Unifying collaborative and content-based filtering

Twenty-first international conference on Machine learning - ICML '04, 2004
Collaborative and content-based filtering are two paradigms that have been applied in the context of recommender systems and user preference prediction. This paper proposes a novel, unified approach that systematically integrates all available training information such as past user-item ratings as well as attributes of items or users to learn a ...

Content based SMS spam filtering

Proceedings of the 2006 ACM symposium on Document engineering, 2006

Breaking and fixing content-based filtering

2017 APWG Symposium on Electronic Crime Research (eCrime), 2017
We demonstrate a vulnerability in existing content-based message filtering methods, showing how an attacker can use a simple obfuscator to modify any message to a homograph version of the same message, thereby avoiding digest and signature based detection methods.
