Describes a study that was conducted to model the navigation patterns followed by users when retrieving information in hypertext systems. The development of two frequency distribution models is explained, the influence of search tasks on path patterns is discussed, and further research is described. (Contains 17 references.) (LRW)

Develops a mathematical model for fitting the retrieval runs in the TREC-6 (Sixth Text REtrieval Conference) ad hoc retrieval exercise to explore how the depth of the pool of relevance judgments made for each run affects performance scores. Concurs that even on the basis of analyses of individual systems, the pool depth of 100 used by TREC is…

Describes the process one women went through to find a job in another part of the United States. Tips on job-search strategies, such as self-assessment and skills assessment, are given. (EJT)

Building on a prior investigation of users' formulations and needs in fiction, this study was conducted to determine dominant patterns in public library user-librarian search interactions. Based on analysis of 134 actual user-librarian conversations about fiction recorded under everyday library conditions in Danish public libraries in 1976, it was…

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…

The Florida R & D Utilization Project has two major goals: to provide schools with access to the best available R & D products and practices to resolve local needs, and to assist schools in developing a capacity for diagnosing and resolving instructional and other problems. This paper describes the 7-step conceptual model that governs the…

Provides an overview of the development and use of numeric databases, and of the evolution of user charging methods for all online information retrieval systems. The need to provide database users with advance estimates of charges is discussed, and a methodology for charge estimation is presented. (87 references) (CLB)

Describes a method for advance estimation of user charges for queries in relational data model-based numeric databases when charges are based on data retrieved. Use of this approach is demonstrated by sample queries to an imaginary marketing database. The principles and methods of this approach and its relevance are discussed. (MBR)

Some salient concepts derived from the information sciences and currently used in theories of human memory are critically reviewed. The application of automata theory is proposed as a new approach in this field. The approach is illustrated by applying it to verbal memory. (Author)

Examines traditional and interactive models that have emerged in information retrieval (IR), and proposes an interactive IR model based on different levels in the interactive processes. Analyzes strengths and weaknesses of the traditional model. Concludes with general remarks on the state of IR interaction research. (Author/AEF)

Revises David Ellis's information-seeking behavior model of social scientists which includes six generic features: starting, chaining, browsing, differentiating, monitoring, and extracting. Suggests four new features be added: accessing, networking, verifying, and information managing; and describes a new model that includes searching, accessing,…

Provides a model for librarians to expand their traditional teaching roles in order to reach users outside the library building. Describes the development of a series of modules designed to teach users how to do research on the Web based on experiences at Widener University, and considers future possibilities. (Author/LRW)

Discusses term weighting formulae and their use for selecting new terms to enhance a search statement and for weighting the terms for retrieval purposes once selected. The Swets model of information retrieval system performance is described, an approach to term selection is presented, and future research is suggested. (five references) (LRW)

Analyzes the search process, isolating the pertinent elements that make up a search and identifying the many decision points in the process. (Author/PF)

Offered as an alternative to the search strategy model for bibliographic instruction, the approach to library instruction in psychology which is described involves analysis of the natural structure of the research literature. An example using Festinger's theory of cognitive dissonance is presented. Twelve references are cited. (EJS)
