Description Logic extension based on extenics theory

Journal of Computer Applications
Traditional Description Logic (DL) does not fit to handle the problems with incomplete information, tracit knowledge or even contradiction premise. Therefore it is not sufficient to be the logical foundation of the Semantic Web. For this reason, the matter-element and divergence rules of Extenics were introduced to extend the traditional DL. Firstly, the semantic explanation of matterelement was given. Then the matter-element and divergence rules were used to extend the Tableau algorithm to be new Tableau-E algorithm and TableauE′algorithm, thus realizing the extension and consistency checking of Abox (assertion of individuals), and making up the deficiency of traditional DL.
