    Abstract
    The use of weights to denote a query representation and/or the indexing of a document is analysed as a generalization of a Boolean retrieval system. Criteria are given for the functions used to evaluate the relevance of the records to a specific query, including self-consistency. Various mechnaisms suggested in the literature for evaluating the relevance of records with regard to a given query are tested and found to be less than satisfactory. A new approach is suggested to avoid some of the perils of a weighted Boolean retrieval system

    Abstract
    The aim of a document retrieval system is to issue documents which contain the information needed by a given user of an information system. The process of retrieving documents in response to a given query is carried out by means of the search patterns of these documents and the query. It is thus clear that the quality of this process, i.e. the pertinence of the information system response to the information need of a given user depends on the degree of accurary in which document and query contents are represented by their search patterns. It seems obvious that the weighting of descriptors entering document search patterns improves the quality of the the document retrieval process. A mathematical apparatus which takes into consideration, in a natural manner, the fact that the grades of importance of the descriptors in document search patterns are of the contimuum type, that is an apparatus adequate to the description of a retrieval system of documents indexed by weighted descriptors is - among known mathematical methods - the theory of fuzzy sets

    Abstract
    The retireval of documents by content is based on identifiers that are seldom unique to a document. Therefore, a query is usually answered by a number of documents that may, however, differ in relevance to the query. Ranking algorithms attempt to assess these relevances by calculating a relevance measure, and order the documents on the basis of the measure. Surveys the algorithms found in the literature for the weighting of index terms and the calculation of relevance measures, classifies them according to various criteria, and compares a number of them empirically. Methods are discussed for further classification of the algorithms on the basis of similarity of behaviour. These are demonstrated for a data base of 1.003 legal documents. It is shown that one may considerably improve the quality of ranking by combining algorithms from different classes
