It is time-consuming to build ontology-based knowledge base of customer requirements by hand. While the precision and recall of automatic building it is poor. In view of this situation, this paper researches the concept and scope of customer requirements and proposes a semi-automatic method of constructing customer requirements knowledge base based on data of e-commerce sites. In the first instance, the method builds the conceptual model of OWL-based customer requirements knowledge according to product categories by hand.
