Librarians must become skilled in the language and techniques of computer systems and data management in order to administer large machine readable files of information. An annotated bibliography for a self-education program is appended. (Author/AB)

Virtual scatter storage schemes are well suited dictionaries, having both rapid lookup and economy of storage. (MF)

A distinction is made between cost-effectiveness analysis and cost-benefits analysis as applied to information systems; and the relationship between costs, performance, and benefits is discussed. (Author)

Describes the six tasks required in the development of an online database: analysis, design, programing, testing, loading, and documentation. Figures illustrate file formats, and a bibliography lists five sources. (FM)

Compares the cost and retrieval effectiveness of three online information services when searching is conducted primarily on one database. The costs of searching, profile storage, printing, document delivery, surcharges, and updates are identified for WISE, BRS, and DIALOG. (FM)

The method of handling the printed documentation associated with online information retrieval, which is described, involves the use of a series of separate but related files: database files, system files, network files, index sheets, and equipment files. (FM)

Concentrates on the practical, everyday aspects of online search strategy, specifically offering ideas and comments on search strategies for STAIRS users. Included are tables listing the logical operators available on the system and the search level (document, paragraph, sentence, word) of each. (Author/JD)

Addresses the problem of systematic biases which affect the way that individuals construct and modify search queries on online retrieval systems, and suggests a searching algorithm that helps to avoid the effect of those biases. (FM)

Describes the design and development of the Reference Librarian Enhancement System (REFLES), a microcomputer based system for in-house data files. The REFLES prototype is described in its test form, followed by presentation of the working environment, problems, and evaluation of the current version. Future possibilities of REFLES are also…

Ordered sets (OS) of documents are encountered more and more in information distribution systems, such as information retrieval systems. Classical similarity measures for ordinary sets of documents need to be extended to these ordered sets. This is done in this article using fuzzy set techniques. The practical usability of the OS-measures is…

Examines early and current approaches to automatic thesaurus construction and describes an approach to automatic generation of global thesauri based on the term discrimination value model and on an appropriate clustering algorithm. Preliminary results of implementation of the method are reported. (46 references) (Author/MES)

Presents two partitioning methods for signature files and a method of fast weight computation to implement a document ranking strategy. Storage requirements, number of disk accesses, and processing time for these methods are compared with two other access methods. Merits of the partitioning methods are summarized. (20 references) (MES)

Educational development requires management, which is basically decision-making based upon information. Information must be processed, involving movement from its source, analysis, transmission, storage, retrieval, summarization, transformation, and reporting. The regulation of this process is the purview of the information management system…

A model is proposed to explain the retrieval characteristics of an information retrieval system. (Author)
