Patent ID: 8589404

Claim:
A system for identifying the relevance of a data record to a subject of interest comprising: at least one non-transitory computer readable medium storing machine executable instructions comprising: an indexer configured to identify occurrences of each of a plurality of n-grams within the data record; a distribution generator configured to associate at least one of the plurality of n-grams with a semantic parameter, where a semantic parameter is a value derived at least one of associated meanings, inter-symbol structure, and associated source properties of the data record, and define a multinomial distribution from the respective numbers of occurrence of a subset of the plurality of n-grams and the assigned semantic parameter; a semantic model configured to represent a family of probability distributions as points on an information manifold, the information manifold having an intrinsic geometry defined by the family of probability distributions such that a distance between two points on the information manifold represents a similarity between the probability distributions represented by the two points and the semantic model storing the multinomial distribution as a point on the information manifold; a classifier configured to determine the relevance of the data record according to the position of the point on the information manifold; and a processor operatively connected to one or more of the at least one non-transitory computer readable media and configured to execute at least a subset of the machine executable instructions.
