- Abstract
- Attempts to discover patterns of similarity between a client's natural language statement of an information need and the natural language summaries of that need by human intermediaries. The intermediaries (20) were enrolled in an introductory reference and online information class. A qualitative analysis compares the opposing natural language texts using both frequency of occuring words and a word association measure taken from the Anomalous States of Knowledge (ASK) work. The analysis seems to indicate that there is a strong similarity among the summaries of the human intermediaries when compared by word frequency and word association measures based on proximity and co-occurrence

- Abstract
- This study sought to investigate the effects of cognitive style (field dependent and field independent) and on-line database search experience (novice and experienced) on the WWW search performance of undergraduate college students (n=48). It also attempted to find user factors that could be used to predict search efficiency. search performance, the dependent variable was defined in 2 ways: (1) time required for retrieving a relevant information item, and (2) the number of nodes traversed for retrieving a relevant information item. the search tasks required were carried out on a University Web site, and included a factual task and a topical search task of interest to the participant. Results indicated that while cognitive style (FD/FI) significantly influenced the search performance of novice searchers, the influence was greatly reduced in those searchers who had on-line database search experience. Based on the findings, suggestions for possible changes to the design of the current Web interface and to user training programs are provided

- Abstract
- Considers which metaphors and analogies communicate the structure and functions of the Internet and the WWW. Examines a set of journal article titles containing metaphorical references. These metaphors are content analyzed and compared against recommended criteria for evaluating the usefulness of metaphors in computer driven environments

- Abstract
- Examines some of the theories that have evolved to explain the mental processes required for the use of information systems. Categorizes research in this area into system oriented and user oriented studies and reviews this research. Describes a sample of methodologies used for examining users and their information seeking behaviour. Concludes with a discussion of the implications of these theories and methods for librarians and information specialists
