Training with complex event processing engine to identify semantic meaning of virtual world object state changes

A system for identifying state changes in objects in virtual worlds, the system comprising:

• a computer processor;
• an event processing unit configured to observe base events, to determine by the computer processor that a group of one or more of the observed base events is correlated to a candidate higher-level event, wherein determining that the group of one or more of the observed base events is correlated to the candidate higher-level event is based at least in part on statistical analysis of the observed base events;
• and
• a training unit configured to receive user input confirming that the group of base events is correlated to the candidate higher-level event, and if the received user input specifies that the group of base events is correlated to the candidate higher-level event, to store the candidate higher-level event as an identified higher-level event.

A computer program product for training a system to identify state changes in objects in virtual worlds, the computer program product comprising:

• a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code configured to:
• observe a group of one or more base events;
• determine by a computer processor that the group of one or more of the observed base events is correlated to a candidate higher-level event, the candidate higher-level event including at least some of the observed base events, wherein determining that the group of one or more of the observed base events is correlated to the candidate higher-level event is based at least in part on statistical analysis of the observed base events;
• receive user input confirming that the group of base events is correlated to the candidate higher-level event;
• and
• if the received user input specifies that the group of base events is correlated to the candidate higher-level event, store the candidate higher-level event as the identified higher-level event.
