Discusses a method for organizing and augmenting the data in a complex database to make automatic retrieval possible. Presents an example of the method using a database of information on the nature and use of fungicides. Initial results of trials with potential users suggest that the system can produce relevant responses to queries. (Author/AEF)

Proposes an extended vector-processing scheme that extracts information from hypertext links to enhance retrieval effectiveness. Evaluates the impact of bibliographic references, bibliographic coupling, cocitation and document representative relationships. Shows that hypertext links do not always improve average precision, and interdocument…

Discusses the role of the information specialist as an intermediary and how each selection made in the process of providing information involves a value judgment. Topics include censorship, self-knowledge and censorship, censorship in the wider community, professional response to the demands of censorship and ethics issues, and academic…

Effective notetaking in student research consists of three steps: identification of key-word and related words in the researchable questions, skimming and scanning, and extracting needed information. These steps begin after students have defined and narrowed the task, constructed researchable questions, and located appropriate sources. Two…

Describes the development of a Unified Medical Language System (UMLS) by the National Library of Medicine that will retrieve and integrate information from a variety of information resources. Highlights include the metathesaurus; the UMLS semantic network; semantic locality; information sources map; evaluation of the metathesaurus; future…

Discusses intelligent software agents, or knowledge robots (knowbots), and the impact they have on the Internet. Topics addressed include ethical dilemmas; problems created by rapid growth on the Internet; new technologies that are amplifying growth; and a shift to a market economy and resulting costs. (LRW)

This research reports an algorithmic approach to the automatic generation of thesauri for electronic community systems. The techniques used include term filtering, automatic indexing, and cluster analysis. The Worm Community System, used by molecular biologists studying the nematode worm C. elegans, was used as the testbed for this research.…

Describes the use of the Z39.50 information retrieval protocol as the basis for Infocal, a read-only, client/server-based campus information system. Technical considerations in adapting the protocol to nonbibliographic data, including semantic modules, dynamic attribute sets, and dynamic record syntax, are described in detail. (Contains 11…

Describes an approach to electronic document delivery which has evolved at Tilburg University (Netherlands), leading to the development of a system called Ariadne. Highlights include various generations of electronic document delivery systems; standards, including the work of the Group on Electronic Document Interchange; and a description of the…

This last article in a series which reported results of a software evaluation project done by the Netherlands Association of Users of Online Information Systems (VOGIN) focuses on how to select appropriate software. Topics discussed include price considerations; user needs; and types and quality of information. (Contains 11 references.) (LRW)

Examination of citations indexed in Social Science Citation Index (SSCI) reveals salient patterns which can be helpful in determining interdisciplinarity and/or disciplinarity. Collection development efforts can be enhanced by examination of citation patterns of published research related to a classical social science author such as Jean-Jacques…

The relationships of task complexity, necessary information types, information channels and sources are analyzed at the task level on the basis of a qualitative investigation. Data were collected in a public administration setting, and the findings indicate systematic and logical relationships among the factors analyzed. (54 references)…

Innovative training technologies are increasing, but many professional/technical staff do not attend. The corporate classroom of the future is the workplace, and computer networks will be the major source of information and training. Teaching people how to learn and improving information retrieval systems are the greatest challenges. (SK)

An online library catalog was used to evaluate an interactive query expansion facility based on relevance feedback for the Okapi, probabilistic, term weighting, retrieval system. A graphical user interface allowed searchers to select candidate terms extracted from relevant retrieved items to reformulate queries. Results suggested that the…

Describes several projects that integrate the Internet and specific Internet resources into undergraduate teaching and learning. Problems are discussed, including trying to retrieve specific and useful information, questions of reliability and accuracy of information, the need to become more user friendly, and demands on libraries for training and…
