Talking to the crowd: What do people react to in online discussions?

Abstract

This paper addresses the question of how language use affects community reaction to comments in online discussion forums, and the relative importance of the message vs. The messenger. A new comment ranking task is proposed based on community annotated karma in Reddit discussions, which controls for topic and timing of comments. Experimental work with discussion threads from six subreddits shows that the importance of different types of language features varies with the community of interest.
