چکیده

A typical discussion thread in an online forum spans multiple pages involving participation from multiple users and thus, may contain multiple view-points and solutions. A user interested in the topic of discussion or having a problem similar to being discussed in the thread may not want to read all the previous posts but only a few selected posts that provide her a concise summary of the ongoing discussion.

Proposed approach is evaluated using two real life forum datasets.
