This is one of these moments that, despite being expected for a long time, end up really impacting you when they finally arrive. Steve Jobs passed away today. I am not the kind of person who like to exalt individual characters. It is always the case that behind the character there is always a group of people that help realizing their dreams. I am not even a long term mac advocate, nor a fanboy. I started using mac back in 2002, when OSX was mature enough and I was getting increasingly tired of the other OS alternatives. And I will of course change again when the alternatives catch up and surpass what Apple provides nowadays.
According to the Apple App Store statistics, we sold our 1000th copy of RAEplus just yesterday. As you know, RAEplus is MadIdeas‘ application to access the Normative Dictionary of the Spanish Language. After a somewhat slow start, the sales trend has been growing steadily allowing us to reach this milestone sooner than we expected.
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.
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!
