The Development of a Highly Interactive Searching Technique for MORPHS--Minicomputer Operated Retrieval (Partially Heuristic) System.
Peer reviewed Peer reviewed
Bell, C. L. M.; Jones, K. P. – Information Processing and Management, 1980
Explains, with supporting figures and flowcharts of programing logic, two search strategies introduced to the MORPHS System since 1976: one that employs the normal Boolean operators in strings without bracketing or in the form of marked steps, and one that treats a string of keywords as a compound word.

Fuzzy Information Retrieval Using Genetic Algorithms and Relevance Feedback.
Petry, Frederick E.; And Others – Proceedings of the ASIS Annual Meeting, 1993
Describes an approach that combines concepts from information retrieval, fuzzy set theory, and genetic programing to improve weighted Boolean query formulation via relevance feedback. Highlights include background on information retrieval systems; genetic algorithms; subproblem formulation; and preliminary results based on a testbed. (Contains 12…

A Graph Structured Text Field Index Based on Word Fragments.
Peer reviewed Peer reviewed
Kropp, 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)

ON CLUSTERING TECHNIQUES OF CITATION GRAPHS.
CHIEN, R.T.; PREPARATA, F.P. – 1967
ONE OF THE PROBLEMS ENCOUNTERED IN CLUSTERING TECHNIQUES AS APPLIED TO DOCUMENT RETRIEVAL SYSTEMS USING BIBLIOGRAPHIC COUPLING DEVICES IS THAT THE COMPUTATIONAL EFFORT REQUIRED GROWS ROUGHLY AS THE SQUARE OF THE COLLECTION SIZE. IN THIS STUDY GRAPH THEORY IS APPLIED TO THIS PROBLEM BY FIRST MAPPING THE CITATION GRAPH OF THE DOCUMENT COLLECTION…

Continuity in an Environment of Perceptual Discontinuity: The Significance of the Algorithm in Exploitative Power.
Vigil, Peter J. – 1989
Online information retrieval is pervasive and its development in libraries is accelerating. Within the near future, most college and research libraries will provide direct access to their patrons to vast information resources via CD-ROMs, locally mounted databases, and gateways. The computer terminal and the "frame" of information it…

Relational Data System Study. Final Report, 12 December 1969-12 June 1970.
Minker, Jack; Sable, Jerome – 1970
A relational data system (RDS) is one that has the capability not only to retrieve specific facts but also the ability to deduce facts that are implicit rather than explicit in the data base. The study investigated the application of RDS technology to intelligence data processing. RDS technology and the nature of intelligence data processing are…

Toward Direct Access Intelligence Systems.
Von Foerster, Heinz – 1970
Two accomplishments have increased the feasibility of taking preparatory steps for the construction of machine intelligence systems which can acquire knowledge about facts or descriptions of facts through man-machine dialogue in the user's natural language. One is a better understanding of the relationship between perception, language, and…
