Describes the use of FAMULUS, a database management system, to teach library science students at Case Western Reserve University indexing, computerized file construction, and online information retrieval. The special features of FAMULUS and their use in course instruction are outlined and evaluated. A 19-item reference list is attached. (Author/JL)

Describes an automatic display system which has been developed for the editing of concept subnetworks within a relational index and which employs only a floppy diskette drive and a PET 2001 microcomputer. Appendices on Farradane's Nine Relations and on the Graphic Editing System Commands and a reference list are included. (Author/JL)

Describes XMARC, a set of computer programs which provides students with a simplified means of writing programs for the automatic indexing of an experimental collection of MARC records. (Author/FM)

Presents a computer-based system for generating thesauri from modulated subject-propositions (subject headings), which are structured according to facet analysis and augmented with appropriate codes for relating terms. Input to and operation of the system are described, as well as the programs developed. Fifteen references are listed. (Author/BK)

Following a discussion of derivative versus assignment indexing, use of roles, and concept behind Preserved Concept Indexing System, features of PERMDEX (microcomputer program to assist in creation of permuted printed index) are described including indexer input and prompts, the shunting algorithm, and sorting and printing routines. Fourteen…

Background, construction, and characteristics of a machine translation system developed in Germany and close to implementation are described. Among the characteristics are multilinguality, extendability, flexibility, modularity, and special features such as data structure, interface structure, and lexicon system. The broad range of applications is…

Describes an indexing technique based on overlapping word fragments as reference strings that are linked in a directed graph structure which makes possible exact match-, partial match-, and masked-partial match-retrieval and indicates search strategies for each case. Eight figures, two tables, and nine references are provided. (RBF)

Describes the organization of the House of Commons Library which provides information, documentation, and research services to its members and outlines the history of the Parliamentary On-Line Information System (POLIS). The physical description of POLIS, indexing practices, users, and the Library's subject thesaurus are discussed. Eight…

Describes technique for automatic book indexing requiring dictionary of terms with text strings that count as instances of term and text in form suitable for processing by text formatter. Results of experimental application to portion of book text are presented, including measures of precision and recall. Ten references are noted. (EJS)

Discusses future of online information retrieval systems in terms of types of computer hardware expected (noting size, memory, cost, microcomputers, peripherals); software expected; "user friendly" interfaces designed to enable users to search without special training; and new approaches to subject analysis and online searching.…
