摘要
讨论了本体与国际专利分类表的内在联系。在专利信息服务系统中,以国际专利分类表为基础,提出了符合专利信息特点的IPC本体;设计了采用本体检索与关键字检索有效结合的组合检索方式;增加了从企业用户信息中提取出的用户兴趣模型。把用户兴趣模型转化为符合系统检索规则的检索条件加入到原组合检索中,进一步缩小检索范围,在一定程度上提高了专利信息检索的查全率和查准率。
Discusses the inherent relation between ontology and international patent classification. On the basis of international patent classification, the Patent Information Services System puts forward a IPC ontology which addresses the characteristics of patent information, and combines the ontology with keywords retrieval, and adds user＇ s interest model which extracts from corporation information. This model translates to condition which is true of the retrieval regular of system and joins the combined search mode formerly. This reduces the bound of searching and improves the recall and the precision of patent information retrieval.
