SYSTEM AND METHOD FOR RANKING SEARCH RESULTS WITHIN CITATION INTENSIVE DOCUMENT COLLECTIONS

摘要

A computerized method is provided for calculating a normalized activity score value to rank an identified document. The method comprises identifying a stored document; determining a number of times the identified document was cited in a subject matter community of the identified document; determining a probability distribution that individual documents within the subject matter community are cited a variable number of times by other individual documents in the subject matter community; calculating a probability function by performing a regression on the probability distribution; calculating the activity score value according to an activity score function formulated as an inverse of the probability function; weighting the activity score value by an age of the identified document; and storing in computer memory a ranking of the identified document based on the activity score value.
