AN AUTOMATIC FILTERING TASK IN OSN USING CONTENT BASED APPROACH

In Online Social Network, information filtering can be used for different and more responsive function s. This is owing to the fact that in OSN there is the possibility of posting or commenting other posts on particular public or private regions called general walls. Information filtering can be used to give users the ability to control t he messages written on their walls automatically, by filtering out unwanted messages. OSN provide very little support to prevent unwanted messages on user walls. For instance Facebook permits users only to state who is allowed to insert mes sages in their walls. (friends, friends of friends, group of friends).
