Notes

Abstract: We report a study on improving the retrieval of comments made to previous posts that can potentially be relevant to new posts in the open social media domain. This retrieval task, known as an important component of “short text conversation,” is challenging due to various reasons, among which is the fact that both posts and comments are usually very short, thus not providing enough context for typical information retrieval systems to be very effective. We used a “document expansion” technique to enrich each comment by adding terms contained in the post that the comment previously responded to. Our comparative evaluation experiment shows that while helpful in some cases, the technique hurt in some other cases. Initial analyses are discussed and future directions are outlined.
