A factor analysis of affective data gathered from searchers of an online library catalog, and a card catalog allowed researchers to isolate factors leading to success or failure in information retrieval. Factor patterns serve to identify how searches are evaluated by users. Further research is suggested as are features to facilitate successful…

A study of logical reasoning ability of endusers searching a CD-ROM index and its correlation to searching performance was conducted at the University of Illinois at Urbana-Champaign. Findings showed a correlation between cognitive skills and citation selection and indicated that computer system design can be improved using a cognitive engineering…

Demonstrates a means for estimating the number of retrieved items using well-established selective dissemination of information (SDI) profiles in the SCI, INSPEC, ISMEC, CAS, and PASCAL databases. A correlation between individual database size and number of retrieved documents in technical fields is also examined. (17 references) (LAE)

Describes the differences between English and Chinese information retrieval and the problems with Chinese character entry and encoding. It is argued that regular expression searching facilitates Chinese character entry and retrieval. Mathematical models are developed for controlling noisy characters retrieved by regular expressions containing…

Examines the literature on the myth of "hard science-soft science" as a means of defining scientific specialties and classifying science literature, and discusses some shortcomings of scholarship in library and information science. Use of Toulmin's categorization of sciences to organize the literature and provide access for scientists is…

Describes a study that compared the effectiveness of screen designs for system interfaces by tallying keyboarding errors during online searches. The methodology is described as an unobtrusive means for obtaining objective and empirically based data for interface comparisons. A questionnaire used to determine users' reactions to screen designs is…

Reviews the use of artificial intelligence research techniques to create tools that can assist with ongoing library functions and with information skills both within and outside of the library setting. Major areas discussed include cataloging, indexing, database searching, reference services, knowledge acquisition and representation, user…

Discusses the concept of gatekeepers in the area of information and culture and presents a model for the information-seeking behavior of ethnolinguistic gatekeepers. Highlights include information needs and use models; information inequity in information and retrieval programs; affective and cognitive domains; and research implications for…

Reviews the literature on qualitative methods in information retrieval research. Qualitative research is shown to be noncontrolling, holistic and case oriented, about processes, open and flexible, diverse in methods, humanistic, inductive, and scientific. Relevance to library and information science and sources of information on qualitative…

Reviews the research and commentary on individuals' questions and specific reference queries that characterize two general approaches in librarianship and other disciplines: question itself as phenomenon of questioner's behavior, linguistic performance, or cognitive state; interaction between question and answer focusing on appropriateness of…

Study describes actual and ideal linkage roles of four educators trained to link clients with online bibliographic retrieval service, effect of roles on clients' satisfaction with service, conceptualization of role in literature as compared with implementation in field, and implications of findings for educational knowledge dissemination. Twelve…

A study investigated the relationship between the completeness of end users' mental models of an online system and their ability to use the system effectively. Although all of the study subjects were relatively successful, those with more complete mental models tended to have better search results than subjects with incomplete or poor mental…

Describes British Library's work on Systems Dynamics, a set of techniques for building simulation models based on analysis of information feedback loops. Highlights include macro-simulation modelling activities of social science disciplines, systems analyses and models of information retrieval processes and library services, policy models, and…

This review of the transition from library card catalogs to online public access catalogs (OPAC) (1981-1982) discusses methods employed by online catalog use studies (self-administered questionnaires, OPAC transaction logs, focused-group interviews, feature analysis, online search and retrieval experiments) and new directions for OPAC research…
