Through the discussion of IETM intelligent semantic retrieval method, an IETM intelligent semantic retrieval method based on Jena reasoning is proposed. The shortcomings of the current IETM system retrieval method are analyzed, and it is proposed that semantic retrieval is an effective way to realize IETM intelligence. The basic principles of Jena semantic reasoning are elaborated in detail. Finally, an IETM intelligent semantic retrieval method based on Jena reasoning is designed. This method performs Jena reasoning in the IETM domain ontology library according to the input retrieval semantic retrieval conditions to obtain semantically extended retrieval results; and searches in CSDB according to the semantically extended retrieval results to obtain the final results. The proposed method better meets the requirements of intelligent retrieval of massive domain knowledge in the IETM system and the needs of user diversity, emphasizes the recall rate and precision rate of retrieval, and effectively overcomes the semantic missing problem of traditional keyword retrieval model.
