【Abstract】 The acquisition or improvement of knowledge by learning is still one of essential issues in knowledge engineering. Inductive Logic Programming is such a learning method that makes use of background knowledge and learning examples in acquisition or improvement of knowledge. At present, the specialization of inductive hypotheses, one of main operations of the method, is limited to a few classes of inductive hypotheses and does not meet the principle of most generalization. Based on resolution and related to background knowledge and learning examples, this paper presents a theory of consistent specialization for the problem, which shows a way to construct the most general specialization of inductive hypotheses. This theory can be considered to be a general framework of theory specialization under logic implication. Furthermore, this paper sets forth, with the theory, a concept of k general specialization and corresponding algorithm to cope with the computability of the problem. The experiment shows that the theory specialization can be correctly and effectively computed with the theory and algorithm presented in this paper.更多还原
