Impressions from ACM SAC 2010

The 25th ACM SAC conference was held in Sierre, Swiztherland, a very privileged area surrounded by the stunning Swiss Alps. Comparing to my previous attendance, it seems the number of attendees has decreased (maybe just an impression). On the other hand, the quality of works and the level of plenary discussion seem to be improved. Because the conference is multi-track, I could attend sessions of related areas to my current work such as data mining and semantic web.

Collaborative filtering is one of the most frequently used techniques in personalized recommendation systems. But currently used user-based collaborative filtering recommendation algorithm and the collaborative filtering recommendation algorithm based on item rating prediction has disadvantage in similarity computation method. Basing on this disadvantage, the paper puts forward an improved collaborative filtering recommendation algorithm.

RecSys '09: Proceedings of the third ACM conference on Recommender systems

Collaborative tagging systems pose new challenges to the developers of recommender systems. As observed by recent research, traditional implementations of classic recommender approaches, such as collaborative filtering, are not working well in this new context. To address these challenges, a number of research groups worldwide work on adapting these approaches to the specific nature of collaborative tagging systems.
