    <Paragraph position="0"> The two LTAG for French and Italian are easy to maintain, due to the hierarchical representation in MG. They can be customized for language domains, by cutting subgraphs of the inheritance network in MG.</Paragraph>
    <Paragraph position="1"> The MG for French is currently used to maintain the French LTAG. It has also been used to generate the tree sketches for the text generator G-TAG (Danlos &amp; Meunier, 96), based on TAG.</Paragraph>
    <Paragraph position="2"> The generator makes use of tree sketches characterization as a set of features ---called tfeatures- such as &lt;passive&gt;, &lt;infinitivalclause&gt;... This characterization has been straightforward to obtain with the representation of the tree sketches in MG.</Paragraph>
    <Paragraph position="3"> Further, the two MG for French and Italian can provide a basis for tranfer between syntactic structures for Machine Translation. LTAG elementary trees correspond to a semantic unit, with (extendable) positions for the semantic arguments if any. (Abeill6, et al, 90) propose to pair elementary trees for the source and target languages and to match in these pairs the argumental positions of the predicate. Once these links are established, the synchronous TAG procedure can be used for translation.</Paragraph>
    <Paragraph position="4"> The argumental positions correspondance is straightforward to state within the MG framework. We plan to define an automatic procedure of tree-to-tree matching using MG representations for source and target languages, once the initial functions of arguments are matched for pairs of predicates. This procedure will make use of sets of t-features to characterize tree sketches (as in G-TAG) derived at the MG---&gt;LTAG compilation time.</Paragraph>
    <Paragraph position="5"> Correspondances between t-features or sets of t-features have to be defined.</Paragraph>
