  1. Case Assignment in TSL Syntax: A Case Study

    Vu, Mai Ha, Nazila Shafiei, and Thomas Graf

    Abstract Recent work suggests that the subregular complexity of syntax might be comparable to that of phonology and morphology. More specifically, whereas phonological and morphological dependencies are tier-based strictly local over strings, syntactic dependencies are tier-based strictly …

  2. The Surprising Simplicity of Syntax: Derivation Trees, Subregular Complexity, and What It Implies for Language and Cognition

    Graf, Thomas

    Abstract It is a well-known fact of computational linguistics that syntax is mildly context-sensitive and thus highly complex —- certainly more complex than phonology or morphology. This complexity is at odds with the ease of language acquisition and the impressive speed of human sentence …

  3. C-Command Dependencies as TSL String Constraints

    Graf, Thomas, and Nazila Shafiei

    Abstract We provide a general formal framework for analyzing c-command based dependencies in syntax, e.g. binding and NPI licensing, from a subregular perspective. C-command relations are represented as strings computed from Minimalist derivation trees, and syntactic dependencies are shown …

  5. Adjunction to Movement Paths: Floating Quantifiers as the Little Brother of Parasitic Gaps

    Graf, Thomas

    Abstract A lot of recent work in computational phonology seeks to pinpoint the complexity of phonotactic dependencies from a formal perspective. Numerous mathematical classes have been proposed, but Graf (2017) subsumes them all under the umbrella of interval-based strictly piecewise dependencies (IBSP). IBSP …

  6. Tiers and Relativized Locality Across Language Modules

    Graf, Thomas, Alëna Aksënova, Hyunah Baek, Aniello De Santo, Hossep Dolatian, Sedigheh Moradi, Jon Rawski, Suji Yang, and Jeffrey Heinz

    Abstract Heinz and Idsardi (2013) draw attention to a profound computational difference between syntax and phonology: phonology only requires regular computations over strings (Johnson 1972 …

  7. Graph Transductions and Typological Gaps in Morphological Paradigms

    Graf, Thomas

    Abstract Several typological gaps have attracted a lot of interest in the linguistic literature recently. These concern the Person Case Constraint and the absence of ABA patterns in adjectival gradation, pronoun suppletion, case syncretism, and singular noun allomorphy, among others. This paper is …

  9. Do We Need Features for Morphosyntax?

    Graf, Thomas

    Abstract Bobaljik & Sauerland’s *ABA and the Combinatorics of Morphological Features attempts to explain the absence of ABA patterns across languages in terms of feature combinatorics. Their approach marks a step in the right direction by focusing on the algebra underlying the feature …

  10. Commonality in Disparity: The Computational View of Syntax and Phonology

    Graf, Thomas, and Jeffrey Heinz

    Abstract Heinz and Idsardi (2013) draw attention to a computational difference between syntax and phonology established by earlier research: phonology only requires regular computations over strings (Johnson 1972, Kaplan and Kay 1995), whereas syntax involves non-regular computations over strings (Chomsky …

  11. 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 …
