Method of credal network approximation inference based on extended relational data model

QU Ying1,2,WU Qi-zong1,LI Ping11.School of Management and Economics,Beijing Institute of Technology,Beijing 100081,China 2.School of Economics and Management,Hebei University of Science and Technology,Shijiazhuang 050081,China  
The extended relational data model is extended with the two operators of extended product join and extended marginalization defined.A method to make Credal network approximation inference is proposed by computing the joint probability distribution and posterior probability of variables through the above operators.Furthermore its arithmetic is developed by SQL statement.Its validity and efficiency can be showed in the application case.The relational data structure of Credal network is constructed.Thus the query optimization mechanism of relational database can be fully used and the efficiency of Credal network inference can be improved greatly.
