1. A method comprising:

  • receiving, by a computer processor of a computing device from RFID tags embedded in sensors, first event data associated with a first plurality of events detected by said sensors, said computer processor controlling a cloud hosted mediation system comprising an inference engine software application, a truth maintenance system database, and non monotonic logic;

    associating, by said computer processor, first portions of said first event data with associated RFID tags of said RFID tags;

    deriving, by said computer processor executing said inference engine software application, first assumption data associated with each portion of said first portions of said first event data;

    retrieving, by said computer processor from said truth maintenance system database, previous assumption data derived from and associated with previous portions of previous event data retrieved from said RFID tags embedded in said sensors, said previous assumption data derived at a time differing from a time of said deriving, said previous event data associated with previous events occurring at a different time from said first plurality of events;

    executing, by said computer processor, said non monotonic logic with respect to said first assumption data and said previous assumption data;

    generating, by said computer processor executing said non monotonic logic and said inference engine software application, first updated assumption data associated with said first assumption data and said previous assumption data; and

    storing, by said computer processor in said truth maintenance system database, said first assumption data and said first updated assumption data.
