摘要
位置服务的核心是基于用户位置实现感兴趣信息的智能化推送,这已成为构建智慧城市和实现智能交通等方面的重要基础支撑。本文为提高位置服务信息的完整性和实时性,以泛在信息为数据源,通过分析主要的位置信息类型及其相似度评价方法,建立了面向位置服务的泛在信息聚合机制,对促进位置服务向精细化和智能化发展具有一定的应用价值。
The core of LBS is the intelligent push of information of interest based on the user location,and it is an important and basic support for building a smart city and realizing the smart transportation.In order to improve the integrity and real-time performance of LBS information,a ubiquitous information aggregation mechanism for LBS is established by analyzing the main types of location inforaiation and their similarity evaluation methods with the ubiquitous information as the data source t which has certain application value to promote the refined and intelligent development of LBS.
