Abstract: According to the semi-structured products page data in E-commerce website,a representation and construction method for product requirements knowledge'based on ontology was proposed,which included concept model,knowledge base template and knowledge acquisition.In concept model,a mapping method was designed from presentation of product requirements formalization to knowledge representation based on OWL descriptive language ontology;in knowledge base template,two kinds of representation was proposed to divide knowledge base template'structure into logical structure and collection point;for knowledge acquisition,a E-commerce website page templates extracting method was proposed based on wrapper induction.The feasibility and effectiveness of the method were proved by example of mobile website knowledge base system.
Key words: product knowledge base, e-business website, ontology construction, data extraction
摘要: 针对电子商务网站中半结构化的产品网页数据,提出一种基于本体的产品需求知识表示及构建方法,包括概念模型、知识库模板和知识获取三部分。在概念模型中设计了从产品需求形式化表示到基于Web本体描述语言的知识表示的映射方法;在知识库模板中提出了将其结构分为逻辑结构和采集点的两类表示方式;针对知识获取,提出了基于包装器归纳的电子商务网站网页模板抽取方法。通过某电子商务网站手机产品知识库的构建,验证了所提方法的正确性和有效性。
