The need for a coherent information systems development strategy that integrates both voice and data communications with computing into the campus computing environment is described. The need for a strategy, as opposed to a set of goals, in light of rapidly changing technological parameters, is discussed. (MLW)

Discusses on-demand publishing as a solution to the information explosion and cites ERIC, which specializes in unpublished materials, as a model for such a solution. Topics covered include role and functions of scholarly publishing (selection and dissemination), fractional publishing, service publishing, and scholarly journals. Eleven sources are…

Proposes split model for index term distribution in document set that uses rank function for high frequency terms and size function for low frequency terms; the point of transition is determined either empirically or by rule. Distributions to describe index term exhaustivity and term co-occurrence are considered briefly. (36 references) (EJS)

This report presents an analysis blueprint for data provided by the National Education Longitudinal Study of 1988 (NELS:88), a survey system sponsored by the National Center for Education Statistics (NCES). The report will inform beginning NELS:88 data users of the many substantive issues that can be addressed by the data, and it should present…

Discusses a model telephone reference service focusing on the application of library experience to the design of an online system. The inclusion of current ready reference materials in the database of future automated systems is suggested, and 11 references are listed. (RAA)

Presents a situated based computer-assisted language learning system named VIDYA. The principles discussed include use of mastery learning in the situated learning context, student modeling of language constructs, dynamic courseware presentation and a generic courseware evaluation technique. Summarizes the present status of VIDYA. (24 references)…

Presents a new model of searching in online and other information systems, and reviews the literature of manual information seeking behavior for suggestions of capabilities users might like in online systems. Based on the model--called "berrypicking"--and research, suggestions are made for how new search capabilities could be implemented…

Presents a model for the a priori analysis of natural language queries which uses an algorithm to transform the query into a logical pattern that is used to determine the answerability of the query. The results of testing by a prototype system implemented in PROLOG are discussed. (20 references) (CLB)

Describes a model for the workload of a full text retrieval system and of a simulation model for a version of an existing system called Full/Text. The effectiveness of various data caching strategies using the 2 models are explored, and the impact of various parameters on the strategies are evaluated. (13 references) (LRW)

Describes a model that displays structures necessary to map between the conceptual and external levels in database management systems, using an algorithm that maps the syntactic representations of tuples onto semantic representations. A technique for translating tuples into natural language sentences is introduced, and a system implemented in…

Reviews literature on environmental information since 1986, with special emphasis on machine-readable sources as reported in the published literature. Highlights include a new model for studying environmental issues; environmental communication studies, including user studies; and environmental information sources, including pollution media and…

Discusses the problems of compressing a large textual database for storage on CD-ROM. A text-compression algorithm is presented, new algorithms for compression of indices are described, and the ARTFL (American and French Research on the Treasury of the French Language) database is used as an example. (14 references) (LRW)

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)

Discusses the actual and potential impact of local shared automated library systems on the development of a comprehensive nationwide bibliographic database (NBD). Shared local automated systems are described; four local shared automated system models are compared; and the current interface between local shared automated library systems and the NBD…

Discussion of relevance and the needs of the users in information retrieval focuses on a deductive object-oriented approach and suggests eight inference rules for the deduction. Highlights include characteristics of a deductive object-oriented system, database and data modeling language, implementation, and user interface. (Contains 24…
