| Summary: | The intense competition and high failure rate of product introduction necessitate a deeper understanding of customer needs for product design. The conventional process of interpreting customer statements relies on imprecise information, making it highly unlikely, if not impossible, to acquire accurate need statements for the front-end process of product development. To deal with this problem, an ontology-learning customer needs representation (OCNR) system is proposed in this paper. The system uses natural language processing tools to preprocess customer statements. The customer needs ontology is then established based on the key concepts and their relations that are extracted from the customer statements. A set of need statements are then generated using the established customer needs ontology. A word property-based method is proposed to extract more nontaxonomic relations. A case study was conducted to illustrate the proposed approach. Results of this study suggest that the customer needs ontology derived from the proposed OCNR system contains more semantics than those obtained from the existing ontology learning systems, and, therefore, might be able to generate more accurate need statements. |
