Describes the CCF (Common Communication Format) and the INFLIBNET (Information and Library Network) standard, two forms of metadata developed to represent the bibliographic resources available to libraries and to facilitate easy retrieval of resources. Proposes a crosswalk between core CCF and INFLIBNET bibliographic data fields and 15 Dublin Core…

Discusses hierarchical text classification for electronic information retrieval and the measures used to evaluate performance. Proposes new performance measures that consist of category similarity measures and distance-based measures that consider the contributions of misclassified documents, and explains a blocking measure that identifies…

Describes a test collection that was developed as a multi-purpose testbed for experiments on the Web in distributed information retrieval, hyperlink algorithms, and conventional ad hoc retrieval. Discusses inter-server connectivity, integrity of server holdings, inclusion of documents related to a wide spread of likely queries, and distribution of…

Discusses the use of text retrieval methods based on probabilistic models with Chinese language material, which are modeled on the Okapi information retrieval system. Topics include system architecture, test collections, weighting functions, and algorithms. (Author/LRW)

Presents a background on theory in knowledge organization, which has moved from an epistemic stance of pragmatism and rationalism (based on observation of the construction of retrieval tools), to empiricism (based on the results of empirical research). Discusses historicism, external validity, classification, user-interface design, and…

Presents a user modeling system for personalized interaction and tailored retrieval that tracks interactions over time, represents multiple information needs, allows for changes in information needs, acquires and updates the user model automatically, and accounts for contextual factors. Describes three models: general behavioral, personal…

Discusses access to digitized images in information retrieval and cognitive engagement with viewed images. Describes an investigation that looked at how users view images in relation to how they can be described, or categorized, and in what manner they match other images in the same collection. (Author/LRW)

Outlines four overlapping dimensions of context, including information environment level, information seeking level, IR (information retrieval) interaction level, and query level (linguistics), and discusses how they are related to various issues in IR research. Suggests further areas of research that are needed to fully understand the…

Discussion of electronic image processing focuses on the need for indexing to ensure adequate retrieval. Highlights include icons, i.e., reduced pictorial surrogates; file staging; indexing languages, including examples of thesauri; and pictorial languages, including a HyperCard system. (Contains eight references.) (LRW)

Describes a string-searching algorithm for multiple patterns in a text string; explains the construction of a pattern-matching machine; presents a theoretical analysis and empirical evidence that supports the sublinearity of the algorithm; and compares this algorithm with the Boyer-Moore algorithm for a single pattern. (Contains 10 references.)…

Introduces four articles on the development of information retrieval standards by people closely involved in the process. Standards organizations are described, addresses are given, and information sources are listed. (five references) (EA)

Compares two information retrieval systems, CLARIT and TOPIC, in terms of assigned versus derived and precoordinate versus postcoordinate indexing. Models of information retrieval systems are discussed, and a test of the systems using a demonstration database of full-text articles from the "Wall Street Journal" is described. (Contains 21…

Describes a conceptual framework for browsing based on the representation of knowledge states and documents. Topics addressed include browsing as searching without a topic; the inadequacy of bibliographic representation for scholarly work; browsing as a response to subject indeterminacy; and components of browsing activity. (Contains 34…

Report on exploratory research which investigated image attributes in a series of describing tasks. Results suggest that access to a wide range of attributes is needed to address all facets of interest and that certain classes of attributes may appear more frequently (literal objects, human form and associated attributes, color, and location).…

Discusses information retrieval in the Chinese language and describes three representation methods for texts: 1-gram or character, bigram, and short-word. Describes a study that investigated using more than one method simultaneously to improve retrieval effectiveness and considers word segmentation and costs. (Author/LRW)
