SITUATION ESTIMATION SYSTEM, SITUATION ESTIMATION METHOD, AND SITUATION ESTIMATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a situation estimation system for permitting various types of sensors as a plurality of sensors to be mounted on a user terminal.;SOLUTION: In the situation estimation system, the plurality of sensors including the same type of sensors as those to be mounted on the user terminal 200 are installed in advance in predetermined situations where a user is assumed to exist. The situation estimation system is provided with: a sensor data collecting means 101 for collecting a sensor observation value for each situation from the plurality of sensors; a sensor data management means 102 for generating output probability of the sensor observation value as predetermined probability distribution for each situation from the collected sensor observation value, and for storing the generated probability distribution into a probability distribution storage part 105; and a feature vector generation means 103 for estimating conditioned probability that the user exists in each situation when receiving the sensor observation value of the user terminal 200 based on the sensor observation value of the user terminal 200 and the probability distribution stored in the probability distribution storage part 105.;COPYRIGHT: (C)2010,JPO&INPIT
