Discusses the integration of knowledge management into business applications. Topics include the difference between knowledge and information; performance-centered design (PCD); applying knowledge to support business outcomes, including context, experience, and information quality; techniques for merging PCD and knowledge management, including…

Traditional themes of information science must be expanded to accommodate systematic understandings of ways to design effective documentary systems and anticipate their social consequences. The field of social informatics offers important concepts, theories, and methods that give this kind of inquiry a sound scientific basis. Social informatics…

Presents a method for extracting maximal frequent sequences in a set of documents. A maximal frequent sequence is a sequence of words that is frequent in the document collection and is not contained in any other longer frequent sequence. Frequent maximal sequences can be used as content descriptors for documents. (MES)

Reviews models of information behavior and introduces a model based on the goal-directed behavior of problem solving. A key part of the information seeking and searching process, 'uncertainty reduction,' is being explored in a project supported by the British Library Research and Innovation Center. Preliminary results from the pilot phase of the…

Examines cognitive maps on research topics generated by experts and non-experts. Both experts and non-experts modified the given vocabulary by either adding or dropping terms. The dominant configuration for the maps was top-down. Experts tended to use a problem-oriented approach to organize vocabulary while non-experts often applied a…

Provides an introduction to articles in this special "Perspectives" issue of "Journal of the American Society for Information Science and Technology." The articles, taken collectively, contain significant elements of a research agenda in image indexing and retrieval for the next decade. Articles focus on user, representation,…

Discussion of commercial document retrieval focuses on a two-part searching procedure based on identifiable partitions. Topics include system growth and the effects of information technology; content searching on large databases, including partitioning; the granularity of context; resolving queries; document retrieval and the World Wide Web; and…

The role played by Big6 Turbo Tools in helping students with Location and Access is highlighted. The functions of the Dictionary, Planner, TurboWrite, WebLinks and the Bulletin Board are explained.

Google Scholar, the beta Google service for searching scholarly information, crawls scholarly, web-based content--predominantly by targeting specific publishers with which Google has contractual arrangements. Open access material is crawled as well. These full-text materials, abstracts, and citations are being indexed, and citations from these…

In 3 experiments the authors examined changes in successive exemplar generation percentages within categories defined semantically (e.g., fruit-P, fruit-A, fruit-M) and by 1st letter (e.g., insect-C, sport-C, car-C), with a mixed control condition (e.g., fruit-P, insect-C, disease-M). Retrieval success declined across 12 successive items in both…

Results from two multiple regression models involving HighWire journal subscriptions in 2003 for 16 participating universities in the United States, United Kingdom, and Sweden indicate a highly predictive relationship between the number of article downloads and the number of users--meaning that the size of a user population can be estimated by…

Millennial students make up a large portion of undergraduate students attending colleges and universities, and they have a variety of online resources available to them to complete academically related information searches, primarily Web based and library-based online information retrieval systems. The content, ease of use, and required search…

This paper presents an information agent and latent semantic-based indexing architecture to retrieve documents on the Internet. The system optimizes the search for documents in the Internet by automatically retrieving relevant links. The information used for the search can be obtained, for instance, from Internet browser caches and from grades of…

This exploratory investigation of the process of defining the information needs of computer users and the impact of that process on information retrieval focuses on communication problems. Six sites were visited that used computers to process data or to provide information, including the California Department of Transportation, the California…

Batch mode processing is compared, using cost-effectiveness, with on-line processing for computer-aided searching of chemical abstracts. Consideration for time, need, coverage, and adaptability are found to be the criteria by which a searcher selects a method, and sometimes both methods are used. There is a tradeoff between batch mode's slower…
