Direct parsing with metarules
Wilhelm Weisweber, Susanne Preuß · 1992
In this paper we argue for the direct application of metarules in the parsing process and introduce a slight restriction on metarules. This restriction relies on theoretical results about the termination of term-rewrite systems and does not reduce the expressive power of metarules as much as previous restrictions. We prove the termination for a set of metarules used in our German grammar and show how metarules can be integrated into the parser.
