    Abstract
    I had the distinct pleasure of working with Pauline Atherton (Cochrane) during the 1960s, a period that can be considered the heyday of automated information system design and evaluation in the United States. I first met Pauline at the 1962 American Documentation Institute annual meeting in North Hollywood, Florida. My company, Westat Research Analysts, had recently been awarded a contract by the U.S. Patent Office to provide statistical support for the design of experiments with automated information retrieval systems. I was asked to attend the meeting to learn more about information retrieval systems and to begin informing others of U.S. Patent Office activities in this area. At one session, Pauline and I questioned a speaker about the research that he presented. Pauline's questions concerned the logic of their approach and mine, the statistical aspects. After the session, she came over to talk to me and we began a professional and personal friendship that continues to this day. During the 1960s, Pauline was involved in several important information-retrieval projects including a series of studies for the American Institute of Physics, a dissertation examining the relevance of retrieved documents, and development and evaluation of an online information-retrieval system. I had the opportunity to work with Pauline and her colleagues an four of those projects and will briefly describe her work in the 1960s.

    Abstract
    We report quantitative and qualitative results of an empirical evaluation to determine whether automated assistance improves searching performance and when searchers desire system intervention in the search process. Forty participants interacted with two fully functional information retrieval systems in a counterbalanced, within-participant study. The systems were identical in all respects except that one offered automated assistance and the other did not. The study used a client-side automated assistance application, an approximately 500,000-document Text REtrieval Conference content collection, and six topics. Results indicate that automated assistance can improve searching performance. However, the improvement is less dramatic than one might expect, with an approximately 20% performance increase, as measured by the number of userselected relevant documents. Concerning patterns of interaction, we identified 1,879 occurrences of searchersystem interactions and classified them into 9 major categories and 27 subcategories or states. Results indicate that there are predictable patterns of times when searchers desire and implement searching assistance. The most common three-state pattern is Execute Query-View Results: With Scrolling-View Assistance. Searchers appear receptive to automated assistance; there is a 71% implementation rate. There does not seem to be a correlation between the use of assistance and previous searching performance. We discuss the implications for the design of information retrieval systems and future research directions.

    Abstract
    Proceedings of the 5th TREC-confrerence held in Gaithersburgh, Maryland, Nov 20-22, 1996. Aim of the conference was discussion on retrieval techniques for large test collections. Different research groups used different techniques, such as automated thesauri, term weighting, natural language techniques, relevance feedback and advanced pattern matching, for information retrieval from the same large database. This procedure makes it possible to compare the results. The proceedings include papers, tables of the system results, and brief system descriptions including timing and storage information

    Abstract
    The evaluation of information retrieval systems is an important yet difficult operation. This paper describes an exploratory evaluation study that takes an interpretive approach to evaluation. The longitudinal study examines evaluation through the information-seeking behaviour of 22 case studies of 'real' users. The eclectic approach to data collection produced behavioral data that is compared with relevance judgements and satisfaction ratings. The study demonstrates considerable variations among the cases, among different evaluation measures within the same case, and among the same measures at different stages within a single case. It is argued that those involved in evaluation should be aware of the difficulties, and base any evaluation on a good understanding of the cases in question
