Reviews the economic importance of applying computer technology to Chemical Abstracts Service database production from 1973 to 1983. Database building, technological applications for editorial processing (online editing, Author Index Manufacturing System), and benefits (increased staff productivity, reduced rate of increase of cost of services,…

Progress report on the Manitoba Education Information Access (MEDIA) project, a computerized educational information system. (DE)

Describes the local off-line data base at North Carolina State University, which is updated from OCLC archive tapes, and reviews the processing required to make this data useful for maintaining the data base and providing some ancillary services. (CWM)

In order to compare effects of input processing on information retrieval in three databases, 25 articles from a specific journal were examined. Tables and Venn diagrams show retrieval results from different manual and computer searches. The relation between document surrogates and subject matter of the documents is discussed. (SW)

A brief introduction to information retrieval by use of a variety of computer data bases including ERIC is presented. (JMF)

Presents a seven-step methodology for utilizing integrity constraint knowledge from heterogeneous databases. Describes generating a set of integrity constraints applicable at the integrated level from constraints specified on local databases. Introduces the concept of constraint-based relationships between objects in heterogeneous databases;…

Contends that large databases contain hidden knowledge, or literature that is logically linked but not bibliographically linked, that contains academically interesting commonalities not retrievable by normal searching methods. Based on search methods for discovering previously unknown causes of medical syndromes, a method for discovering new…

Proposes a structure for natural language descriptions of the semantic content of visual materials that requires descriptions to be (modified) keywords, phrases, or simple sentences, with components that are grammatical relations common to many languages. This structure makes it easy to implement a collection's descriptions as a relational…

This review of research and development work deals with activities specifically related to digital legal deposit. An overview of research activity in the various stages of the deposit process-particularly in digital preservation-follows. Building the infrastructure and pilot depositories are discussed. Issues that are not currently being addressed…

The vocational educational module of the Rhode Island Educational Management Information System is a data base that is an ongoing system that has been designed both to grow and to be modified to meet the needs of local and State administrators in the management of vocational education within Rhode Island.

This study examines the integration of heterogeneous bibliographic information resources from geographically distributed locations in an automated, unified, and controlled way using abstract data types called "classes" through the Message-Object Model defined in Smalltalk-80 software. The concept of achieving data consistency by…

As established within the framework of the UNISIST world science information system, the International Serials Data System (ISDS) is an international network of operational national and regional centers, jointly responsible for the creation and maintenance of computer based data banks, which contain essential information for the identification of…

In terms of examples drawn from clinical and research data files, one of the objectives of this study is to illustrate several factors that have combined to delay the implementation of medical data bases. A primary factor has been inherent in the design of computer software. The languages currently on the market are procedural in nature: they…

Words and word fragments from the computer-readable data bases "Chemical Abstracts Condensates" and "Biological Abstracts Previews" were analyzed in terms of length, number, and frequency of appearance to determine some parameters upon which inversion of these data bases could be predicated. Types (unique words or fragments)…
