- Abstract
- Jedem der drei Stadien der Bevölkerungskurve entspricht ein bestimmter sozialer Charakter, der die Verhaltenssicherheit der Menschen bestimmt. In der Periode des hohen Bevölkerungsumsatzes wurde das soziale Dasein durch traditionelle Normen stabilisiert, die von Generation zu Generation weitergegeben werden konnten. Riesman nennt die Menschen der mittelalterlichen Gesellschaft deshalb traditionsgeleitet. Im Stadium der Expansion wurden die traditionellen Normen abgebaut. Jede neue Generation sah sich Fragen gegenüber, die mit dem überlieferten sozialen Vorstellungskanon der vorangegangenen Generation nicht mehr bewältigt werden konnten. Die Verhaltenssicherheit mußte auf andere Weise gewährleistet werden. Es geschah schließlich dadurch, daß sich die Individuen in der Geseilschaft der Bevölkerungswelle "frühzeitig ein Schema, von verinnerlichten Lebenszielen aneigneten". Sie erhielten keine Anweisungen mehr für die jeweilige konkrete Situation, weil sie unvorhersehbar geworden war, sondern nur noch bestimmte prinzipielle Leitvorstellungen. Riesman gebraucht dafür das Bild vom Kreiselkompaß im Innern des Individuums und nennt diese Form des sozialen Charakters innengeleitet.

- Abstract
- A study of the number of irrelevant documents retrieved in a co-ordinate indexing system that does not employ eitherr roles or links. These tests were based on one hundred actual inquiries received in the library and therefore an evaluation of recall efficiency is not included. Over half the enquiries produced no noise, but the mean average percentage niose figure was approximately 33 per cent based on a total average retireval figure of eighteen documents per search. Details of the size of the indexed collection, methods of indexing, and an analysis of the reasons for the retrieval of irrelevant documents are discussed, thereby providing information officers who are thinking of installing such a system with some evidence on which to base a decision as to whether or not to utilize these devices

- Abstract
- Two widerly used criteria for evaluating the effectiveness of information retrieval systems are, respectively, the recall and the precision. Since the determiniation of these measures is dependent on a distinction between documents which are relevant to a given query and documents which are not relevant to that query, it has sometimes been claimed that an accurate, generally valid evaluation cannot be based on recall and precision measure. A study was made to determine the effect of variations in relevance assesments do not produce significant variations in average recall and precision. It thus appears that properly computed recall and precision data may represent effectiveness indicators which are gemerally valid for many distinct user classes.

- Abstract
- It is argued that the evaluation of information-retrieval systems should ultimately be based on the principle of rationality, the maximization of expected utility. In full generality this would involve an estimation of both the cost and value of a system, but the emphasis in this paper is on the problem of value, in terms of which the effiency of the system could be defined. One implication of the discussion is that it is not legitimate to superimpose the 2x2 contingency tables that refer to select/discarded and relevant/irrelevant, correspondending to each request,but it might be all right to superimpose them after applying a monotonic function to the entries. In particular, it is questionable whether a useful statistic is the ratio of the total number of relevant selected documents to the total number of relevant ones, over a sample of requests.
