摘要：The event representation together with the sensor data grounding method, both presented here, relates sensor reading values to natural language (NL) phrase descriptions. The representation consists of (1) event descriptors each of which has its own physical quantity expression that reflects an interpretation of an event and (2) a composition rules. As an application of the event representation, the event search system is briefly described.
