- Abstract
- After establishing the terminology, shows how the choice of the name of the subject of a document and the rendering of the name in the heading of the specific subject entry can be got by facet analysis based on postulates and principles. After showing that subject headings constitute an artificial language, points out that using facet analysis for subject heading does not amount to using class number. Marks out the area for an objective statistical survey of sought heading for subject entry. Calls on Council for Library Resources Incorporated to provide for this project

- Abstract
- Reports on a novel technique for literature indexing and searching in a mechanized library system. The notion of relevance is taken as the key concept in the theory of information retrieval and a comparative concept of relevance is explicated in terms of the theory of probability. The resulting technique called 'Probabilistic indexing' allows a computing machine, given a request for information, to make a statistical inference and derive a number (called the 'relevance number') for each document, which is a measure of the probability that the document will satisfy the given request. The result of a search is an ordered list of those documents which satisfy the request ranked according to their probable relevance. The paper goes on to show that whereas in a conventional library system the cross-referencing ('see' and 'see also') is based soley on the 'semantic closeness' between index terms, statistical measures of closeness between index terms can be defined and computed. Thus, given an arbitrary request consisting of one (or many) index term(s), a machine can eleborate on it to increase the probability of selecting relevant documents that would not otherwise have been selected. Finally, the paper suggest an interpretation of the whole library problem as one where the request is considered as a clue on the basis of which the library system makes a concatenated statistical inference in order to provide as an output an ordered list of those documents which most probably satisfy the information needs of the user

- Abstract
- Wilson argues that the subject of a writing is indetermined, by which he means either it is impossible to say which of two descriptions is 'the' description of the subject of a writing or it is impossible to say if a writing has two subjects rather than one.

- Abstract
- Index language (the system of symbols for representing subject content after analysis) is considered as a separate component and a variable in an information retrieval system. It is suggested that for purposes of testing, comparing and evaluating index language, the techniques of structural linguistics may provide a descriptive methodology by which all such languages (hierarchical and faceted classification, analytico-synthetic indexing, traditional subject indexing, indexes and classifications based on automatic text analysis, etc.) could be described in term of a linguistic model, and compared on a common basis

- Abstract
- The need for criteria by which to judge the adequacy of an abstract is felt most strongly when evaluating machine-produced abstracts. In order to develop a set of criteria, a survey was conducted of the instructions prepared by various scientific publications as a guide to their abstracters in the preparation of copy. One-hundred-and-thirty sets of instructions were analyzed and compared as to their function, content, and form. It was concluded that, while differences in subject matter do not necessarily require different kinds of abstracts, there are significant variations between the informative and the indicative abstract. A set of criteria for the writing of an acceptable abstract of science literature was derived. The adequacy of these criteria is still to be validated, and the athors' plans for fututre research in this area are specified

- Abstract
- A summary of the findings of various evaluations of role indicators is given. In general, the results have been negative in that little real evidence for the value of the devices has been presented. The need for roles in various subject fields and in very large systems, is discussed. They can only by justified on purely ecomic grounds - if the added cost involved in their use is offset by substantial reduction in the amount of output screening that must be done by the end user

- Abstract
- The principles here stated apply only to the choice and form of headings and entry words - i.e. to the principal elements determining the order of entries - in catalogues of printed books in which entries under authors' names and, where these are inappropriate or insufficient, under the titles of works are combined in one alphabetical sequence. They are framed with special reference to catalogues enumerating the contents of large general libraries: but their application to the catalogues of other libraries and to other alphabetical lists of books is also recommended, with such modifications as may be required by the purposes of these catalogues and lists.

- Abstract
- The information retrieval process, treated strictly as a matching procedure, has the defects that the whole file must be probed for each query, and that it overlooks the facts that the relevance of the information from one document depends upon what is already known about the subject, and in turn affects the relevance of other documents subsequently examined. A mathematical model of a search technique in which the defects of the direct method are taken into account is demonstrated by an experiment in which a given paper is treated as an enquiry and the references cited in the paper are treated as relevant answers. The results in two tests show much better results than those achieved by the direct method. No spurious material was retrieved by either method
