Ontology - based Semantic Value Conversion

In the face of massive Web data, an important task is to integrate relevant data of interest from users in Deep Web into a unified and structured form. In order to facilitate the identification and processing of computers, each data item needs to be annotated. Ontology is the key to semantic tagging. In order to facilitate the sharing and exchange of information, the semantic value of ontology instances must be consistent and compatible. In this paper, a semantic value conversion method based on ontology is proposed. This method is divided into two parts, one is to define the conversion function as the entry point of the semantic value conversion. The second is to use OWL as the ontology language description, and establish an OWL ontology relational database to store the relationship between ontology instances and various semantic values. The semantic value conversion method improves the integrity and consistency of the ontology instance semantic information.
