CITATION INDEX AND MEASURES OF ASSOCIATION IN MECHANIZED DOCUMENT RETRIEVAL. RAPPORT NUMMER 2. (REPORT NUMBER 2).
CITATION INDEXES, IN COMBINATION WITH REGULAR INDEXES, ARE CREATING NEW METHODS OF INFORMATION RETRIEVAL, WHICH USE SOME MEASURE OF CONNECTION OR ASSOCIATION BETWEEN A GIVEN BASE OF ARTICLES AND OTHER DOCUMENTS IN A COLLECTION. GENERAL REQUIREMENTS OF SUCH A MEASURE ARE--(1) IT SHOULD BE INDIRECTLY PROPORTIONAL TO THE NUMBER OF LINKS IN A CHAIN OF CITATIONS BETWEEN THE TWO ARTICLES BEING MEASURED, AND (2) IT SHOULD BE DIRECTLY PROPORTIONAL TO THE NUMBER OF CHAINS CONNECTING THE TWO ARTICLES. THE FIELD OF THERMODYNAMICS OFFERS A SIMPLE PHYSICAL ANALOGY TO THIS MEASURE. MATHEMATICAL PROCEDURES BASED UPON THERMODYNAMICS ARE USED TO DERIVE AN ALGORITHM FOR FINDING THE DEGREE OF ASSOCIATION.
