A Machine Learning Approach to Filter Unwanted Messages from Online Social Networks

Online Social Networks, also called as social networking sites, have gained popularity in recent years. A major issue in today’s online social networks is that the users don’t have direct control over the messages posted on their walls. So to prevent unwanted messages being posted on the user wall, a Filtered Wall is used which automatically filters the unwanted messages. Also the message posted on the walls is short text messages, a machine learning based text categorization technique is exploited to automatically assign with each short text messages a set of categories based on its content.
