Abstract: A method for processing data and a system thereof are provided to check an ICS(Interactive Communication Sequence) for a plurality of users from communication records by using a variable time window as well as an ICSP(Interactive Communication Sequence Pattern) that is an interactive communication sequence frequently generated from among the checked interactive communication sequence. A searcher(121) searches the inverse pairs in the communication record. An ICS extractor(130) includes an ICS extractor without extension of a time window(131) and an ICS extractor with extension of a time window(132), and extracts an interactive communication sequence having a length other than 1. The ICS extractor without extension of a time window checks a new interactive communication sequence in which an interactive communication sequence included in the set S establishes another interactive communication sequence included in the set S as a sub interactive communication sequence, and adds the newly generated ICS to the set S. The ICS extractor with extension of a time window combines the inverse pair that is included in the candidate set S generated by the set generator and the ICS that is included in the set S that is finally determined by the ICS extractor without extension of a time window to generate an ICS having a length other than 1, and adds the generated interactive communication sequence to the set S.
