- 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 inverted file structure is often used to organize data in the information retrieval system. When the hierarchy relation on the set descriptors and weights of descriptors in document description would be taken into account, the conventional concept of the inverted file may be extended. Properties and operations on inverted files, which are used in systems based on thesaurus with weights, are studied in this paper

- "Fassen wir das Ergebnis zusammen und formulieren es zugleich als Aufgabenkatalog für die Computer-Industrie, so müssen wir feststellen, daß auf der Hard ware-Seite sowohl OCR-Leser mit einem für die Literatureingabe hinreichenden Zeichenvorrat wie Random-Access-Speicher mit Kapazitäten über 108 Zeichen fehlen. Das Problem der OCR-Leser läßt sich wahrscheinlich am leichtesten lösen. Es reicht wohl aus, die bisherige Entwicklung weiter auszubauen. Was die Speicher angeht, so glaube ich, daß der bisherige Weg der Plattenspeicher bei den hier diskutierten Größenordnungen nicht gangbar ist. Es wird die Entwicklung von Festkörperspeichern abzuwarten sein, die die Molekülstrukturen ausnutzen. Erste hoffnungsvolle Ansätze liegen bei der Entwicklung von Dünnschichtspeichern vor. Sie sind jedoch noch nicht funktionsreif. Eine energische Weiterentwicklung benötigt auch die Soft ware. Hier müssen selbstprogrammierende Systeme angestrebt werden, die nach allgemeinen Grundmodellen unnormierte Anfragen in vorgegebene Parameter bringen. Dies ist wegen der Kompliziertheit der logischen Abläufe in semantischen Prozessen sicherlich nur in einem Dialogverkehr zwischen Frager und Computer möglich. An solchen Systemen sind nicht nur die Bibliothekare und Dokumentalisten interessiert, sondern alle Kreise, die Information verarbeiten, einschließlich der Management Information. Es ist daher zu hoffen, daß finanziell potentere Stellen als die Bibliotheken diese Entwicklung vorantreiben."

- 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
- 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
- This paper defines the relationship between linguistics and information science in terms of a common interest in natural language. The notion of automated processing of natural language - i.e., machine simulation of the language processing activities of a human - provides novel possibilities for interaction between linguistics, who have a theoretical interest in such activities, and information scientists, who have more practical goals, e.g. simulating the language processing activities of an indexer with a machine. The concept of a natural language information system is introduces as a framenwork for reviewing automated language processing efforts by computational linguists and information scientists. In terms of this framework, the former have concentrated on automating the operations of the component for content analysis and representation, while the latter have emphasized the data management component. The complementary nature of these developments allows the postulation of an integrated approach to automated language processing. This approach, which is outlined in the final sections of the paper, incorporates current notions in linguistic theory and information science, as well as design features of recent computational linguistic models
