Content-Based Filtering in On-line Social Networks

Abstract. This paper proposes a system enforcing content-based message filter-ing conceived as a key service for On-line Social Networks (OSNs). The system allows OSN users to have a direct control on the messages posted on their walls. This is achieved trough a flexible rule-based system, that allows a user to cus-tomize the filtering criteria to be applied to their walls, and a Machine Learning based soft classifier automatically producing membership labels in support of content-based filtering.
