The similarity measure of user behavior based on behavior sequence had not considered the semantic similarity index of activity.To solve this problem,a new algorithm of user behavior similarity measurement was proposed which supported activity semantics.Specifically,the similarity of activities was calculated by combining adjacency relation with label text semantics between activities;the edit weight function and the behavior sequence distance were defined;the users' behavior was modeled with behavior seque...
