  Abstract: What characterize influence and influential users in online health communities (OHCs)? Through sentiment analysis of users’ posts, we revealed sentiment dynamics and influence in threaded discussions. A novel, intuitive and effective metric was proposed to identify influential users in such communities. Further analysis also found the “when”, “what”, and “who” factors related to sentiment influence in OHCs.
