Abstract

Reports results of a questionnaire survey, conducted by the EQUIP consortium, of 989 European and Scandinavian users of online and CD-ROM databases to establish a priority ranking of quality criteria. The project also included a test of the SERVQUAL methodology for identifying users' expectations of database services involving assessments of the quality criteria for both an 'ideal' database service and the CAB Abstracts Service. The 10 quality criteria identified were: coverage; accessibility; timeliness; consistency; accuracy; value; documentation; harmonization; output formats; and support

Abstract

In "Part 3. Successive Searching.'' where Spink is the primary author, after a review of the work on successive searching, a portion of the Texas generated data is reviewed for insights on how frequently successive searching occurred, the motivation for its occurrence, and any distinctive characteristics of the successive search pattern. Of 18 mediated searches, half requested a second search and a quarter a third search. All but one seeker reported a need to refine and enhance the previous results. Second searches while characterized as refinements included a significantly higher number of items retrieved and more search cycles. Third searches had the most cycles but less retrieved items than the second. Number of terms utilized did not change significantly and overlap was limited to about one in five terms between first and second searches. No overlap occurred between the second and third searches. Problem solving stage shifts did occur with 2 moving to a later stage after the first search, 5 remaining in the same stage and one reverting to a previous stage. Precision did not increase over successive searches, but partial relevant judgments decreased between the second and third search.

Abstract

In this issue we begin with the first of four parts of a five part series of papers by Spink, Wilson, Ford, Foster, and Ellis. Spink, et alia, in the first section of this report set forth the design of a project to test whether existing models of the information search process are appropriate for an environment of mediated successive searching which they believe characterizes much information seeking behavior. Their goal is to develop an integrated model of the process. Data were collected from 198 individuals, 87 in Texas and 111 in Sheffield in the U.K., with individuals with real information needs engaged in interaction with operational information retrieval systems by use of transaction logs, recordings of interactions with intermediaries, pre, and post search interviews, questionnaire responses, relevance judgments of retrieved text, and responses to a test of cognitive styles. Questionnaires were based upon the Kuhlthau model, the Saracevic model, the Ellis model, and incorporated a visual analog scale to avoid a consistency bias.

Abstract

This entry outlines the development of models of information behavior. The concept of a model is defined and the different types of model are identified. Models of information behavior are presented within a typology of descriptive model, decision-based models, and causal models. It is suggested that, in research terms, a movement from descriptive models to causal models is needed if theory development is to take place in the field.

Abstract

In "Part 2. Uncertainty and Its Correlates,'' where Wilson is the primary author, after a review of uncertainty as a concept in information seeking and decision research, it is hypothesized that if the Kuhlthau problem solving stage model is appropriate the searchers will recognize the stage in which they currently are operating. Secondly to test Wilson's contention that operationalized uncertainty would be useful in characterizing users, it is hypothesized that uncertainty will decrease as the searcher proceeds through problem stages and after the completion of the search. A review of pre and post search interviews reveals that uncertainty can be operationalized, and that academic researchers have no difficulty with a stage model of the information seeking process. Uncertainty is unrelated to sex, age, or discipline, but is related to problem stage and domain knowledge. Both concepts appear robust.

Abstract

Purpose - Apart from information retrieval there is virtually no other area of information science that has occasioned as much research effort and writing as "user studies". Within user studies the investigation of "information needs" has been the subject of much debate and no little confusion. The aim of this paper is to attempt to reduce this confusion by devoting attention to the definition of some concepts and by proposing the basis for a theory of the motivations for information-seeking behaviour. Design/methodology/approach - The paper describes the issues of user studies and information needs within the context of information science. Findings - The paper finds that the problem seems to lie, not so much with the lack of a single definition, as with a failure to use a definition appropriate to the level, and purpose of the investigation. Originality/value - The analysis may be used as a springboard to research based upon a wider, holistic view of the information user.

Abstract

In "Part 4. Cognitive Styles in Information Seeking,'' where Ford is the primary author, the results of the application of the Riding's Cognitive Styles Analysis and the Pask's holist/serialist portion of the Ford's Study Process Questionnaire to the 111 U.K. participants. were correlated using Spearman's coefficient with reports of focused thinking, degree of change in the intermediary's perception of the problem and personal knowledge, problem stage, degree of differentiating activity, change in problem perception, engagement in exploring activity, changes in questioning, valuing of serendipitous information, and other variables. The results would indicate that field independent individuals report clearer more focused thinking, see themselves in an earlier problem stage, and report higher levels of change in perception of the problem. Holists value serendipity and report engagement in Kuhlthau's exploring stage. They are seen by intermediaries as exhibiting fewer changes in questioning behavior. A fifth section will appear in a later issue.

Abstract

This paper explores collaborative information behavior in the context of highly politicized decision making. It draws upon a qualitative case study of project management of a contentious public sector infrastructure project. We noted the creation of spaces for the development and exchange of information by experts and conceptualize these as information spheres. We postulate that these were formed to bypass power-induced information behavior that excludes expert power, such as information avoidance. This approach contrasts with the expected project management and information norms, rules and behavior, however, provides a language that can be used to explain the phenomena of bounded information spaces which complement and may be used as a development of adjunct to small world's theory.

Abstract

This paper presents an outline of models of information seeking and other aspects of information behaviour, showing the relationship between communication and information behaviour in general with information seeking and information searching in information retrieval systems. It is suggested that these models address issues at various levels of information behaviour and that they can be related by envisaging a 'nesting' of models. It is also suggested that, within both information seeking research and information searching research, alternative models address similar issues in related ways and that the models are complementary rather than conflicting. Finally, an alternative, problem-solving model is presented, which, it is suggested, provides a basis for relating the models in appropriate research strategies.

Abstract

Business process re-engineering (or redesign) has achieved mixed results in business and industry but it offers an approach to thinking about the future of academic libraries in the digital age that is worth considering. This paper outlines the forces that are currently affecting academic libraries in the UK and proposes a strategy whereby the transformation from the handling of artefacts to the handling of electronic sources may be effected with maximum benefit to the information user.

Abstract

Apart from information retrieval there is virtually no other area of information science that has occasioned as much resarch effort and writing as 'user studies'. Within user studies the investigation of 'information needs' has been the subject of much debate and no little confusion. The aim of this paper is to attempt to reduce this confusion by devoting attention to the definition of some concepts and by proposing the basis for a theory of the motivations for information-seeking behaviour
