Investigates the structural differences in the representation of balance and imbalance information by using a technique originated by Sternberg (1966). Subjects were 38 college students. (MP)

As part of the study of human information search strategy the concept of the search tactic, or move made to further a search, is introduced. Twenty-nine tactics are named, defined, and discussed, and implications of search tactics for research in search strategy are considered. (Author/MBR)

Discusses restrictions regarding use of bibliographic data bases, cites their rationale in terms of cooperation in input creation, economics and administrative control, and notes their effect on use. (Author/CWM)

Describes a component of a general biology course that emphasizes use of the science library. Initial instruction involves use of standard reference materials. Then four in-library exams are assigned, where a research question is answered using reference materials. Student reactions have been favorable. (CS)

Outlines results of a pilot study examining what constitutes a landmark in hypertext. Seven subjects began a search task from the same Indiana University School of Library and Information Science Homepage; searches had to be conducted without the use of search engines, and strictly following hypertext links. (Author/AEF)

Developments in the representation of music, in notated and acoustic forms, in computerized databases suggest a need for nontext searching. Examines aspects of music notation and sound and reviews literature concerned with basic considerations of musical document representation; systems for encoding music for storage, regeneration, and analysis;…

Describes the design and implementation of a system for computer generation of linked HTML (Hypertext Markup Language) documents to support information retrieval and hypertext applications on the World Wide Web by adding an interactive indexing technique that is compatible with Web browsers. (Author/LRW)

Introduces a generic, application-independent model of human-computer information-seeking dialog, the Conversational Roles (COR) Model, and reviews the theoretical background. COR is represented as a recursive state-transition-network that determines legitimate types and possible sequences of dialog acts, and categorizes dialog acts on the basis…

Proposes a summarization system for multiple documents that employs named entities and other signatures to cluster news from different sources, as well as punctuation marks, linking elements, and topic chains to identify the meaningful units (MUs). Using nouns and verbs to identify similar MUs, focusing and browsing models are applied to represent…

Presents a literature review that covers the following topics related to Latent Semantic Analysis (LSA): (1) LSA overview; (2) applications of LSA, including information retrieval (IR), information filtering, cross-language retrieval, and other IR-related LSA applications; (3) modeling human memory, including the relationship of LSA to other…

Presents a literature review that covers the following topics related to indexing, browsing, and searching of digital video: video coding and standards; conventional approaches to accessing digital video; automatically structuring and indexing digital video; searching, browsing, and summarization; measurement and evaluation of the effectiveness of…

This special issues comprises nine papers presenting a wide selection of approaches to handling subjectivity, vagueness, and imprecision in information retrieval (IR) and database management necessary for success in designing, developing and implementing effective tools for information access. (LRW)

Discusses imprecision in multimedia data on the Web and proposes a formal framework in which to formulate powerful queries and presentations of the answers. Introduces a fuzzy-based algebra which allows user preferences, in the form of weights, to alter query expression, and presents algorithms for the evaluation of similarity-based queries.…

Describes a study that investigated users' perceptions of ease of use versus user control in Web-based online information retrieval (IR) systems. Discusses desired features and functionalities as well as desired interface structures that support both ease of use and user control. (Author/LRW)

Discussion of image database systems focuses on semantic queries and shows how an image is abstracted into a hierarchy of entity names and features; how relations are established between entities visible in the image; and how a "fuzzy" matching technique is used to compare semantic queries to image abstractions.
