Brown, Mary E. – Proceedings of the ASIS Annual Meeting, 1991
Addresses foundations of designing a bibliographic database for casual end-users, including the representation of knowledge, hierarchical schemata, cognitive processing of search problems, basic level categories of knowledge, and Boolean strategy in online searching. A hierarchical-based query model, data-item model, and idealized data model for…

Shepherd, Michael A.; Watters, Carolyn – Proceedings of the ASIS Mid-Year Meeting, 1992
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…

Lucarella, Dario; Zanzi, Antonella – Information Processing and Management, 1993
Discusses approaches to the integration of query-based information retrieval and browsing in a hypertext network. A prototype system developed to evaluate the proposed approach in terms of retrieval effectiveness and search efficiency is presented, and design and implementation issues concerning the prototype are considered. (30 references) (EA)

Hurt, C. D. – Information Processing & Management, 1998
Monotonic logic requires reexamination of the entire logic string when there is a contradiction. Nonmonotonic logic allows the user to withdraw conclusions in the face of contradiction without harm to the logic string, which has considerable application to the field of information searching. Artificial intelligence models and neural networks based…

Story, Roger E. – Information Processing & Management, 1996
Discussion of the use of Latent Semantic Indexing to determine relevancy in information retrieval focuses on statistical regression and Bayesian methods. Topics include keyword searching; a multiple regression model; how the regression model can aid search methods; and limitations of this approach, including complexity, linearity, and…

Taha, Ahmed – Journal of Library & Information Services In Distance Learning, 2005
The Web-based information and communication technology (w-ICT) has become a powerful means for delivery and dissemination of digitised information among the emerging virtual learning and business communities. The w-ICT has engendered a growing cybersphere paradigm to accommodate a huge mass of e-resources cast over the Web. Such abundance of…

Fidel, Raya – 1988
This study investigated online searching behavior manifested by 39 experienced professional searchers performing their regular, job-related searches in order to uncover the rules they use for the selection of search keys, and to represent these rules in a formal model that could be used in the construction of intermediary expert systems. The case…

Zipperer, W. C. – 1975
Two information dissemination centers at University of California at Los Angeles and University of Georgia studied the interactions between computer based search facilities and their users. The study, largely descriptive in nature, investigated the interaction processes between data base users and profile analysis or information specialists in…

Kantor, Paul B. – Journal of the American Society for Information Science, 1987
Examines a statistical model in which the users of an online system continually update their estimated probability of success, and quit or continue the search according to the expected utility of each action. The implications for search strategies are discussed. (Author/EM)

Belkin, Nicholas J.; And Others – Information Processing and Management, 1987
Based on an international workshop held at Rutgers University, this article discusses problems and issues in the design, research, and implementation of distributed expert-based information systems (DEBIS). Information needs of end users are stressed, architectures for expert information retrieval systems are explored, and prototype models are…

Cleveland, Donald B.; And Others – Journal of the American Society for Information Science, 1984
Relative effectiveness of indexing using full-text or less than full-text was tested using non-Boolean, chaining type of file structure and searching method. Indexing was done using titles, abstracts, full-text, references, and various combinations; Goffman's indirect method of information retrieval was used to structure and search file.…

Srinivasan, Padmini; Ruiz, Miguel E.; Lam, Wai – Proceedings of the ASIS Annual Meeting, 1996
Proposes a model that assists in understanding indexing on the World Wide Web and presents an experiment assessing the validity of Inverse Document Frequency (IDF) as a term weighting strategy for Web documents. Findings indicate that IDF scores are not stable in the heterogeneous and dynamic context of the Web. (Author/AEF)

Van Joolingen, Wouter R.; De Jong, Ton – Instructional Science, 1997
This article describes and tests a theory of scientific discovery learning based on the Scientific Discovery as Dual Search (SDDS) model. A study of 22 university chemistry students determined that conditions for performing a search operation in hypothesis space include sufficient knowledge of the search operation and reasons for choosing a…

Dilevko, Juris – Government Information Quarterly, 2002
Discusses the need for a new model for subject access to government information in academic libraries as a result of the growing influence of supranational organizations. Highlights include the World Trade Organization (WT); ruling under transnational economic agreements such as the North American Free Trade Agreement (NAFTA); private sector…

Wilson, T. D.; Ford, Nigel J.; Ellis, David; Foster, Allen E.; Spink, Amanda – Journal of the American Society for Information Science and Technology, 2002
Explores the relationship between the concept of uncertainty in information seeking within a model of the problem-solving process and variables derived from other models, based on longitudinal data collected in the United Sates and the United Kingdom that investigated the processes of mediated information retrieval searching during human…
