Describes a dialog-program which uses basic statements available on a WANG 2200T version connected to a floppy-diskette to cross-reference a given set of keywords, author names, journal names, and specified reference numbers. Special program features are described and two references are listed. (Author/RBF)

Investigates applicability of inverted file processing in magnetic bubble memories by presenting four magnetic bubble memory models as storage mediums: one based on a major-minor loop configuration; one utilizing a decoder design on a magnetic bubble memory chip; and two based on different structural configurations of the first two. (MBR)

The structure of a retrospective information retrieval system that uses equifrequent word or text fragments is described, and its advantages over word oriented systems are mentioned briefly. (Author)

Four advantages of storing and retrieving geometric figures and chromosome images through the use of shape-oriented similarity measures are presented. (Author)

False drops occur in a system of random superimposed coding for edge-notched, punched, and feature cards. Formulae for the false dropping fraction are derived, and figures and tables are given for the calculated values in the most popular scheme. (Author/LS)

A new method for concentrating keywords of a thesaurus, based on a mathematical study of the distribution of characters in a defined natural language. (Author/KP)

Introduces two distribution schemes that partition documents over multiple processors and the corresponding multiprocessor retrieval algorithms that match relevant documents to user queries. The suggested framework is based on a general purpose hypercube multicomputer architecture with a dedicated disk for each node. A timing analysis for the…

Demonstrates that hierarchical naming schemes--one with a single namespace and fixed root spread over all machines in a distributed system, and a second with total namespace composed of some aggregation of individual namespaces of each component system's filestores--can coexist in distributed computer systems. Combined system's design is…

Describes an online library catalog in which bibliographic references have been compiled by simply transcribing the descriptive data found on the title page and elsewhere on the documents, and discusses the wider implications of the use of natural language descriptions without modifications. Eleven references are listed. (FM)

Presents uniform and efficient approach for processing all truncated query terms in information retrieval which requires one disk access to obtain from the permuted dictionary all strings represented by truncated term. The problem of the overhead storage required to implement the permuted dictionary is discussed. Fifteen references are provided.…

This content analysis of library and information science (LIS) research from 1965 to 1985 was conducted to determine the distribution of topics in research articles and the research methodologies that have been used. Results indicated that information storage and retrieval was the most popular topic and that empirical strategies predominated. (20…

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 data model role in an office filing facility, office data model requirements, and various modelling paradigms for office data modelling. Data model application to a typical collection of office data is presented, filing and retrieval operations are illustrated, and proposed research into other office data modelling aspects is outlined.…

Examines the selective dissemination of indexed surrogates to overcome two major causes of cultural lag: reading overload and lack of cogency of technical communication. An analysis of three models--reference-retrieval systems, question-answering systems, and surrogate-dissemination systems--explores reasons for lag in technique implementation.…

Reviews the special requirements of a bibliographic database, and shows how they are met in the DOBIS-LIBIS (Dortmund Library System-Leuven Library System) system. Full authority file control over the indexes to the database is discussed, and the DOBIS-LIBIS system is described in detail. References are included. (Author/BK)
