  • Patent number: 11144595
    Abstract: First and second data catalogs each indicate sensing data attributes. The first and second data catalogs each include a first word indicating an observation object of a sensor that generated sensing data and a second word indicating an observation characteristic of the sensor. A score calculation unit includes a first weight determination part, a second weight determination part, and a score calculation part. The first weight determination part determines a first weight value relating to the observation object, based on the relationship between the first words included in the first and second data catalogs. The second weight determination part determines a second weight value relating to the observation characteristic, based on the relationship between the second words included in the first and second data catalogs. The score calculation part calculates a score relating to the coincidence of the first and second data catalogs, using the first and second weight values.
