Surveys the field and literature of geographic information systems (GIS) and spatial data representation as it relates to GIS. Highlights include GIS terms, data types, and operations; vector representations and raster, or grid, representations; spatial indexing; elevation data representations; large spatial databases; and problem areas and future…

Describes a database-filtering approach that combines citation, indexing, and productivity analyses as an effective tool for identifying journals that support multidisciplinary research and development, based on a study of biotechnology research and development. Cocitation analysis, including cocitation maps; subject heading profile analysis; and…

The Latent Semantic Indexing and MatchPlus systems examine similar contexts in which words appear and create representational models that capture the similarity of meaning of terms and then use the representation for retrieval. Text Retrieval Conference experiments using these systems demonstrate the computational feasibility of using…

Presents a study by Texas A&M University to find steps to improve access to engineering society technical papers. Steps include: consolidating indexes, creating finding guides, changing shelving procedures, and utilizing gopher-client servers. A table displays indexing results via an online system and appendixes offer an example of a gopher…

Argues that indexing and classification schemes rely on an understanding of "subject" and discusses several different conceptions of subject as epistemological positions. It is further argued that a theory of subject must be based in a theory of knowledge, and a theory based on a realistic/materialistic epistemology is proposed. (39…

Describes the development of an in-house bibliographic database by the U.S. Army Corp of Engineers Cold Regions Research and Engineering Laboratory on arctic wetlands research. Topics discussed include planning; identifying relevant search terms and commercial online databases; downloading citations; criteria for software selection; management…

Describes the following steps in CD-ROM production: (1) information base creation; (2) data preparation, conversion, and verification; and (3) indexing and premastering. Cost factors for each step and overall trends in CD-ROM production costs are also discussed. (three references) (EA)

Argues that information retrieval based on semantic representation is not helpful for those searchers who do not have well-defined ideas of the target document type. Presents an alternative, complementary method for indexing and document retrieval based on attributes of argumentation, a characteristic of articles advancing a claim. (52 references)…

Discussion of telecommuting possibilities focuses on a program at Information Access Company that allows indexers and abstractors to work at home. Employer and employee expectations are discussed, equipment provisions are described, employee benefits are examined, and implications for the library environment are suggested. (LRW)

The current state of information retrieval (IR) evaluation is reviewed with criticisms directed at the available test collections and the research and evaluation methodologies used, including precision and recall rates for online searches and laboratory tests not including real users. Automatic text retrieval systems are also discussed. (32…

Reports on a study that analyzed 3,746 papers obtained from retrospective searches of the Medline database according to language, length of abstract, depth of indexing, and inclusion of author's address. The focus is on scientific production in Slavonic countries and the information value of Slavonic papers in Medline. (10 references) (MES)

Identifies current trends in the automation of indexing, of information retrieval, and of interaction between the system and the users. Topics discussed include location, navigation, and indexing; digital libraries; matching documents to queries; weight of concepts; query structure, including fuzzy sets; algorithms; stemming; clustering; users'…

Describes a study of professional searchers that investigated their decisions about using search terms. The use of descriptors from a controlled vocabulary versus the use of textwords for free-text searching is examined, searching styles and differences in subject areas are discussed, and the quality of thesauri and indexing is considered. (six…

Proposes that methods intended to assist in information retrieval be grouped together and that the group be called "informed retrieval," a process which uses feedback from an information system to improve retrieval results. It is suggested that an integrated framework be developed that includes authority control and informed retrieval as…

This issue presents 11 articles that address issues relating to the production of CD-ROMs. Highlights include current uses of CD-ROM; standards; steps involved in producing CD-ROMs, including data capture, conversion, and tagging, product design, and indexing; authoring; selecting indexing and retrieval software; costs; multimedia CD-ROMs; and…
