摘要
为能够及时搜索到网上订单业务,给出了基于领域本体实现查询关键字的语义扩展,通过查询向量与文档向量的相似度计算对检索结果进行排序的智能检索模型,建立了面向网上订单搜索的领域本体,由用户参照领域本体选择查询关键字,赋予查询关键字相应的权值,并应用智能检索模型实现了面向具体应用领域的智能检索.该方法保证了查询的查全率和准确率.
In order to search for to the online order business in time, the semantic extensions of domain ontology keyword based query were outlined. By comparing the similarity of query vector and document vector,which is the sorted result of intelligent search, Web order search oriented domain ontology were constructed. Allowing user to select query key words by referring domain ontology, assigning weight for each query command and applying intelligent search model onto the domain, intelligent search for a parti- cular domain was implemented. This method ensured that the entire search query and accuracy.
