Abstract: Presents a recently composite view of several user studies in information retrieval. Contains personal conclusions and speculations based on these studies, rather than formal statistical results, which so often are not comparable from 1 experiment to another. Suggests a taxonomy of user characteristics for such studies, in order to make results comparable. Discusses methods and effects of user training, then manner of expression of a query or information need, conduct of a search, use of the system command language or its equivalent, analysis by the user of retrieved information, and user satisfaction with outcome. Concludes with suggestions for system design and experimental methodology

Abstract: Proposes a new method of evaluating information retrieval systems by concentrating on individual tools in the context of their use, rather than systems as a whole. A tool is a command, its menu or graphic interface equivalent, or a move or stratagem. A user would render an assessment of the relative success of a small part of a search, and every tool used in that part would be credited with a contribution to the result, whether positive or negative. The cumulative scores would provide an assessment of the overall utility of the tool

Abstract

Attemps to define the term: information; and challenges the assumptions often made about familiar concepts used in evaluating information services. Comments on the fact that do not always report the definitions of the variables they measure, or the circumstances of the measurement, with enough precision to enable others to use them. Illustrates the points with particular reference to the ambiguity evident in the use of the term 'relevance' when applied to information and notes the difficulty in sharing data among information science researchers in the absence of agreed upon standards

Abstract

This article reports on an exploratory study of the measurement of commonality in the use of variables or measures by authors and groups of authors who have reported on studies of information retrieval system users. There is some similarity to co-citation analysis in that, when 2 individual papers, or 2 authors of sveral works, use the same variables, this indicates a similarity in approach to the subject. Such usage may be a stroger indication of similarity than co-citation be cause it represents what the authors did, rather than what they say
