Claim 13:
14. An information processing method comprising:
acquiring object data including data about a plurality of objects constituting a power plant and relationships between the plurality of objects;
acquiring ontology data defining a plurality of association relationships between a plurality of objects and a plurality of properties, each association relationship between an object and a property indicating that the property is associated with the object;
detecting, based on the object data and the ontology data, a first object and a first property that are mentioned in a first electronic document;
estimating that the first object and the first property are in an association relationship;
determining whether the estimated association relationship between the first object and the first property is defined in the ontology data;
in response to determining that the estimated association relationship between the first object and the first property is not defined in the ontology data:
selecting a plurality of object candidates that are in an association relationship with the first property based on the ontology data;
for each of the plurality of object candidates, calculating a logical distance between the each of the plurality of object candidates and the first object based on the object data, and determining a relationship score of the each of the plurality of object candidates based on the logical distance;
selecting, instead of the first object, a second object that is in the association relationship with the first property from the plurality of object candidates based on the relationship score, the second object being within a predetermined distance from the first object; and
generating relationship information indicating that the first electronic document is related to the second object,

wherein it is determined whether the first object and the first property have a relationship of a reference designation, and
the second object is selected to have an inclusion relationship with the first object that is in the association relationship with the first property.
