Abstract

Social tagging is a well known approach of assigning keywords to (web) documents in order to share the personal meaning of users about the content. However, the ambiguity of the assigned keywords hinders the knowledge sharing process. In this paper we present an approach for supporting tagging process by interpreting the keywords (tags) using a conceptual Tag model, which leads to a semantic tagging process. Moreover, the approach introduces the tag refinement process that proposes extensions of given tags in order to help the user to better express his/her "tagging" need. We present several evaluation studies in order to demonstrate the efficiency of the approach.
