Detecting Peer to Peer Insults

insulting in debates or discussion. For eg :-

discussion on any comment made by some

political leader.

Recommendation Challenges in WebMedia

• Traditional Content based recommendation and

Collaborative filtering has higher rate of false

positives.

• Recommendation based on social signals is also

not efficient and there is high probability

different likings between friends.

• Cold Start Problem:- How to recommend user

who is new to system

Comment Text Relevance

• How do we find comments/posts that are

relevant to the article?

• Can we rank all comments wrt relevance

• If not, can we atleast find the least relevant

comments, and use that signal to bump down a

comment that is otherwise of good quality?

• Can we find highly relevant comments, even if

they are very short?

Flickr Challenges

photo should be shown user to keep him

engaged.

• Creating implicit following graph in flickr based

on clicks on a user photo by someone
