Proposes a classification of elliptical utterances based on a pragmatic analysis of the intention in information seeking dialogs within natural language understanding (NLU) systems. The traditional classification of ellipsis is described, analysis of the dialogs is discussed, and implications for the design of NLU systems are suggested. (Contains…

Clarifies the idea of information by dividing the range of definitions into different parts and identifying several points of misunderstanding. The discussion covers the sciences relating to the concept of information; the nomenclatures of informatics, informatology, information science, and information sciences; and the multidimensional…

Describes the concept of Information Based Education, provides a theoretical basis for investigating the role of information in education, and begins developing a classification scheme for documenting and distinguishing among information bases. Attributes of information associated with information resources, information skills, information…

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…

Describes and organizes the variables affecting display presentation format (i.e., tables and graphs) in information systems into a classification scheme and creates a framework for research in this area. Two-factor studies are discussed; research recommendations are presented; and Cognitive Match Interface Design is explained. (Contains 31…

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)

Shows how to automatically construct a classification of users and a clustering of documents and cross-references among clusters based on users' information needs. Feedback in the construction of this classification and clustering that allows for the classification to be changed to reflect changing needs of users is also described. (22 references)…

Reports on two empirical studies that examined the nature and causes of information management indeterminism in an online research environment. A knowledge-based design for alleviating indeterminism which contains a system-generated thesaurus and an inferencing engine is proposed. (Contains 63 references.) (JLB)

Suggests the designation of overlapping hierarchies in thesauri, first outlined in 1973, as a key element in progress towards a successful man-machine partnership. Article updates, expands, and provides theoretical background of 1973 proposal; postulates use of the UDC; and suggests means of distinguishing overlapping terms from other…

Describes MANIS, an information system for retrieval of interdisciplinary information in management, which maintains traditional classification but allows the user to combine terms of his choice, where choice is restricted to terms belonging to the systems of traditional classification. (CWM)

Summarizes the similarities between classification systems for catalog selection and information retrieval systems, and discusses system characteristics that allow the use of measures such as recall and precision in system evaluation. (27 references) (Author/CLB)

This review of abstracting policies used by database producers focuses on the degree to which these policies incorporate criteria vital for acceptability of abstracts for free-text searching. Each topic in abstracting policy (abstract type, length, content, and language) is examined to consider its effect on retrieval. (MBR)

Suggests structure based on two sets of principles for deriving meaning from data: Shannon's measure of entropy, which provides means of measuring amount of information in message; and Ranganathan's faceted classification scheme, which provides means of determining number of meaningful data. Syntax, meaning, and semantics of data are discussed.…

Describes a fast algorithm for comparing the lists of terms representing documents in automatic classification experiments. Complexity and running time for the algorithm are compared to other procedures, and a short algol-like routine is presented in the appendix. Eight references are included. (Author/BK)

Develops a framework for analyzing the value of information, information products, and services from the viewpoint of information use, and analyzes the practical values of different types of information to study the problems involved in assessing their value-in-use and exchange value. Existing research studies are analyzed using this approach.…
