[0054] The present invention proposes a context-aware mobile application sorting method, the overall flow chart is as follows figure 1 As shown, the method is divided into three parts: acquiring semantic places, acquiring activities, and applying rankings. Among them, the acquisition of semantic places first collects GPS location information, and then clusters them into GPS visit locations, then extracts time pattern features from GPS visit locations to form GPS feature vectors, and finally uses GPS feature vectors to train semantic place classification models; The part collects the acceleration information first, then cuts it into acceleration frames, then extracts the statistical features and frequency domain features from the acceleration frames to form the acceleration feature vector, and finally uses the acceleration feature vector to train the activity classification model; the application sorting part first sets the sorting rules, Then obtain the user's current semantic...
