Three aspects of training and education for online searching of bibliographic and databases are addressed: (1) the present status--what is being taught, (2) a proposed model--what needs to be taught, and (3) the implementation of the model--who should teach what. The first section shows which organizations (library and information schools,…

Computer based information search services, ISS's, of the type that provide on-line literature searches are analyzed from a system's viewpoint using a continuous simulation model. The analysis shows that the observed growth and stagnation of a typical ISS can be explained as a natural consequence of market responses to the service together with a…

Describes a relational data model that can be used for knowledge representation and manipulation in rule-based medical consultation systems. Fuzzy queries or attribute values and fuzzy set theory are discussed, functional dependencies are described, and an example is presented of a system for diagnosing causes of eye inflammation. (15 references)…

With reference to the "BIOSIS Previews" magnetic tape service of BioSciences Information Service (BIOSIS), marketing patterns of on-line bibliographic products are examined and future possibilities are discussed, with emphasis on geographic distribution of usage, organizations and institutions employing on-line service, and their…

Describes the meaning of the term multimedia database and presents a model of its potential role in aiding message creation for the purposes of communicating educational material using many parallel channels. Some of the problems associated with the implementation of such systems are outlined. Seventeen references are listed. (Author/LLS)

Discusses new pricing models for some online services and considers the possibilities for the traditional online database market. Topics include multimedia music databases, including copyright implications; other retail-oriented databases; and paying for free databases with advertising. (LRW)

Discusses a model telephone reference service focusing on the application of library experience to the design of an online system. The inclusion of current ready reference materials in the database of future automated systems is suggested, and 11 references are listed. (RAA)

This self-improvement manual developed for experienced online searchers presents and discusses several alternative search strategies and their appropriate use to achieve the desired outcome. The manual is divided into two parts: (1) an eight step model of the total search process emphasizing how the decision of the information professional affects…

Describes evolution of an in-house database search service developed by University of British Columbia's Educational Research Services and Computing Center. The tryout phase in developing a model for downloading citations to serve end users as a beginning nucleus for use in microcomputer accessed personal information systems is highlighted. (MBR)

This study conducted to determine representation impact on information items retrieval in terms of precision and recall performance and overlap used the INSPEC "Computers and Control Abstracts" loaded on DIATOM, an online retrieval system based on DIALOG, as the database to be searched. Sixty-nine users provided 84 queries which were…

Revised to reflect changes in both DIALOG and ERIC, this second edition of a self-improvement manual for online searchers who wish to refine their skills presents three basic approaches to searching and provides illustrations from DIALOG's ERIC ONTAP database. The manual is divided into two parts: an 8-step model of the total search process which…

The Hepatitis Knowledge Base (text of prototype information system) was used for modifying and testing "A Navigator of Natural Language Organized (Textual) Data" (ANNOD), a retrieval system which combines probabilistic, linguistic, and empirical means to rank individual paragraphs of full text for similarity to natural language queries…

The National Academy of Sciences suggests models for biomedical research which include a biology-wide information system with computerized database accessible from a multitude of dimensions. Links could help discover whether toxic chemicals have effects similar to hormones. Commonalities from molecules to ecosystems might restructure available…

Finding that the promotion of a national information industry can best be pursued through the planning and establishment of a national teledocumentation network, this study (based on the experiences of Spain) offers a model that may be of interest to UNESCO (United Nations Educational, Scientific and Cultural Organization) member states wishing to…

This paper reports on an application of parallel models to the area of information retrieval and argues that massively parallel, distributed models of computation, called connectionist, or parallel distributed processing (PDP) models, offer a new approach to the representation and manipulation of knowledge. Although this document focuses on…
