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. (Author/LRW)

Defines a method of using the constructs defined by the HyTime standard to structure scholarly writing and to affect its presentation through the use of dynamic multimedia presentations. Explores the potential power of descriptive hyperlinks as tools of scholarly discourse and analysis, and the system needed to aid historians in information…

Describes early Hebrew citation indexes, both embedded and book-length, and discusses terminological variation, format, precision of locators, the order of index entries and assumption of user knowledge, knowledge of the compilers, and recommendations for further research. (59 references) (LRW)

Discusses automated information retrieval, focusing on statistical patterns expected of a pair of terms that are semantically related to each other, guided by text generation conceptualization. Examines how the tendency of a content bearing term to clump, as quantified by previously developed measures of term clumping, is influenced by the…

Discusses automatic document classification and document retrieval systems and presents a strategy for building a morphological machine dictionary of English that infers meaning of derivations by considering morphological affixes and their semantic classification. Proposes a method for selecting compound field association terms from a large pool…

Discusses users' search behavior and decision making in data mining and information retrieval. Describes iterative information seeking as a Markov process during which users advance through states of nodes; and explains how the information system records the decision as weights, allowing the incorporation of users' decisions into the Markov…

Discusses search engines and describes a prototype system that provides dynamic ranking of search engine results for geospatial queries based on the URL of the host site. Evaluates this approach using user queries and random Web pages, making a contribution to Web retrieval by providing an alternative ranking order for search engine results.…
