摘要： Scenario aware computing is an important technology to realize precise information service in agricultural technology extension. This paper constructs a scene data fusion user perception of precision agricultural extension service. This paper established user classification model and multi situational awareness recommendation model based on multiple-factor, and realized the intelligent push services in personalized information. In comparison to common retrieval system which did not have the situational awareness and the intelligent push functions, the personalized information services based on situational awareness calculation was able to identify and predict the preferences of user interest, provided the psychological content for users. The correlation of personalized information services and resource push based on situational awareness calculation increased on average by 2.22 times, the accuracy rate increased by 1.34 times, meeting the user's personalized needs.
