Une étude de la coordination des propositions avec ellipse en français : formalisation et application avec XLFG

In this study, we try to examine sentential coordination with ellipsis in French in two problematic cases: Right Node Raising and Non-constituent Coordination. The main goal of the implementation that we propose in XLFG will be to provide us more leeway in comparison with the usual LFG analyses, while confronting our proposal with an experimentation and the rigour aspect of an automatic system. However, we propose an analysis compatible with the LFG theory, which will rehabilitate two traditional ideas of syntax: (i) that coordination conjunctions are at the head of the coordination, (ii) the deleted element is interpreted according to the context.
