Abstract: A method and system for sensor signal data analysis are disclosed. In one aspect, a method includes acquiring sensor signal data from a plurality of sensors. Signal processing is performed on the sensor signal data to extract one or more features of the sensor signal data. The features are signal extracts that are distinguishable among and reproducible along the sensor signal data. With at least one of the features, a plurality of information attributes is associated, and information evaluation is performed on the plurality of information attributes.
