Basic MatrixAs presented above, the ME deduction is based on the basic matrix constructed from the targetsentence and all sentences in the initial knowledge base. The larger the basic matrix is, ... presents a methodof reducing the size of the basic matrix in the pointed probabilistic reasoning via ME. Our approachis to construct the basic matrix of the sentences in the related layers without...
