What is a constraint in linguistics?
The notion of constraints is generally used in modern linguistics (in particular in syntax and phonology) for representing properties that an object must satisfy (see , ). In all cases, the idea consists of stipulating properties ruling out structures which don’t belong to the language.
What is theory of optimality in DAA?
The principle of optimality is the basic principle of dynamic programming, which was developed by Richard Bellman: that an optimal path has the property that whatever the initial conditions and control variables (choices) over some initial period, the control (or decision variables) chosen over the remaining period …
How is freedom of analysis related to Optimality Theory?
Gen is free to generate any number of output candidates, however much they deviate from the input. This is called freedom of analysis. The grammar (ranking of constraints) of the language determines which of the candidates will be assessed as optimal by Eval. In Optimality Theory, every constraint is universal.
What are the roles of Marks and faithfulness in Optimality Theory?
Each plays a crucial role in the theory. Markedness constraints motivate changes from the underlying form, and faithfulness constraints prevent every input from being realized as some completely unmarked form (such as [ba]).
How does optimality theory differ from other phonology approaches?
Optimality Theory. OT differs from other approaches to phonological analysis, such as autosegmental phonology and linear phonology (SPE), which typically use rules rather than constraints. OT models grammars as systems that provide mappings from inputs to outputs; typically, the inputs are conceived of as underlying representations,…
Which is the universal constraint in Optimality Theory?
The grammar (ranking of constraints) of the language determines which of the candidates will be assessed as optimal by Eval. In Optimality Theory, every constraint is universal. Con is the same in every language. There are two basic types of constraints:
