Abstract

Traces the history and development of cognitive research techniques in information science and surveys current research that relies on the cognitive aspect. Examines information systems that make use of the insights of cognitive research, including experimental and proposed systems. Examples include systems that are designed to make appropriate demands on user cognitive processing. Points out that cognitive research in information science has focused primarily on users of information systems and to a lesser extent on information intermediaries. Design initiatives deriving from this research have been directed toward developing information technology that can adapt to the knowledge abilities, and styles of individual users and that make efficient use of the knowledge base and cognitive process of groups of users

Abstract

Reports on a study which collected a sample of 846 scientific research papers published in 1992 and tests 3 hypotheses on the relationship between research collaboration and interdisciplinarity. Results showed significant differences in degrees of interdisciplinarity among different levels of collaboration and among different disciplines. Collaboration contributed significantly to the degree of interdisciplinarity in some disciplines and not in others. Uses a survey that asked authors about their form of collaboration, channels of communication and use of information. The survey provides some qualitative explanation for the bibliometrics findings. Discusses the perspective of scientist-scientist interaction, scientist-information interaction and information-information interaction

Abstract

1 characteristic that may affect the way users interest with information systems is the way they organise their knowledge of the topic to be searched. An experiment was conducted to determine the extent and nature of this effect. Subjects who were given different advance organisers read texts and responded to questions about the topics in the texts. These questions were presented in an information retrieval context, on simulated pre-search forms. It was found that different organising structures affected responses to questions in 1 topic of the 3 that were investigated. This demonstrates a complex interaction between the topic of the search, the organising structure employed by users, and questions asked by intermediaries. Because the way users organise their knowledge has an impact on their interaction with information systems, these organising structures may be candidates for inclusion in cognitive models of users

Abstract

This research investigated the ways in which different levels of knowledge about a topic can affect searching for information on that topic in a library online catalog. It was found that people with high levels of knowledge use more search expressions, including more general and nonproductive expressions, than low-knowledge users. It was also found that high-knowledge users employed more search expressions that had not been contained in their statements of information need than low-knowledge users. These differences in vocabulary use and search expression formulation may be of interest to designers of online catalogs as they attempt to increase the responsiveness of catalog systems to the needs of individual users

Abstract

Tests the logical reasoning ability of end users of a CD-ROM index and assesses associations between different levels of this ability and aspects of retrieval performance. Users' selection of vocabulary and their selection of citations for further examination are both influenced by this ability. The designs of information systems should address the effects of logical reasoning on search behaviour. People with lower levels of logical reasoning ability may experience difficulty using systems in which user selectivity plays an important role. Other systems, such as those with ranked output, may decrease the need for users to make selections and would be easier to use for people with lower levels of logical reasoning ability

Abstract

Explores the use of interactive documents as interfaces to historical data starting with the basis of the well known representation of a timeline. When incorporated into the context of electronic documents, the timeline provides the basis for implementing an interface into an event space, relying particularly on hypertextual-style links. Generalizing timelines also permits the flexible representation of many different kinds of relationships beyond the temporal. Describes examples of such representations taken from prototype implementations
