The LABLIB system at the Language Centre of the University of Turku, Finland, is described. LABLIB is a computerized bilingual information retrieval system that assumes a minimum of user computer expertise and includes comprehensive information on tape recordings, video programs, and other teaching materials.

The current state of information retrieval (IR) evaluation is reviewed with criticisms directed at the available test collections and the research and evaluation methodologies used, including precision and recall rates for online searches and laboratory tests not including real users. Automatic text retrieval systems are also discussed. (32…

Reports on a study that analyzed 3,746 papers obtained from retrospective searches of the Medline database according to language, length of abstract, depth of indexing, and inclusion of author's address. The focus is on scientific production in Slavonic countries and the information value of Slavonic papers in Medline. (10 references) (MES)

Characterizes information retrieval systems in a network environment from a user's perspective along two axes: query and presentation. Several examples of early, current, and developing information retrieval systems are considered within this framework, and Daltext, a prototype system to support research on text-based retrieval systems, is…

This discussion of educational applications of user interfaces covers the benefits of adopting database techniques in organizing multimedia materials; the evolution of user interface technology, including teletype interfaces, analogic overlay graphics, window interfaces, and adaptive systems; application design problems, including the…

Discusses the history and structure of the online database of the second edition of the Oxford English Dictionary (OED) and the software tools developed at the University of Waterloo to manipulate the unusually complex database. Four sample searches that indicate some types of problems that might be encountered are appended. (DB)

Describes the procedures followed in inventorying, cataloging, and barcoding government documents records from Government Printing Office (GPO) tapes as part of an integrated online system with Bryn Mawr, Haverford, and Swarthmore College libraries. The use of a vendor to help with retrospective cataloging is also described. (nine references) (LRW)

Analyzes the properties of genetic sequences that cause the failure of classical algorithms used for data compression. A lossless algorithm, which compresses the information contained in DNA and RNA sequences by detecting regularities such as palindromes, is presented. This algorithm combines substitutional and statistical methods and appears to…

Computerized bus-routing systems plot the most efficient routes, cut the time it takes to draw routes, and generate reports quickly and accurately. However, school districts often underestimate the amount of work necessary to get information into the computer database. (MLF)

Applies theories about organizational information processing to better understand the influences on method of access and on effects of using online information. Explores the extent to which organizational differences also influence these variables, what the positive and negative outcomes from using online commercial databases are, and how those…

Conversion of government publication records from an existing machine-readable file using the CODOC format resulted in fewer data entry revisions and the overcoming of three obstacles: incompatible database record formats, reformatting of all CODOC files, and addition of diacritics to CODOC files. Methodology and techniques are discussed for other…

A profile of information technologies in secondary schools developed through interviews with 66 business educators found that word processing, database management, and spreadsheets are most frequently taught. Most respondents felt that the business education department should be in charge of teaching such technologies. (SK)

Describes a study of professional searchers that investigated their decisions about using search terms. The use of descriptors from a controlled vocabulary versus the use of textwords for free-text searching is examined, searching styles and differences in subject areas are discussed, and the quality of thesauri and indexing is considered. (six…

Proposes that methods intended to assist in information retrieval be grouped together and that the group be called "informed retrieval," a process which uses feedback from an information system to improve retrieval results. It is suggested that an integrated framework be developed that includes authority control and informed retrieval as…

Describes a computer system in which art reproductions are described and entered into a database containing 27 categories of information. Named the Visual Art Index System (VIAS), its underlying structure is influenced by contemporary models of aesthetics and art criticism. Maintains that the database and laserdisk can effect teaching methodology,…
