AUTOMATIC CONSTRUCTION METHOD AND AUTOMATIC CONSTRUCTION SYSTEM OF RELATIONS BETWEEN ONTOLOGY CLASSES OF TECHNICAL TERMS USING GENERAL DOMAIN CORPUS CLUSTERING

摘要

PURPOSE: An automatic construction method and an automatic construction system of relations between ontology classes of technical terms using general domain corpus clustering are provided to overcome limitation of a technical term corpus with few corpora and automatically extract the relations between concepts. CONSTITUTION: A syntax analyzing device(11) extracts a specific technical term and a verb pair related to the specific technical term from a technical term domain to construct relations of a technical term ontology. A corpus extractor(13) extracts a general corpus consisting of syntaxes in which a verb is included based on the extracted word from a generic domain. A clustering device(15) clusters verbs related to the technical term through the syntax relation of the syntaxes in the extracted general corpus. An automatic class relation setup device(17) sets relations between classes configuring the technical term ontology.
