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.

Common data structures associated with procedurally-oriented software, such as Fortran COMMON blocks, are translated into object-oriented (OO) classes. Procedurally-oriented software modules are reduced in complexity by extracting an appropriate number of sub-modules from the original source code so that the original module and each extracted module is below a predetermined complexity level, if possible. The original module and extracted modules are assigned to an object-oriented class based upon a measure of each modules' association to the respective class' data members, where the assigned modules are then translated into object-oriented methods. This approach greatly reduces overall system development time and costs by automatically generating maintainable object-oriented code based upon translated procedurally-oriented source code. Man-hours are further saved by automatically documenting the newly generated object-oriented classes and by automatically generating test suite files for use in verifying and troubleshooting the automatically generated object-oriented classes.
