Abstract: Aiming at shortages of Chinese knowledge retrieval in the computer-aided product innovation system, a knowledge retrieval method based on coreference index was proposed. Three-layer mapping structure “coreference index function ontology-design knowledge” was put forward to represent design knowledge, and then guided by coreference index, face-to-face knowledge architecture was established with retrieval ontology as the core. Through analyzing designers searching intentions which described with natural language, retrieval verbal noun word pairs were obtained. Using similarity weight between conceptual terms calculated by mutual information technology, function ontology complying with retrieval intention was matched and design knowledge was retrieved with constructed functional basis. Finally, an example in Knowledge Retrieval Prototype System was used to reveal the feasibility of retrieval method.
