Our main field of research is the statistical exploration of qualitative and textual data (Data and Text Mining). The leading case could be a very large sample survey data set comprising both closed-end and open ended question. Those statistical processing, upstream of most statistical modelling techniques, concern mainly large arrays of qualitative data and large corpora of textual data. These works consist of conceiving new techniques of visualization and clustering together with the corresponding validation or assessment tools, scrutinizing their uses and (possible, probable) misuses.
