Hello everyone, I need your help!Recently, i met a problem that how i can get the similar users by quering with a known user id in UR template. Actually, i want to build a friend group whose users have the high similarity. As far as i understand, UR can realize user-CF based on the similartiy of different users. Thus, pio need know the relative similarity of each user. Am i wrong to think along with this direction?Thanks for your any answers and ideas.Thank you !winboy Guo
