Research topics

My research interests lie in the fields of artificial intelligence, machine learning and data mining. More precisely, I'm working on topic/concept extraction from various kind of data. To this end, I develop new clustering techniques that are able to deal with sparse datasets. I'm also interested in tracking the topic/concept over time and in evaluating their quality. A lot of applications can be addressed, especially for data mining and social media analysis. I'm also very motivated by studying the links with other fields, such as psychology and sociology.

Keywords: artificial intelligence, machine learning, data mining, conceptual clustering, topic learning, (text+web+opinion) mining, social media analysis, role discovery, applications to digital humanities.
