Abstract:
This paper presents a probabilistic method for classifying folksonomy users to folksonomy sub-domains and identifying their par- ticular interests. In particular, we propose a method for mining topic hi- erarchies that may reveal either the collective or the user-specific concep- tualization of those domains, as these are reflected by users’ tags. We then propose two alternatives for identifying users’ interests in the domains: The first exploits users’ tags directly, and the second exploits users’ spe- cific conceptualizations of each domain. Both approaches use the col- lective domain conceptualizations as “reference”, to which users’ tags and conceptualizations are compared. The proposed statistical method is parametric-less and does not require any prior knowledge or exter- nal resources. We apply the proposed method on the Del.icio.us online bookmarking system and we provide experimental results.
