Abstract: To obtain the accurate requirements of remanufacturing service for realizing service composition and completing service process,aiming at the difficulties in implicit-requirements acquisition caused by customers' individual differences and limitations in their cognitive processes,a dynamic requirement acquisition strategy was put forward.To improve the efficiency and accuracy of requirements acquisition,a dynamic requirements acquisition method for remanufacturing service based on ontology learning was proposed with reference to ideas of manufacturing resource ontology modeling and ontology learning.By combining with the characteristics of remanufacturing and its services,the candidate ontology and semantic expression model of remanufacturing service were established.On this basis,the ontology of certain remanufacturing service requirements was constructed through Web effective block division,similarity computation,content extraction and so on.An application example was given to verify the validity and practicability of the method.
