Abstract
A method for performing a semantic analysis process on a computer system including a storage unit and an interface includes the steps of: receiving a syntactic tree generated from a natural language sentence text; determining whether an analysis object, which is one of nodes of the syntactic tree, is a verb phrase class which has a verb as a head or a non-verb phrase class which has mainly a noun as the head on the basis of subdivided type information of a phrase of the node with reference to first data stored in the storage unit; analyzing a relation between a verb in the analysis object and a deep case of the verb when the analysis object is the verb phrase class; analyzing a modificative relation in the analysis object when the analysis object is the non-verb phrase class; generating a semantic structure of the natural language sentence text wherein the semantic structure comprises semantic frames corresponding to nodes of the syntactic tree, at least two semantic frames of the semantic frames being linked by a head relation or a deep case relation or a modificative relation, and storing the semantic structure in the storage unit or displaying the semantic structure on a display which is connectable to the computer system via the interface.
