Characterizing Users in an Online Classified Ad Network
Muhammad Waqar, Davood Rafiei · 2016
Unlike online social networking sites (e.g. Twitter and Facebook) which are heavily used for disseminating content and sharing information between users and shopping sites (e.g. Ebay) where buyers and sellers are reviewed, the flow of information between users such as buyers and sellers in a classified ad network is very limited. Characterizing users or assigning them to some classes in one such network is challenging due to the sparsity of the data about users, the vague separation of user classes and sometimes the tendency of users to hide or misrepresent their profile information.
