipulation is discussed, software is described, standards are considered, and customer requirements are examined.…
