摘要
位置是实现位置服务的基础,语义位置模型从语义的角度描述与组织位置信息,能够更好地反映位置的全部特征,因而正逐渐成为位置服务的研究热点。鉴于目前语义位置模型存在研究内容不明确、形式化表达不具体和难以实际应用的问题,本文重点剖析了语义位置的内涵,详细描述了基于本体的语义位置逻辑结构及形式化表达,并建立了基于商场的语义位置模型。
Location is the base of location service,semantic location model has become a hot issue in location service,because it can describe and organize location information in a semantic view,and reflect all characters.Whereas due to the problems on semantic location model including：uncertain contents,undefined formal expression,and hard to be applicable,this paper stressed on the connotation of semantic location,and described its logistic configuration and formal expression based on ontology.At last,it constructed the semantic location model based on marketplace.
