Etude expérimentale de la distribution des bordures de motifs fréquents

The discovery of the positive border of frequent itemsets (or maximal frequent itemsets) in a transactional database is a classic problem in data mining.

The distribution of word senses is one such important type of data, but still is uneasy to obtain. We are currently developing a system for analysing thematics aspects of texts and undertaking word sense disambiguation based on...
