    <Paragraph position="0"> The paper illustrates how RG can be used to map in a principled way surface dependency relations into thematic roles.</Paragraph>
    <Paragraph position="1"> 3 '/'he Goal relation, such as Instrument or Location, is a non-term relation and participates only to special kinds of promotional rules (see \[Perlmutter 83\] for details).</Paragraph>
    <Paragraph position="2"> The main feature of the approach is the strict cooperation among different knowledge sources (lexicon, RG rules and semantics) in carrying out the task: this cooperation is made necessary by the partial configurationality of Italian, where the ordering of constituents can only be considered as the basis for plausible suggestions, but not as the source of stricts constraints. The adoption of an unmarked input (an unlabelled dependency tree) makes available a flexible starting point that leaves the RG module the task of making the required inferences.</Paragraph>
    <Paragraph position="3"> The ideas expressed herein are implemented in the GULL system (see \[Lesmo, Torasso 83, 85al for the syntactic part \[Di Eugenio, Lesmo 871 for the basic ideas about semantics): both levels of grammars are represented via condition-action rules. The system is implemented in Common Lisp and runs on SUN workstations.</Paragraph>
