[Abstract]:[objective] to provide a design framework for data acquisition and analysis in mobile environment based on situational awareness technology (Context Awareness). In order to optimize the automatic acquisition process of mobile data. [application background] although scenario sensing data acquisition based on mobile end has developed compared with manual and semi-automatic methods in traditional network environment, However, real-time user information can be directly obtained by using mobile end bottom sensor to realize real-time, dynamic and comprehensive data acquisition and mining to achieve the purpose of actively providing services. The application of this aspect is still in the developing stage. [methods] A data acquisition framework is designed based on Android sensors, which is automatically collected by the client and actively received by the server. In the aspect of demonstration and evaluation, an example is designed to recommend high-level services through dynamic situational awareness. [results] the empirical results show that the system can collect mobile user data for a given situation. To provide good support for high-level referral services. [limitations] the data collected have greater redundancy, without multi-angle, comprehensive, in-depth situational reasoning, It is necessary to analyze the user data deeply in the future research. [conclusion] the automatic mobile data acquisition system based on situational perception can collect mobile data actively and push service to individuals or groups according to the result of collection. It plays a good supporting role in the research of user behavior and situational computing in mobile environment.
