Effective use of technology in areas that include admissions, record keeping, billing, compliance, athletic administration, and more hold untold potential to transform higher education by introducing significant efficiencies and dramatic cost reductions in serving students. How the institution organizes itself will to a large extent depend on how…

Discusses the potential of recent work in artificial intelligence, especially expert systems, for the development of more effective information retrieval systems. Highlights include the role of an expert bibliographic retrieval system and a prototype expert retrieval system, PROBIB-2, that uses MicroProlog to provide deductive reasoning…

Describes origin, development, and current state of Research Libraries Information Network's (RLIN) Command Analysis System, which digests large quantities of raw data on RLIN use and performance and produces useful graphs and reports. Recent results of system and pragmatic issues in analysis of online systems are noted. (7 references) (EJS)

Discusses technological developments causing changes in personal information systems: increase in commercial support services; proliferation of microcomputers; capability to download from secondary services into private files; and developing desire to utilize functions such as electronic mail and automated office functions. Appendices list 21…

Analysis of the searching behavior of human intermediaries revealed a routine for selection of search keys--free-text or controlled vocabulary--along a decision tree. Examples of decision rules demonstrate that these rules can be automated to significantly enhance the adaptability of intermediary expert systems. Eight sources are given. (EJS)

The objective of the unified database (UDB) program was to develop an automated information system that would be useful in the design, development, testing, and support of new Air Force aircraft weapon systems. Primary emphasis was on the development of: (1) a historical logistics data repository system to provide convenient and timely access to…

Presents data model based on text data model (TDM), universal relation model, and nonfirst normal form (NFNF) relations, and discusses applicability to text processing and document retrieval systems. Highlights include database technology applied to information retrieval, NFNF and universal relation, and TDM integration with NFNF universal…

The Hepatitis Knowledge Base (text of prototype information system) was used for modifying and testing "A Navigator of Natural Language Organized (Textual) Data" (ANNOD), a retrieval system which combines probabilistic, linguistic, and empirical means to rank individual paragraphs of full text for similarity to natural language queries…

Presents analysis of online search patterns within user searching sessions of National Library of Medicine ELHILL system and examines user search patterns on the CATLINE database. Data previously analyzed on MEDLINE database for same period is used to compare the performance parameters of different databases within the same information system.…

Suggests new method of external distribution called tree partitioning that involves use of binary tree to split incoming file into successively smaller partitions for internal sorting. Number of disc accesses during a tree-partitioning sort were calculated in simulation using files extracted from British National Bibliography catalog files. (19…

Examines two primary roles played by natural language processing in storage and retrieval of information and outlines organization of natural language interface for data retrieval (question-answering system) and approaches being taken to text analysis. Research issues in computational linguistics and interactive knowledge acquisition are…

Presents a formal model for specification of logical requirements of computer-based information systems that incorporates structural and dynamic aspects based on two separate models: the Logical Information Processing Structure and the Logical Information Processing Network. The model's role in systems development is discussed. (MBR)

Describes the methods and results of the transfer of the SCAN bibliographic database, sponsored by the Administration on Aging (AoA) to the private sector American Association of Retired Persons (AARP) when Congress repealed authority for AoA. Steps involved in the establishment of a bibliographic database are outlined. Four sources are given.…

This study investigated the efficacy of utilizing comprehensive database search strategies in performing an online literature search in the subject area of psychology, with special interest in the performance of the database PsycInfo. The DIALOG Information Retrieval Service's DIALINDEX subject category options were used as the major search…

Assesses the promotion and development of online information retrieval in China. Highlights include opening of the first online retrieval center at China Overseas Building Development Company Limited; establishment and activities of a cooperative network; online retrieval seminars; telecommunication lines and terminal installations; and problems…
