外文摘要：This paper proposes a data-mining algorithm based on ontology by contrast with the traditional ones。 It can mine data on the high-level or multi-levels。 The algorithm is based on the domain knowledge that the ontology describes。 By using of the decision tree category algorithm in data mining， it can extract the ontology at different levels according to the gain of attribute measurement to produce high-level categorizing rules and optimize them。
