SEMANTIC RELATION EXTRACTION METHOD USING PATTERN PAIRS SHARING A TERM FOR ONTOLOGY CONSTRUCTION

摘要

PURPOSE: A semantic relation extraction method using pairs of pattern sharing a term for ontology construction is provided to select the pairs of terms more proper to represent a semantic relation by extracting the semantic relation for the terms placed in different sentences. CONSTITUTION: The sentences of high-capacity document are refined, and the analysis for the refined sentences is performed. The pairs of terms which belong to each sentence and the patterns placed between the pairs of the terms are extracted by using a dictionary. The pairs of patterns sharing the terms placed in different sentences and the rest terms are extracted, and the semantic relation for the pairs of the terms placed in the different sentences is extracted by using the pairs of patterns sharing the rest terms.
