Research On Construction Of Religious Thangka Image Knowledge Repository

The paper researches on Image-knowledge Repository for the Religious Thangka Image based on the high level semantic about the attributes that describe the mains in the pictures. According to the status and identity of the main in Tibetan Buddhism culture, their have several kinds of them, including Buddha, Patriarch, Bodhisattva, Yidam, Buddha Mother, Arhat, Dakini, Dharmapala, Genius God and so on. The attributes of mains are the domain knowledge that uses to establish the repository exactly, such as mains'name, headwear, appearance, complexion, mudra, talisman etc. Firstly, devise the conceptual data model of describing the mains depending on the attributes, show with relational schema of relational database. Secondly, build image libraries on the basis of the kinds, in accordance with the relational schema, use the non-automatic way acquiring knowledge, that is, devise a special knowledge editor to get knowledge, form various fact base for the kinds of mains and obtain fact knowledge for the Repository. Thirdly, select some attributes that can typically distinguish mains depending on the characteristics of the mains attributes as key attributes, adopt production rule knowledge representation method, save the key attributes to be conditions and names of mains to be conclusions, form rule knowledge for the Repository. At last, connect facts and rules by the process of knowledge query, combine forward reasoning control, and split strategies base in the light of the attribute of headwear, shape hierarchical conditions for production rule depending on execution sequence of key attributes for every strategy, take Structure Query Language of relational database to finish the reasoning work, provide strategy and rules in the process of reasoning and semantic introductions about the result image for users, construct the Religious Thangka Image Knowledge Repository finally.
