Abstract
In a sensor network, a sensor data processing apparatus generates a feature vector identifier table by classifying feature vector identifiers of a plurality of situation information determination reference data to be a reference of situation determination according to a sensor type index and a feature vector identifier set index of the plurality of situation information reference data. When the sensor data processing apparatus receives sensor data, the sensor data processing apparatus generates a feature vector identifier of the sensor data and extracts a sensor type index and a feature vector identifier set index of a feature vector identifier most similar to the feature vector identifier of sensor data with reference to a feature vector identifier table, and generates situation recognition information using the extracted sensor type index and feature vector identifier set index.
