Discusses deductive databases and database management systems (DBMS) and introduces a framework for advanced query formulation for end users. Recursive processing is described, a sample extensional database is presented, query types are explained, and criteria for advanced query formulation from the end user's viewpoint are examined. (31…

Proposes a solution to the problem of loading repetitive bibliographic information in a microcomputer-based relational database management system. The alternative design described is based on a representational redundancy design and normalization theory. (12 references) (Author/CLB)

Investigates the role of information retrieval in the enhancement from database management to knowledge base management and considers the relationship between information retrieval and artificial intelligence. Highlights include unstructured databases; storage of internal forms of documents; an example with relational database operations; and…

Shows how deductive data management techniques can be applied to the utilization of data value classifications in information retrieval. A representation of classifications which supports transitive computation is defined, and an operation-oriented deductive query language tailored for classification-based deductive information retrieval in fact…

Describes fast, dynamic update algorithms for document retrieval systems. B-trees are discussed; the M-B-T file directory structure is explained; insertions and deletions in inverted files are described; and performance evaluation is discussed. An appendix provides the formal definition of an M-B-T directory. (Contains 18 references.) (LRW)

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…

Discusses the critical need for tools to manage, access, and disseminate text and image information ranging from free-form ASCII data to scanned documents stored on optical media. Current types of integrated text/image databases are described and the advancement of technology toward systems that manage large collections of documents made up of…

Discusses the development of multiobject databases called large data constructs (LDC), which may contain images and recorded or synthesized voice as well as text. Virtual reality and cyberspace are discussed, selectivity and database content are examined, database management systems are described, and retrieval options are reviewed. (three…

Describes a conceptual model for integrating short scientific texts, which extends classical text storage and retrieval. A brief comparison with related approaches such as case-based reasoning and classification-based reasoning is also provided. (13 references) (Author/KRN)

This document contains abstracts of papers on database design and management which were presented at the 1986 mid-year meeting of the American Society for Information Science (ASIS). Topics considered include: knowledge representation in a bilingual art history database; proprietary database design; relational database design; in-house databases;…

Describes a study that examined the ability of the dBase database management system to perform secondary key retrieval on multivalued data items. The results are presented as time cost relative to the number of matching records, and situations in which a different management system might be appropriate are identified. (CLB)

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…

Examines recent trends in research in natural language processing and discusses some applications of this research to the solution of information management problems. The article emphasizes that the importance of natural language processing systems is reflected in their frequent use in support of other computer programs. (71 references) (CK)

Examines why the "paperless office" has failed to materialize despite the availability of appropriate information technology. Conceptual limits are discussed, including the continued reliance on relational database management systems; the use of free-text retrieval software is considered; and social limits are described, including access…

Describes a microcomputer-assisted method of using the commercial dBase III software package for the management of a personal bibliographic storage and retrieval system. This system provides users with a systematic way of keeping, for rapid retrieval, references to papers or documents previously read. (Author/CLB)
