Reports results of two-phase study of size and composition of U.S. online database production organizations. Comparison of 1982 and 1984 data for online database producers to determine number of personnel employed in intellectual production of databases permitted identification of employment trends, which forms focus of discussion.

This first article of a three-part series provides an overview of the record format, organization, and coverage of two databanks providing legal information. Tables cover record segments and fields and inclusion of information from federal libraries, state cases, United Kingdom and French law libraries, and additional libraries and services. (EJS)

Online seaches of sample topics in the area of forensic medicine were conducted in the following life science databases: Biosis Previews, Excerpta Medica, Medline, Scisearch, and Chemical Abstracts Search. Search outputs analyzed according to criteria of recall, uniqueness, overlap, and utility reveal the need for a cross-database approach to…

Several technical issues related to the Schools and Staffing Survey (SASS) were studied. The 1990-91 SASS is a set of four inter-related surveys of public and private elementary and secondary schools, districts, teachers, and administrators conducted by the National Center for Education Statistics (NCES). Preliminary analysis of the 1990-91 SASS…

The Ministry of Agriculture, Fisheries and Food conducted an operational evaluation of the software packages CAIRS and STATUS, which were used to build databases and databanks. Setting up the trial, types of data involved (chemical products used as pesticides), searching and presentation of data, and the final choice are covered. (EJS)

Five models which perform search tasks of the Data Base Access and Search Environment (DBASE) are presented and used for comparison with subject search performance--unconstrained (rule-based, decision theoretic) and constrained (optimal rule-based, rule-based, probabilistic rule-based). Previous experiments and the modeling approach are briefly…

Provides background of automatic indexing and overview of Fully Automatic Syntactically based Indexing of Text (FASIT), a system based on idea that content-bearing words belong to certain syntactic categories. Results of comparison of FASIT with thesaurus and stem-based indexing systems on database of 250 documents and 22 queries are summarized.…

Compares 48 features of four versions of the ERIC database, two commercial (SilverPlatter, FirstSearch) and two free (AskERIC.org, SeachERIC.org), to determine whether features of the commercial versions were worth the cost to academic libraries. Reports results of a survey that investigated user preferences, and concludes that value added…

Analyzes the extensive use of personal examples and stories in the academic essays of students who are nonnative speakers of English. Draws on a large database of college examination essays to compare the use of personal examples in essays written by native and nonnative speakers. Finds nonnative students not only use examples more often than…

Reviews the implementation of an experimental project in the Pan American Health Organization to disseminate health related information via CD-ROM in Latin America and the Caribbean, and compares the costs and relative advantages of information delivery using online retrieval systems and CD-ROM systems in developing countries. (four references)…

Evaluates four map products currently available on CD-ROM in terms of hardware requirements, ease of installation, software, product content, documentation, cost, and instructional materials. Conclusions about the current status of maps on CD-ROM are offered and the desired characteristics for a perfect CD-ROM mapping product are identified. An…

Discusses previous research that examined the effects of different kinds of vocabulary control on retrieval effectiveness, and describes a study that addressed the effects of indexing depth on standard retrieval evaluation measures in the context of a typical commercial retrieval system. It is concluded that controlled vocabularies affect…

Discusses the results of modeling the performance of searching large text databases via various parallel hardware architectures and search algorithms. The performance under load and the cost of each configuration are compared, and a common search workload used in the modeling is described. (Contains 26 references.) (LRW)

Describes the nature of intellectual access to digitized art images using qualitative methodologies based on a study at the University of Central Florida. Queries of art historians are analyzed and compared to retrieval parameters and image characteristics, and implications for database design are suggested. (Author/LRW)

Reports on the use of stemming for Slovene language documents and queries in free-text retrieval systems and demonstrates that an appropriate stemming algorithm results in an increase in retrieval effectiveness when compared with nonstemming processing. A comparison is made with stemming of English versions of the same documents and queries. (24…
