- Abstract
- Many retrievalexperiments are intended to discover ways of improving performance, taking the results obtained with some particular technique as a baseline. The fact that substantial alterations to a system often have little or no effect on particular collections is puzzling. This may be due to the initially poor seperation of relevant and non-relevant documents. The paper presents a procedure for characterizing this seperation for a collection, which can be used to show whether proposed modifications of the base system are likely to be useful.

- 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
- This paper presents a mathematical model of an information retrieval system thought to be general enough to serve as an abstract representation of most document and reference retrieval systems. The model is made up of four components that, in one form or another, appear in every functioning system. It is proved that the basic organization of documents that the system provides for a user on receipt of a request follows from the properties and interrelations of the four components. Each component is then discussed in turn and it is seen that much of the existing theory regarding information systems can be viewed as an elaboration of this model

- 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
