Abstract/Summary

In the present paper we will analyze mapping operations as modelled in transformational generative grammar, as part of a more general inquiry into the limits of algorithmic approaches to natural language structure. Building on previous works, we propose a kind of system in which structure assignment proceeds by local domains and only assigns the computationally simplest structural description which captures syntactic- semantic dependencies within these domains. We will also present some prospects for an approach to structure mapping that is compatible with computationally mixed derivations.
