A polydimensional scheme for information retrieval

American Documentation, 1962, vol. 13, issue 1, 90-92

Abstract: A method is discussed for integrating a man and machine into a library retrieval system for overcoming certain deficiencies in today's manual systems and meeting certain additional criteria. One of the basic criteria is that the machine must extend the user's effective intellect by performing intelligence functions now performed by him and by enabling him to perform intelligence functions not now possible. A hypothetical (although not impossible) man‐machine complex is advocated by assuming the Aristotelian concept that within the ameboid structure of knowledge are classes and that these classes can be logically defined to categorize all knowledge. Following this assumption, logical conceptional relationships can be structured using retrieval terms, with each term showing a readily apparent relationship to the whole field of knowledge. These poly‐dimensional relationships can be said to exist, not just in a vertical dimension, but also each term can have its own horizontal level of abstraction, a relative universe created by its relationships to multitudinous terms throughout the structure. Each term, its universe, and the concepts embodied in it constitute expanding concentric circles of categorical knowledge, with each circle showing a diminishing degree of conceptual synonymity with the central term. A unique machine application is discussed to allow the user to perceive the relationships between terms. The system enables the user to place himself at a known spot in the entire field of knowledge and with the aid of machine coordination move in any direction from concept to concept until the desired retrieval point is reached.
