Violation Semirings in Optimality Theory
This paper provides a brief algebraic characterization of constraint violations in Optimality Theory (OT). I show that if violations are taken to be multisets over a fixed basis set Con then the merge operator on multisets and a ‘min’ operation expressed in terms of harmonic inequality provide a semiring over violation profiles. This semiring allows standard optimization algorithms to be used f...
متن کاملOptimality Theory and Vector Semirings
As [5] and [11] have shown, some applications of Optimality Theory can be modelled using finite state algebra provided that the constraints are regular. However, their approaches suffered from an upper bound on the number of constraint violations. We present a method to construct finite state transducers which can handle an arbitrary number of constraint violations using a variant of the tropic...
متن کاملLearnability in Optimality Theory
In this article we show how Optimality Theory yields a highly general Constraint Demotion principle for grammar learning. The resulting learning procedure specifically exploits the grammatical structure of Optimality Theory, independent of the content of substantive constraints defining any given grammatical module. We decompose the learning problem and present formal results for a central subp...
متن کاملOptimality Theory in Phonology
GENERATIVE PHONOLOGY [q.v.] aims to construct a predictive theory of natural language sound systems, rooted in a finely-detailed account of the principles defining linguistic representations and the possible relations between them. Within these broad goals, OPTIMALITY THEORY (OT) develops in the context of specific empirical theses about the way phonological systems are organized. We identify t...
متن کاملTypology in Optimality Theory
The mechanism of constraint re-ranking basis makes Optimality Theory (OT) a typologically oriented theory of phonology. Permuting the prioritization of constraints on a language-specific basis generates a factorial typology of phonological patterns. Patterns generated by an optimality-theoretic account can be compared with the set of attested patterns found in languages of the world to determin...
