對於發展和使用ontology來說支援ontology evolution和方便儲存取得ontology是很重要的,本文在ontology management system (OMS)上強調ontology evolution的重要性,利用basic change operations建置出evolution table,以及透過parse evolution table來產生evolution log的方式,來支援OMS 內ontology evolution問題。 For developing and using ontology, it is important to supporting ontology evolution and facile accessing ontology. This thesis emphasizes the importance of ontology evolution in the ontology management system. It utilizes basic change operations to construct evolution table and parses evolution table to generate evolution log. Using this method can support ontology evolution in OMS.
