Web-tables are ubiquitous in Web pages. Since tables themselves are organized structurally and semantically, they are good resources from which we can easily extract ontology. But, most Web-tables are designed for intuitive perception of humans, thus, it has a certain limit to interpret table content using only structural information of the table. So this paper focuses on the method for interpretation of table content based on semantic characteristics of the table. In order to obtain many property elements used for ontology inference, in this paper, the authors discuss how to extract ontology properties from Web-tables. The extracted properties include the following elements: Is-a relationship, class-instance relationship, triple, property domain, property range, symmetric property, transitive property, functional property, and inverse functional property, property for defining super-sub relationship. Through experiment, the authors show that their method can effectively extract property elements from Web-tables.
