摘要
阐述了两种LBS位置表示方法,引入了语义位置的概念,对现有的语义位置概念作了修正,强调了位置属性也是语义位置的重要组成部分。通过对位置概念内涵和外延的分析,讨论了位置属性所包括的内容;运用层次建模,实现了位置之间关系的描述。为了能够规范化地描述语义位置,运用本体技术,对位置所包含的语义信息进行了描述,建立了能够被计算机识别和处理的OWL位置本体模型。通过对语义位置的本体建模,实现了位置信息的知识化描述,为实现个性化服务奠定了基础。
Started by simple presentation of location determination techniques, physical location and geographic location as two common kinds of location description methods are dis cussed, Semantic location concept is introduced followed. This paper has given a correction to this concept. By analyzing the connotation and extension of every geographic location, what should be contained in location property is determined. Using hierarchy model, the re lations and associations among the locations are clearly described, In order to realize formalized description of semantic location, ontology technique is used. The location ontology model realizes the knowledge description of location information and establishes an important foundation for personalized preference services in LBS.
