  1. An Alternate View on Strong Lexicalization in TAG

    De Santo, Aniello, Alëna Aksënova, and Thomas Graf

    Abstract TAGs were recently shown not to be closed under strong lexicalization but to be strongly lexicalizable by context-free tree grammars of rank 2. This paper presents an alternative lexicalization procedure that builds on an earlier generalization …

  2. Some Interdefinability Results for Syntactic Constraint Classes

    Graf, Thomas

    Abstract Choosing as my vantage point the linguistically motivated Müller-Sternefeld hierarchy (Müller and Sternefeld 2000), which classifies constraints according to their locality properties, I investigate the interplay of various syntactic constraint classes on a formal level. For non-comparative constraints, I use Rogers’ (2003 …

  3. Locality in Flux —- Reducibility Results for Syntactic Constraints

    Graf, Thomas

    Abstract Müller and Sternefeld (2000) propose a locality hierarchy of syntactic constraints such that {representational, derivational} < global < translocal < transderivational. We use formal methods to demonstrate that their hierarchy correctly assumes that higher constraint classes are more powerful, but we also show that for …
