Mechanical Product Concept Extraction Method

Extracting product concept is the foundation to establish the model of mechanical product knowledge representation based on ontology. User demand documentation contains a number of domain knowledge. In allusion to this characteristic, the paper, using improved domain concept acquisition method of domain relevance and domain consensus, acquires machine concepts from requirements book of mechanical design domain automatically, to set up a complete mechanical knowledge expression model. Experiment results show that this method has good effect.
