知識本體論廣泛地運用在知識表達，發展了各類的知識本體架構，卻對於知識本體論的呈現無法一致，導致知識整合上無法有效達成。統一知識本體塑模語言是一個結合各類知識本體架構下所使用的觀念和元件，所發展出的具統一規格之知識本體架構表達工具，以廣為運用的XML標示語言為基礎。如此，不但能將各類的知識本體架構，重新建置為統一規格的知識本體架構，甚至使用統一知識本體塑模語言所建構的知識本體，可以直接建置成XML文件，紀錄各個知識本體架構圖中相關資訊，並可藉XML文件中的標籤資料，建立關聯資料表，儲存其資料，輕易達到知識整合的最大效益。
Ontology has been widely used in knowledge construction and various types of ontology architectures are developed based on different knowledge representation. However, there is lack of tools which can introduce different ontology architectures in a unified way. Knowledge integration among ontology becomes an impossible mission or it cannot be done in an effective method. A unified ontology modeling language (UOML) is a tool based on XML, using concepts, components, and notations from many fields and ontology architectures, to demonstrate any ontology in a consistent specification. The use of the unified ontology modeling language can construct any ontology directly into a XML file. Each element in the ontology chart information may be translated to labeled information in the XML file which is then applied to build the corresponding database tables. The knowledge integration among different ontology can be easily done due to the representation of these ontology architectures are using the same tool.
