Patent ID: 8117135

Claim:
A user-concerned information provision system comprising: a plurality of user terminals to provide contents transmitted from an external server to a user; a user-concerned information inference server to infer an association relationship between the contents based on information of maximum playing time and actual playing time of the contents provided to the user terminals; and a content provision server to provide a content requested by an arbitrary one of the user terminals and other contents associated with the requested content according to the inferred association relationship to the arbitrary one of the user terminals when receiving a request of the content from the arbitrary one of the user terminals, wherein the user-concerned information inference server applies the maximum playing time and the actual playing time of the contents to a fuzzy association rule inquiry algorithm to infer the association relationship between the contents, and wherein the user-concerned information inference server applies the information of the maximum playing time and the actual playing time of the contents to a membership function to find a transaction, calculates a support degree according to a transaction for each content using the found transaction, extracts a candidate content pair having a support degree equal to or greater than a predetermined reference value to calculate an association degree between the candidate contents, and, when the association degree is equal to or greater than a predetermined reference association degree, determines the candidate content pair to be interoperable contents.
