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…

Introduces a special issue on research on hypertext systems and information retrieval. Systems design aspects, including navigation models, link weighting, multiple representation techniques, automatic authoring, user modelling, varying levels of abstraction, and evaluation techniques are addressed. (EA)

Describes the development of a system to retrieve images for an international project that is producing a pictorial dictionary of classical mythology, the Lexicon Iconographicum Mythologiae Classicae. Applications to other types of information are discussed, two classification systems for Art History are described, and design principles for…

Outlines the file structure requirements for a microcomputer-based information retrieval system using FoxPro, a relational database management system (DBMS). Issues relating to the design and implementation of such systems are discussed, and two possible designs are examined in terms of space economy and practicality of implementation. (15…

Argues that access to hypertext documents in read-only forms contradicts the assumption that hypertext removes the distinction between author and reader, and discusses the implications for authors of hypertext documents. The creation of hypertext versions of journal articles and a database of such articles are described. (four references) (CLB)

Discusses access to nontextual documents in large multimedia document bases. A hybrid information retrieval model, using queries in a hypertext environment for location of browsing areas, is presented; and two experiments using cluster-based descriptions of content are reported. (23 references) (EA)

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…

Presents a theoretical framework for navigation in information retrieval systems and describes a prototype retrieval system that was developed to investigate navigation. The use of a visual interface in a spatial representation scheme is described, and results of a user-based evaluation of the system are reported. User questionnaires are appended.…

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)

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)…

Discussion of the need for distributed information retrieval systems focuses on a model system, Fulcrum FUL/Text. Differences from distributed database management systems are described; system design is discussed; implementation requirements are explained including remote operation calls (ROC's); and a prototype simulation model based on FUL/Text…

Suggests that known sources of name variation and error in information systems must be addressed through improved retrieval techniques. Argues that a culture of data stewardship in which fewer errors are introduced in the handling of personal names can be achieved through greater awareness of problems specific to handling of names, and the design…

Presents evidence to show that the body plays a continuing and fundamental part in the process of thinking and the development of the knowledge used to think. Topics discussed include knowledge structures and representations; artificial intelligence; feeling; learning processes; models of knowledge; information retrieval; and implications for…
