With the coming of 3G ages and the high-speed growth of Web resources, there is a trend of rapid development in mobile Internet, making resources accessesible and information obtainable conveniently by using mobile devices. However, in mobile Web search, these are very challenging tasks to geo-tag Web resources, integrated spatial data and Web data seamlessly, and provide valuable and high-relevant information to users. A framework of mobile Web search is proposed in this paper, and the key research techniques in mobile Web search are classified and surveyed according to this framework. Based on the comprehensive comparison and analysis of existing techniques, the suggestions for future research are put forward.%随着3G时代的到来和Web资源的飞速增长,移动互联网呈现出快速发展的趋势,人们可以利用移动终端设备便捷地访问网络,从中获取丰富的信息.然而如何对Web资源进行地理标记,并将地理数据与Web数据进行无缝集成,为移动用户提供有价值的高度相关的信息,却都是十分具有挑战性的工作.提出了一个移动Web搜索的系统框架,依据该框架对移动Web搜索领域关键性技术进行了分类概括总结.在对已有技术进行深入对比分析的基础上,指出了该领域未来的研究工作和面临的挑战.
