移动用户兴趣点标记语义映射方法

针对当前移动用户兴趣点标注没有统一的语义本体这一问题，通过对移动用户兴趣点分类，建立了 POI概念本体层次树，将用户标注的POI信息与本体树节点通过一种改进的映射方法建立映射关系，为移动用户标注信息提供统一的规范化语义。实验收集多名志愿者5周的真实标注信息来评价该方法，实验结果表明该方法具有较高的准确率。

Semantic Mapping Method on the Mobile Users' Point of Interest

In view of the problem that marked the POI (Point of interest) of the current mobile users with no unified semantic ontology,this paper categorized POI and established POI ontology hierarchy tree for mobile users, then finished the mapping between the labeled POI information of users and the node of ontology tree by an improved mapping method to provided a unified standardized semantics for mobile users to mark information. An experiment is performed to evaluate the performance of the new similarity measure by using the labeled information of users in a period of 5 weeks, the results show that the method has high accuracy.
