Treatment tutomatic: Semantics analysis and traduction of the frozen expression with Nooj

The purpose of this article is to define more closely the notion of freezing which, despite numerous publications in the field, remains a vague concept. The reflections are the result of a research project that aims to build an almost exhaustive database of fixed verbal expressions in English. After a review of the essential properties of the expressions, it is indicated why each of these criteria is problematic. One of the major problems lies in the existence of related phenomena: from a semantic point of view, fixed expressions participate in the general phenomenon of polysemy, lexical solidarity brings them closer to collocations and finally, morphosyntactic fixity is present in many fixed sentences that are conversational routines and even partly in so- called free syntax
