ABSTRACT:
A method is provided for selecting a core collection of objects from an overall source collection. The objects have directed relations with each other, and a frequency measure of these directed relations is used as an approximation of the probability that one object has relevance to another. The method is particularly applicable to selecting a core collection of journals from an overall collection, wherein the object relation is journal citation. The selection method includes as procedural steps: (1) selecting a most frequently cited journal as a starter journal; (2) computing the frequencies of citation of other journals by the starter journal as measures of probability of relevance; (3) selecting a threshold relevance value, identifying the journals having relevance probabilities exceeding the threshold, then repeating the step for each identified journal until no new journals are identified; (4) determining dominance relations between every two journals identified; and (5) ordering the selected journals according to their dominance relations.
