Detailed examples illustrate one of the possible applications for using the computer punch card for information retrieval in qualitative historical research, suggesting a time-saving method of organization for research data. (SM)

The problems of using English for information retrival are delineated. The querying capability of a keyword dialog system is illustrated with actual computer output. Major advantages of this approach are: reduced ambiguity in requests, users may think in smaller functional units, and users may edit previous requests. (7 references) (Author/SJ)

A design method for information retrieval systems, based on a modelling technique, and derived from the general objectives and tasks set for the system is described. (12 references) (SJ)

A review is given of doubly-chained trees for information retrieval. It is shown that the chaining steps may be of different cost depending upon whether the step is vertical or horizontal. The problem of constructing an optimal retrieval tree is formulated mathematically and a solution procedure given. (5 references) (Author/KE)

The operational retrospective retrieval service offered by BIOSIS exploits a file created essentially without vocabulary control. A pragmatic program of file building criteria has been persued which has provided improved retrieval and an annual summary of the vocabulary of the literature. (11 references) (Author/KE)

A Mathematical model for use in studying how to minimize the cost of operating a mechanized retrieval system is developed. Through the use of cost analysis, the model provides a method for comparative evaluation between information retrieval systems. (15 references) (Author/SJ)

The adaptability of the theory of integrative levels to a generalised classification scheme is questioned in that its hypotheses have not been adequately developed and confirmed. It is suggested that not enough cognisance has been taken of twentieth century relativistic thinking in which space-time is treated as a continuum. (14 references)…

Discusses computer programs for aid in teaching, student diagnosis and learning developed by the National Cash Register Company. (MK)

The concern of this paper is to portray a rational response to the problems of providing computerized information services in the medium-to-large university. (6 references) (Author)

The New York Times" Information Bank is described in detail. Scheduled to be in operation in 1972, this project makes available abstracts of newspaper articles for on-line search and retrieval, combined with microform copies of the original articles. (Author)

Natural language systems are seen as falling into two classes - those which process and analyse the input and store it in an ordered fashion, and those which employ controls at the output stage. A variety of systems of both types is reviewed, and their respective features are discussed. (12 references) (Author/NH)

Interaction and interactive systems involve the computer and complexities when an abstracting and indexing service relates to its users. Kinds of interactions are: between government and industrial services; between discipline - and project - oriented services; on a national versus international level; and between the user and the computer.

In the field of United States history, the influence of abstracting and indexing services upon the use of serial literature, because of the highly inadequate retrospective and util recently, current access they afford to it, can only be regarded as a negative use. (Author)

The index entries generated by the Selective Listing in Combinations (SLIC) technique constitute a lattice which is a subset of the power set of the set of descriptors assigned to a document and this fact leads to an improved algorithm for generating SLIC entries. (Author/MF)
