Automatic Ontology Generation from Natural Language Sentences Using Predicate Ontology
Youngkun Min, Bog-Ju Lee · Journal of Korea Multimedia Society · 2010
Ontologies, the important implementation tools for semantic web, are widely used in various areas such as search, reasoning, and knowledge representation. Developing well-defined ontologies, however, requires a lot of resources in terms of time and materials. There have been efforts to construct ontologies automatically to overcome these problems. In this paper, ontologies are automatically constructed from the natural languages sentences directly. To do this, the analysis of morphemes and a sentence structure is performed at first. then, the program finds predicates inside the sentence and the predicates are transformed to the corresponding ontology predicates. For matching the corresponding ontology from a in the sentence, we develop the predicate ontology. An experimental comparison between human ontology engineer and the program shows that the proposed system outperforms the human engineer in an accuracy.
