Peer reviewedDavis, Charles H. – Special Libraries, 1972
A straightforward procedure for performing weighted-term searches can be programmed quickly and easily, and the same general algorithm can be used for either on-line or batch mode searching. The method can be used to do whole text searches as well as conventional searches for index terms or other descriptors. (5 references) (Author/NH)

Peer reviewedCadolino, C.; Guazzo, M. – Information Processing and Management, 1982
Considers problem of optimal scheduling of Boolean expression (each Boolean variable represents binary outcome of program module) on single-processor system. Optimization discussed consists of finding operand arrangement that minimizes average execution costs representing consumption of resources (elapsed time, main memory, number of…

The Maryland Refutation Proof Procedure System (MRPPS) is an interactive experimental system intended for studying deductive search methods. Although the work is oriented towards question-answering, MRPPS provides a general problem solving capability. There are three major components within MRPPS. These are: (1) an inference system, (2) a search…

Peer reviewedKropp, D.; Walch, G. – Information Processing and Management, 1981
Describes an indexing technique based on overlapping word fragments as reference strings that are linked in a directed graph structure which makes possible exact match-, partial match-, and masked-partial match-retrieval and indicates search strategies for each case. Eight figures, two tables, and nine references are provided. (RBF)

Peer reviewedde Heer, T. – Information Processing and Management, 1982
Addresses problem of developing machine-based information system capable of indicating one document, out of a set of documents written in natural language, which shows maximal degree of homeosemy (relationship in meaning between two texts language-fragments ) toward natural language query. Linguistic aspects, information traces, trigrams,…

Lipetz, Ben-Ami – 1970
Utilization of the card catalog in the main library (Sterling Memorial Library) of Yale University was studied over a period of more than a year. Traffic flow in the catalog was observed, and was used as the basis for scheduling interviews with a representative sample of catalog users at the moment of catalog use. More than 2000 interviews were…
