Intelligent Database Systems Lab N.Y.U.S.T. I. M. Motivation advertiser wants to avoid content relating to war, violence, pornography, etc. advertiser wants to detect and avoid negative opinion about their product when positive, negative and neutral sentiments co-exist on a page.
4
Intelligent Database Systems Lab N.Y.U.S.T. I. M. Objective This paper proposed a classifiers to distinguish the content whether it is positive or not for a set of advertisements and web pages
5
Intelligent Database Systems Lab N.Y.U.S.T. I. M. Methodology SENSITIVE CONTENT DETECTION : advertising do not want their ads to be shown on web pages that contain those sensitive contents.

Intelligent Database Systems Lab N.Y.U.S.T. I. M. Conclusion 11 We showed that the MILBoost system is able to improve on the performance of the traditional classifiers in such tasks, especially when the percentage of mixed content is high. Unfortunately, it do not have sentence-level labels therefore the evaluation can only be done at the page-level.
