ABSTRACT:
To construct an ontology for a target data by re-using an existing ontology, from an aspect of the structure of the class hierarchy according to an object-oriented method and an aspect of the levels of relevance with other properties, the properties that correspond to the data items in the data serving as an ontology construction target and the extraction classes of the properties are determined as property extraction destination candidates for the ontology to be constructed. As a result, it is possible to re-use even a fine difference in the meanings among the properties in the classes. Consequently, it is possible to provide a support for constructing an effective ontology, while reducing the load on the user.
