1. A system for estimating the temporal validity of location reports through pattern analysis, said system comprising:

  • a. a mode selector identifying a data analysis mode, said data analysis mode being an online mode when immediate analysis of location data is to be performed, and said data analysis mode being a batch mode when data analysis is triggered either manually or periodically;

    b. a receiver receiving location records from one or more tracked entities and storing said location records in one or more databases;

    c. an analysis trigger triggering data analysis tasks based upon said identified data analysis mode, said analysis trigger responsible for periodically forwarding to a classifier received location data in said batch mode, and said analysis trigger forwarding said received location data onto said classifier in said online mode;

    d. said classifier clustering and partitioning location data, and said classifier, in an online mode, receiving a single location data from a tracked entity and repartitioning already partitioned data in said databases corresponding to said tracked entity and based upon said received location data, and said classifier, in a batch mode, clustering and repartitioning location data in said databases corresponding to a tracked entity upon a request from said analysis trigger, and e. an expiration time analyzer performing pattern analysis and estimating expiration times associated with each of said repartitioned data computed by said classifier, said expiration times providing a measure of the degradation of location reports over a period of time.
