The very complex **data** organization is usable by specialists but not by ordinary users. That is why we have been interested by the realization of a flexible and intelligent system, which allows the consultation and comparaison of the two languages lexicongrammars (which are at the present day romance languages lexicon-grammars), and which includes the correspondance notion we have just presented. Its use will not need any knowledge neither of the **data** organization nor of computer science.
