Study of LBS systems based on social software and complex information system
基于社会性软件和复杂信息系统的LBS服务体系研究

The LBS1.0 system based on linear system design separated relationships between users and system and the ones among users, the users accepted the functions provided by the system passively, consumed the data from the system and contri-buted little to system improving and data renewal. The novel LBS based on Mobile Web2.0 (LBS2.0)injected into concept of social software and complex information system, took advantage of the complex relationships between users and system, together with the ones among users, turning the user from an end of LBS system into a node of it and making the users from consumers of data into designers of system and reporters of data. LBS2.0 employed the element of Web2.0, emergence of a great deal of user self-organized behavior and collective intelligence to improve system adaption and data currency and accuracy. A great deal of high-accuracy and trustworthy data would promote a large number of spatial analyses and further applications of data mining with valuable result. It is proved in prototype systems that LBS2.0 is effective to improve data update efficiency and QoS of LBS system, and to better users experiences.
