  1. Computational Parallels Across Language Modules

    Graf, Thomas

    Abstract Linguists study a variety of aspects of language, including phonology, morphology, and syntax. It is commonly believed that those are distinct modules of language, governed by very different principles and consequently studied with very different tools. While there have been attempts at …

  2. Morphotactics as Tier-Based Strictly Local Dependencies

    Aksënova, Alëna, Thomas Graf, and Sedigheh Moradi

    Abstract It is commonly accepted that morphological dependencies are finite-state in nature. We argue that the upper bound on morphological expressivity is much lower. Drawing on technical results from computational phonology, we show that a variety of morphotactic …

  4. Models of Adjunction in Minimalist Grammars

    Graf, Thomas

    Abstract Three closely related proposals for adding (cyclic) adjunction to Minimalist grammars are given model-theoretic definitions and investigated with respect to their linguistic and formal properties. While they differ with respect to their linguistic adequacy, they behave largely the same on a computational …

  6. Beyond the Apparent: Cognitive Parallels Between Syntax and Phonology

    Graf, Thomas

    Abstract One of the central changes in 20th century linguistics was the reconceptualization of language as a cognitive ability rather than merely an abstract relational system of signs —- in the terminology of Chomsky (1986), the move from E-language to I-language. This shift entails …

  7. Locality and the Complexity of Minimalist Derivation Tree Languages

    Graf, Thomas

    Abstract Minimalist grammars provide a formalization of Minimalist syntax which allows us to study how the components of said theory affect its expressivity. A central concern of Minimalist syntax is the locality of the displacement operation Move. In Minimalist grammars, however, Move is …

  9. Logics of Phonological Reasoning

    Graf, Thomas

    Abstract Inspired by Kracht (2003) and Potts and Pullum (2002), who use tools from mathematical logic in their investigation of phonological theories, I develop an extendable modal logic over string structures, which in turn is used to formalize a specific phonological theory, Government …

  10. Comparing Incomparable Frameworks: A Model Theoretic Approach to Phonology

    Graf, Thomas

    Abstract In previous work, we used techniques from mathematical logic and model theory to study and compare two phonological theories, SPE and Government Phonology. The surprising result was that Government Phonology corresponds to a very weak fragment of SPE, yet it can attain …

  11. Towards a Factorization of String-Based Phonology

    Graf, Thomas

    Abstract Inspired by the model-theoretic approach to phonology deployed by Kracht (2003) and Potts and Pullum (2002), I develop an extendible modal logic for the investigation of phonological theories operating on (richly annotated) string structures. In contrast to previous research in this vein …
