Patent ID: 8055663

Claim:
A system for measuring behavior characteristics stored in a non-transitory machine-readable storage medium, comprising: a domain hierarchy comprising a plurality of concepts and associations therebetween; a database storing network content for a plurality of users, where the network content comprises a plurality of key terms, and a plurality of interaction behaviors therebetween, wherein each of the interaction behaviors involves at least two users, and has a corresponding type weighting, in which different interaction behaviors have different type weightings; a term-concept association matrix recording association degrees for respective key terms toward respective concepts; and a processing module, for at least one specific user, calculating a concern score for respective concepts according to use frequency of respective key terms corresponding to the specific user, use frequency of respective key terms corresponding to all users, and the term-concept association matrix, calculating a relation matrix for at least one specific concept according to the at least two users corresponding to respective interaction behaviors, the type weighting corresponding to respective interaction behaviors, and the association degree for at least one key term used in the interaction behaviors toward the specific concept, calculating an interaction score for the specific user regarding the specific concept according to the relation matrix using an algorithm, and calculating a characteristic score for the specific user regarding the specific concept according to the concern score and the interaction score, wherein the processing module calculates the relation matrix according to the formula, wherein “x” in the formula means a cross product: R ij = ∑ S × AD , UA = i ⁢ ⁢ UB = j wherein R ij represents interaction relation strength for the ith user toward the jth user under the specific concept, respective interaction behavior is represented by (UA, UB, S, AD), where UA and UB represents two users corresponding to one interaction behavior, S represents the type weighting corresponding to the interaction behavior, and AD represents the association degree for the key term used in the interaction behavior toward the specific concept.
