1. Computer-implemented method (300) for recognizing an event pattern (ABC) for objects (14, 24, 34, 44) that belong to an event domain (150), the method (300) comprising:

  • activating (310) a pattern query (110) that corresponds to the event pattern (ABC) and that has a least one state (S4) with a distinctive transition probability (P(S4/S2), P(S2/S3)) to a final query state (S3), the probability being derived from object observations in the event domain (150);

    continuously receiving (320) event representations (*A14, *A24, *A44, *D44, . . . ), that are related to the objects (14, 24, 34,

         44);

    allocating (330) the event representations (*A14, *A24, *A44, *D44, . . . ) to a first processing resource (101) to initiate (331) instances (1.14, 1.24, 1.34, 1.44) of the query (110);

    monitoring (340) the instances and, upon receiving event representations that cause the instances to reach the state (S4) with the distinctive transition probability (P(S4/S2), P(S2/S3)), shifting (342) the instances to a second processing resource (102).
