Discussion of the failure of individual keywords to identify conceptual content of documents in retrieval systems highlights Metric Similarity Modeling, a method for creating vector space representation of documents based on modeling target interdocument similarity values. Semantic relatedness, latent semantic indexing, an indexing and retrieval…

Reports on a theoretical model of structured document indexing and retrieval based on the Dempster-Shafer Theory of Evidence. Highlights include passage retrieval, hypertext, relevance, information needs, implementation of the model, an evaluation scheme designed to test the model's effectiveness, and results of experiments that investigated…

Reviews different structures and techniques of knowledge representation: structure of database records and files, data structures in computer programming, syntatic and semantic structure of natural language, knowledge representation in artificial intelligence, and models of human memory. A prototype expert system that makes use of some of these…

Presents costs and benefits of document information systems as well as a design methodology. Highlights include the method of working, method of modelling, multiple data types, access structure and indexing, and a case study of the implementation of a document information system in the Netherlands. (Author/LRW)

Describes the development of a software system, SIMPR (Structured Information Management: Processing and Retrieval), that will process documents by indexing them and classifying their subjects. Topics discussed include information storage and retrieval, file inversion techniques, modelling the user, natural language searching, automatic indexing,…

Describes the Belief Function Model for automatic indexing and ranking of documents which is based on a controlled vocabulary and on term frequencies in each document. Belief Function Theory is explained, and the Belief Function Model is compared to the Standard Vector Space Model. (17 references) (LRW)

Describes a model for the standardization of names in bibliographic databases. Discusses a prototype that was developed to demonstrate feasibility of the model, and investigates the impact of implementing the model. Findings suggested that the new model will revolutionize name authority control and that the prototype verifies the technical…

Describes the development and outcome of a cooperative computerization effort involving nine public and university museums. The discussion covers the project goals, data development and analysis, and contributions resulting form the project. Appendices provide the system data fields used and a comparison between automation of library and museum…

RESULTS ARE REPORTED OF A STUDY OF THE FEASIBILITY OF A NATIONAL ADULT EDUCATION INFORMATION CENTER, IN WHICH IT WAS PROPOSED TO (1) STUDY INFORMATION PROBLEMS AND RESOURCES IN ADULT EDUCATION AND RECOMMEND NEW SERVICES WHICH WOULD BE MOST USEFUL TO THE FIELD , (2) DEVELOP THE TOOLS OF SUBJECT ANALYSIS WHICH WOULD BE NEEDED IN THESE SERVICES, AND…

E-learning leads to evolutions in the way of designing a course. Diffused through the web, the course content cannot be the direct transcription of a face to face course content. A course can be seen as an organization in which different actors are involved. These actors produce documents, information and knowledge that they often share. We…
