Abstract

The research of life pattern is a hot topic in the field of LBSN (Location Based Social Network). Periodic behavior is also a life pattern. In view of multiple periodic behaviors existed in time series, an algorithm which can mine all periods in time series is proposed in this paper. In view of periodic behaviors always occurred at the same time interval and the random access of matrix’s characteristic, the algorithm creates a suspected periodic matrix which can store all suspected periods. By judging the validity of a suspected period in the matrix, the true periods can be mined accurately. Updating the suspected periodic matrix dynamically can reduce executing time.
