The inference dependence graph is defined to get the logic expressions of sensitive RDF(S) triples. The candidate and optimal answers of the inference control problem are obtained by translating the logic expressions into the disjunctive normal form. Experiments show that this algorithm can prevent illegal inference and minimize the loss of semantic effectively.
