This article provides an overview of over 100 years of social science research on deception and lying. The aim is to raise awareness on the full scope of research findings on deception and lying to help the scientific community to communicate these research findings to practitioners who assess the veracity of individuals statements, further future…

This article provides an overview of and rationale for the use of authority in school libraries--from both an historical and current/future perspective. First, the importance of consistent, meaningful authority term context and form is discussed. Then, the exciting, yet challenging, role of authority in today's information world is…

From 1992 to 1995 the IFLA Study Group on Functional Requirements for Bibliographic Records (FRBR) developed an entity relationship model as a generalised view of the bibliographic universe, intended to be independent of any cataloguing code or implementation. The FRBR report itself includes a description of the conceptual model (the entities,…

Discussion of the classification of documents from bibliographic databases focuses on a method of vectorizing reference documents from LISA (Library and Information Science Abstracts) which permits their topological organization using Kohonen's algorithm. Analyzes possibilities of this type of neural network with respect to the development of…

The link between classification and knowledge is explored. The strengths and limitations of four classificatory approaches (hierarchies, trees, paradigms, and faceted analysis) are described in terms of their ability to reflect, discover, and create new knowledge. Examples are provided of the way in which knowledge and the classification process…

Describes the development and functions of a text retrieval program that makes extensive use of the best match model of document retrieval rather than the Boolean model. The use of the program in teaching and research at the University of Sheffield is summarized. (24 references) (CLB)

Examines problems encountered when setting up a hypertext link, called an identity link, for moving between bibliographic and full text databases. MEDLINE and CCML (Comprehensive Core Medical Library) are used as examples, BRS/SEARCH text retrieval software is explained, and problems with syntax are discussed. (two references) (LRW)

Presents a general overview of the development of Information Science Abstracts. The historical perspective, including the contributions of individuals and institutions, is discussed; its coverage is compared with that of other information science databases; and retrieval capabilities are described. (four references) (Author/CLB)

Describes methods for applying natural-language processing for automatic concept-based indexing of full text and methods for exploiting the structure and hierarchy of full-text documents to a large collection of full-text documents drawn from the Health Services/Technology Assessment Text database at the National Library of Medicine. Examines how…

Presents a method for extracting maximal frequent sequences in a set of documents. A maximal frequent sequence is a sequence of words that is frequent in the document collection and is not contained in any other longer frequent sequence. Frequent maximal sequences can be used as content descriptors for documents. (MES)

Presents the conceptual design of a full-scale bibliographic database that includes bibliographic, authority, holdings, and classification data and is based on entity-relationship modeling. MARC format, AACR2 (Anglo-American Cataloging Rules) compatibility, and normalization and efficiency are discussed. (Author/LRW)

A hierarchical extension to the American National Standard for Bibliographic Information Interchange on Magnetic Tape is defined and described. The accommodation of the extension within the existing standard is discussed, modifications to the existing standard are proposed, and applications of the hierarchical format are presented. (21 references)…

Online bibliographic and network-based information systems are starting to blur the boundaries that separated print documents. Two concepts emerge as a consequence: the union record, an entity that combines multiple catalog records for a single bibliographic item; and an information dossier, a hypertext-like information object built by linking…

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…

Applies a prefix trie index, or trie hashing, to the problem of providing fast search times, fast load times, and fast update properties in a bibliographic or full-text retrieval system with inverted files. Statistics are given for a test database consisting of an online catalog at the University of Western Ontario. (Author/LRW)
