This study evaluated online searching performed on the National Library of Medicine system to identify implications for training and continuing education. Searchers were selected with formal and informal training, from three different types of organization, and with differing levels of experience. It was found that most searchers have clearly…

Modeled on public databases such as Lockheed and SDC, the information system described in this report was utilized in the creation of in-house databases in the Mobay Chemical Corporation's special library in Pittsburgh. Using IBM's Storage and Information Retrieval System (STAIRS), Mobay created two databases: one to hold product information, the…

The Florida R & D Utilization Project has two major goals: to provide schools with access to the best available R & D products and practices to resolve local needs, and to assist schools in developing a capacity for diagnosing and resolving instructional and other problems. This paper describes the 7-step conceptual model that governs the…

Explores the fundamentals of browsing as a basis for the creation of an intelligent computer system to assist with the online retrieval of information, and describes a prototype system. The discussion covers various browsing retrieval strategies used and user reactions to the prototype. (Seven references) (Author/CLB)

Describes the inability of traditional subject index terms to represent relational information among concepts, and the development of frame based knowledge representation methods that provide relational semantic representations of documents and user queries. The discussion covers research in user interfaces and automatic document classifications,…

This paper studies the influence of question-related variables (closed/open and predictable/unpredictable) on a Web user's choice of search strategy in the initial stage of a search. Search strategies considered include direct address, subject directory, and search engine. Objectives were to determine the adaptiveness of Web users in choosing an…

This paper discusses personal resource discovery on the World Wide Web from the point of view of a reference librarian. Two key questions for finding information on the Internet are identified: (1) What are you actually looking for? and (2) Who is likely to have the information? Examples of this approach are provided, and some problems with using…

This paper reports on a transaction log analysis of 51,473 queries from 18,113 users of Excite, a major World Wide Web search engine. Approximately 2,500 of these queries were from the use of relevance feedback. Given the high level of research activity and historical success of relevance feedback in assisting users in locating relevant…

Searching for useful information on the World Wide Web has become increasingly difficult. While Internet search engines have been helping people to search on the Web, low recall rate and outdated indexes have become more and more problematic as the Web grows. In addition, search tools usually present to the user only a list of search results,…

FRED (a Front End for Databases) was conceived to alleviate data access difficulties posed by the heterogeneous nature of online databases. A hardware/software layer interposed between users and databases, it consists of three subsystems: user-interface, database-interface, and knowledge base. Architectural alternatives for this database machine…

Discusses the goals of library catalogs, how and to what extent these goals are achieved, and differences which exist among online, card, book, and microform catalogs. Access and display of information are noted, highlighting form of entries (main entries, corporate authorship, subject description) and search strategies. Seven references are…

Examines traditional and interactive models that have emerged in information retrieval (IR), and proposes an interactive IR model based on different levels in the interactive processes. Analyzes strengths and weaknesses of the traditional model. Concludes with general remarks on the state of IR interaction research. (Author/AEF)

Examines the transition from traditional single database retrieval to the emerging networked resources retrieval, and presents research and experimental solutions developed at the University of California, Berkeley. Highlights include recall and relevance, network navigation, vocabulary, and extending retrieval records. (LRW)

Discussion of the selection of search terms during an online search involving users and intermediaries focuses on a study that investigated at what stage of the search process search terms from different sources were selected, how terms were connected with retrieval of relevant answers, and the sequences in which terms were selected. (Contains 16…

Focuses on the retrieval of numeric data from information sources that present special challenges. Describes a new method to deal with the challenge of accessing this special type of data indexed by unfamiliar metadata vocabularies. Extends the entry vocabulary module (EVM) approach to deal with numeric database searching. (AEF)
