    Abstract
    Research shows that 65-80% of subject search terms fail to match the appropriate subject heading and one third to one half of subject searches result in no references being retrieved. Examines the subject search terms geberated by 82 school and college students in Princeton, NJ, evaluated the match between the named terms and the expected subject headings, proposes an explanation for match failures in relation to 3 invariant properties common to all search terms: concreteness, complexity, and syndeticity. Suggests that match failure is a consequence of developmental naming patterns and that these patterns can be overcome through the use of metacognitive naming skills

    Abstract
    This paper investigates two relatively new measures of retrieval effectiveness in relation to the problem of incomplete relevance data. The measures, Bpref and RankEff, which do not take into account documents that have not been relevance judged, are compared theoretically and experimentally. The experimental comparisons involve a third measure, the well-known mean uninterpolated average precision. The results indicate that RankEff is the most stable of the three measures when the amount of relevance data is reduced, with respect to system ranking and absolute values. In addition, RankEff has the lowest error-rate.

    Abstract
    This contribution reports the results of continuing research in human-information system interactions. Following training and experience with an electronic information retrieval system novice and experienced subject groups responded to questions ranking their value assessments of 7 attributes of information sources in relation to 15 factors describing the search process. In general, novice users were more heavily influenced by the process factors (negative influences) than by the positive attributes of information qualities. Experienced users, while still concerned with process factors, were more strongly influenced by the qualitative information attributes. The specific advantages and contributions of this research are several: higher dimensionality of measured factors and attributes (15 x 7); higher granularity of analysis using a 7 value metric in a closed-end Likert scale; development of bi-directional, firced-choice influence vectors; and a larger sample size (N=186) than previously reported in the literature

    Abstract
    The problem of measurement in information retrieval research is traced to its source in the first retrieval tests. The problem is seen as presenting a chronic dilemma for the field. This dilemma has taken 3 forms as the discipline has evloved: (1) the dilemma of measurement in the archetypal approach: stated relevance versus user relevance; (2) the dilemma of measurement in the probabilistic approach: realism versus formalism; and (3) the dilemma of measurement in the Information Retrieval-Expert System (IR-ES) approach: linear measures of relevance versus logarithmic measures of knowledge. It is argued that the dilemma of measurement has remained intractable even given the different assumptions of the different approaches for 3 connecte reasons - the nature of the subject matter of the field; the nature of relevance jidgement; and the nature of cognition and knowledge. Finally, it is concluded that the original vision of information retrieval research as a discipline founded on quantification proved restricting for its theoretical and methodological development and that increasing recognition of this is reflected in growing interest in qualitative methods in information retrieval research in relation to cognitive, behavioral, and affective aspects of the information retrieval interaction
