Describes a study that collected statistics on the occurrence of terms used in searching an online catalog and investigated the correlation of the selection of terms with their occurrence in indexing. The discussion of the results includes implications for indexing theories. (19 references) (CLB)

Highlights semantic links and shows how the semantic content of hypertext links can be used for information retrieval. Discussion includes indexing and retrieval algorithms that exploit link content and node content; retrieval strategies exploiting semantic links, including conventional retrieval and constrained spreading activation techniques;…

Describes the SAPHIRE (Semantic and Probabilistic Heuristic Information Retrieval Environment) that was developed to identify optimal approaches to indexing, retrieval, and evaluation of information retrieval systems in the biomedical domain. Six evaluation studies that have been done with SAPHIRE are summarized and future challenges are…

Describes a system based on a probabilistic inference network retrieval model that was used to study the retrieval effectiveness benefits of combining types of document and query information that are found in typical commercial databases and information services. Multiple document representations, multiple index representations, and multiple query…

Presents an improved inverted region quadtree variation called Dynamic Inverted Quadtree that is able to support and index a pictorial database. Pattern-searching algorithms are described, and the space needs of Fully Inverted and Dynamic Inverted Quadtrees are analytically compared based on a model of image randomness expressed as a branching…

Describes the Kodak Picture Exchange that includes a database of over 200,000 photographic images collected from 28 stock photography companies in the United States that allows the user to search for images by topic. Highlights include installing the software, alternative search strategies, costs, manipulating images, and rules governing the use…

Describes libraries' use of the Internet to provide information on their local collections and explains how to provide searchable indexes through the use of WAIS (Wide Area Information Server) software. Highlights include Waisindex; file formats; Waissearch; and accessing WAIS indexes via a gopher, WAIS, or WWW (World Wide Web) server. (LRW)

Provides a brief history of the American Society of Indexers (ASI) and assesses its position among other organizations, such as ASIS, involved with the organization of information. Topics discussed include the annual award for best monograph index; the ASI newsletter; and publicity to convey the importance of quality indexing. (LRW)

This test of the Strategy of Unlimited Aliasing, an indexing method that places terms from several indexers for the same information object in one index, utilized bibliographic records from the ERIC, LISA (Library and Information Science Abstracts), and ISA (Information Science Abstracts) databases. The test did not support the indexing method.…

Discussion of human-computer interfaces focuses on the use of graphical and direct manipulation approaches to improve the user interface. Topics discussed include information seeking; computerized search capabilities, including full-text string searches, index searches, and hypertext; Boolean expressions; dynamic or direct manipulation queries;…

Describes Archie, an electronic indexing service for locating information on the INTERNET. The resource discovery problem addressed by the service is summarized, and instructions for accessing Archie are provided. The current scope of the Archie service and plans for the future are discussed. Other information discovery and delivery tools…

Presents a logical analysis of the characteristics of indexing and their effects on retrieval. The foundational questions of performance evaluation and the basic quantitative performance measures for binary noninteractive retrieval systems are established. The effects of indexing devices, indexing exhaustivity, specificity, correctness, and…

Reviews the literature relating to the development and application of modern imaging technology between 1987 and 1993. Highlights include image representation, including image data, compression, and image formats; and image access, including indexing and modeling, user interface design, and distributed access. (143 references) (LRW)

Describes a study that examined the rates of use of descriptors in the ERIC (Educational Resources Information Center) system during 1966-86 to determine whether certain levels of terms were used more than others and whether patterns of use were similar among hierarchies in the ERIC Thesaurus. (10 references) (LRW)

Describes the evolution of audiocassette tapes and considers benefits of using tapes in distance teaching. Problems associated with tapes are discussed; the use of tapes by print-handicapped students is described; and possible solutions to drawbacks are suggested, including organization of contents, cassette indexing, self-pacing, and…
