Compares two natural language processing search engines, WIN (WESTLAW Is Natural) and FREESTYLE, developed by LEXIS. Legal issues in natural language queries were presented to identical libraries in both systems. Results showed that the editorials enhanced relevance; a search would be more thorough using both databases; and if only one system were…

Discusses the relationship between personal knowledge in a domain and online searching proficiency in that domain, and the relationship between searching proficiency and database-assisted problem-solving performance based on a study of medical students. Search results, selection of terms, and efficiency were found to be related to problem-solving…

Discusses readers' advisory services in public libraries and describes a method to convert information on specific books and genres to a computer database. Topics include utilizing staff knowledge, fields included for each book, the development of descriptors, the editing process, and writing summaries and critiques of the books. (LRW)

Discussion of hypertext and its uses in the learning process focuses on an experiment in which undergraduate students used hypertext for computer-based learning about databases. Results of a survey of students which explored when and how they used the hypertext, for what purpose, and the types of searching they preferred are reported. (12…

Describes a project at the University of Sheffield that is investigating the use of nearest-neighbor retrieval algorithms for full-text searching. Nearest-neighbor searching is compared with Boolean retrieval and hypertext, and an experimental text retrieval system called INSTRUCT (Interactive System for Teaching Retrieval Using Computational…

Describes the development of a computer-aided decision-making system to assist educational practitioners in curriculum decision making about innovative program features and implementation requirements. Topics discussed include the identification of variables; database generation; mathematical modeling; compromising between effectiveness and…

Describes how to use the Internet to access commercial online database services, such as DIALOG, and discusses the advantages in terms of costs, reference services, and accessibility. Outlines in detail how to save a search session or link another terminal to a Telnet session, and provides information and Internet addresses for eight vendor…

This article briefly describes the development of bibliographic retrieval systems in the Instituto de Beneficio di Minerales (IN BE MI) in Salta, Argentina, using the Mini-micro CDS/ISIS software developed by Unesco. (LRW)

Discusses the generalized inverse Gaussian-Poisson (GIGP) process for informetric modeling. Negative binomial distribution is discussed, construction of the GIGP process is explained, zero-truncated GIGP is considered, and applications of the process with journals, library circulation statistics, and database index terms are described. (50…

Reviews changes in the ERIC database on compact disk that have been made in systems offered by the following vendors: Dialog, SilverPlatter, and OCLC. Highlights include system requirements, costs, search strategies, printing, help screens, tutorials, double posting, available formats, display of search results, and searchable fields. (LRW)

Examines materials about laserdisks in literature published between 1970 and 1989 that addresses library applications. Searches on ERIC, Information Science Abstracts, Library and Information Science Abstracts, and Library Literature are reviewed; core laserdisk journals are discussed; indexing overlap is examined; and other online databases are…

The Machine Readable Collections Reading Room of the Library of Congress is described with an emphasis on the reference assistance required and how it compares with assistance required in other areas of the Library of Congress. The interaction between users and librarians is shown to be like that of bibliographic instruction. (EAM)

Discussion of discourse created by computers defines discourse as a pattern of cognitive functioning and identifies two such modes of thought: narrative and expository. Discussion covers the computer as discourse; schemas as a way to understand how knowledge is organized; simulations, hypermedia, and databases as discourse; and interactive…

Describes an image database system assembled using separate computer components that was developed to overcome text-only computer hardware storage and retrieval limitations for a pavement design class. (JJK)

Discusses "REFLEX," a software package for scheduling. Explores the program's applications in preparing a departmental class schedule. Explains that "REFLEX" includes a filter function and some attributes of a spreadsheet but lacks the ability to interact with other databases. Concludes that the program can make scheduling…
