evaluate whether the object is good or bad This paper builds set labels to identify the comparison sentences in the Vietnamese comments in a specific domain (website selling mobile phones) and the collective label for comparison used to analyze the emotions of users based on their comments The construction is carried out gradually by analyzing data of a specific domain, and applying special programs to processing language and by referring to the rich vocabulary of the Vietnamese emotional dictionary in order to arrive at highly accurate results of analysis The effectiveness of this method is manifestedthrough an application program which is built to evaluate the accuracy of the collective label in determining comparison sentences of Vietnamese comments Key words: label, comparative/comparison, emotions, positive points, negative points.stu DAT VAN DE Su gia tang ciia cac thiSt bi su dung web cho phep nguoi co th6 giao tiep voi cong dong web bang nhieu hinh thiic khdc
