Talking to the crowd: What do people react to in online discussions?
This addresses the problem of understanding user engagement in online discussions for researchers and platform designers, but it is incremental as it builds on existing sentiment and feature analysis.
The paper tackled how language use influences community reactions in online forums by analyzing Reddit comments with karma scores, finding that the importance of language features varies across different subreddits.
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.
