My joint work with Stefan Siersdorfer “How useful are your comments? – Analyzing and Predicting YouTube Comments and Comment Ratings” has been accepted as a full paper in the next edition of ACM Conference on the World Wide Web (WWW’10).
Find below the abstract of the submission:
An analysis of the social video sharing platform YouTube reveals a high amount of community feedback through comments for published videos as well as through meta ratings for these comments. In this paper, we present an in-depth study of commenting and comment rating behavior on a sample of more than 6 million comments on 67,000 YouTube videos for which we analyzed dependencies between comments, views, comment ratings and topic categories. In addition, we studied the influence of sentiment expressed in comments on the ratings for these comments using the SentiWordNet thesaurus, a lexical WordNet-based resource containing sentiment annotations. Finally, to predict community acceptance for comments not yet rated, we built different classifiers for the estimation of ratings for these comments. The results of our large-scale evaluations are promising and indicate that community feedback on already rated comments can help to filter new unrated comments or suggest particularly useful but still unrated comments.
After a quite intensive week, WWW has concluded and it’s seems a good time to look back and summarize the main activities and experiences. Though it was my intention to keep a dairy log of the events, the lack of time was much more important than I expected. So, let this late entry replace the originally planned ones 😉
Yesterday it was my turn for presenting our full-paper accepted into this year edition of ACM World Wide Web conference (WWW’09). The expectation for the “Photos and Web 2.0” session was far beyond the calculations of the organizers, and the room allocated for the talks was simply too small for all the people that showed up. Many had to see the first presentation of the session looking through the door while standing in the corridor. It was during the second presentation (my one) that they decided to remove the panels at the rear to merge with an empty room just behind. Though it was absolutely necessary I simply do not understand why they decided to do it right in the middle of my talk. I loss my concentration completely and it was difficult to re-start the talk again.
Despite the difficulties, the presentation went alright and it lead to a positive reaction from the audience which asked a good amount of interesting questions. The slides are available from the www2009 epapers website.
See you in Boston next July! Sigir awaits!
WWW started today with the round of tutorials and workshops that commonly precede such large conferences. I met again with some of the people I’ve been running into in the last few conferences I’ve attended and used the chance to receive an update from them. I also met with my former college Stefan Siersdorfer, co-author of the submission I got accepted into this conference.
