In this paper, we propose a syntax-based text retrieval system for on-line language learning and use a fast regular expression search engine as its main component. Regular expression searches provide more scalable querying and search results than keyword-based searches. However, without a well-designed index scheme, the execution time of regular…

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)

Notes applications of information technology in archival activity, highlighting computer use in management of records centers and archives, intellectual control including computer indexing and online retrieval, and preservation of machine-readable records. Cooperative development of archival systems and impact of mini- and microcomputers are…

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)

This examination of abstracting-indexing services for the field of history focuses on Historical Abstracts (HA) and America--History and Life (AHL), and their relationship to the American Bibliographical Center's Subject Profile Index (ABC-SPIndex). The history, scope, selection criteria, and classification arrangements of the two databases are…

The report is concerned with the implementation of an on-line information storage and retrieval system for the Rome Air Development Center. This system is to incorporate techniques of automatic document classification for a large document collection in an interactive environment. Following a review of the system design, the implementation of the…

The paper reports on a series of programs that have been developed at the Moore School to process data-bases, consisting of textual items, and to index and arrange the data items in accordance with an automatically generated classification system. The programs produce the directories and the rearranged data-base on microfilm, where it may be…

Surveys the current state of minicomputer-operated information systems capable of incorporating linguistic features, focusing on the Minicomputer Operated Retrieval (Partially Heuristic) System. Consideration is given to the automation of the indexing process and to available search strategies. (FM)

Presents principles for determining profile of a system user based on analysis of co-occurrence of index terms in queries and pertinent documents. A procedure for determining index term weights, the information value of which depends on the degree of homogeneity of system users, is introduced. Three references are cited. (EJS)

Based on a series of studies performed by ERIC/Information Resources staff and consultants which focused on the activities of over 40 experienced online searchers, this report offers the following suggestions for enhancing certain online retrieval system features and making improvements in ERIC vocabulary: (1) the implementation of an online…

SOLAR is an interactive Storage and On-Line Automatic Retrieval system which is operational at Washington State University. It can run continuously with virtually any mix of tasks in a general purpose computing environment. (22 references) (Author)

Examines the development and current status of research on personal information systems, i.e., those systems where an individual collects, annotates, and stores bibliographic information according to his own needs and preferences. Effects of computer-based dissemination services on the growth and management of these systems are discussed. Included…

Contained in this report are the results of the second phase (July, 1968 - June, 1970) of the File Organization Project, directed toward the development of a facility in which the many issues relating to the organization and search of bibliographic records in on-line computer environments could be studied. The papers in this volume deal…

Describes use of a database management system (dBASE II, produced by Ashton-Tate), noting best features and disadvantages. Highlights include data entry, multiple access points available, training requirements, use of dBASE for a bibliographic application, auxiliary software, and dBASE updates. Sample searches, auxiliary programs, and requirements…

A series of experiments determined whether thesauri enhance the retrieval of Chinese documents and automatic indexing can compete with manual indexing in a Chinese information retrieval system (CIRS). Statistical analysis of recall and precision measures suggest that relational thesauri do improve retrieval and that automatic indexing is…
