Abstract:
In Optimality Theory, a set of grammatical constraints defines
a space of possible languages. This space is called the
factorial typology. In this paper, we note that every factorial
typology defines a t-order, i.e. a set of implicational
universals that hold among <input, output> pairs. T-Order
Generator is a Windows program that generates t-orders.
The input to the program is a factorial typology; the output
is a t-order visualized as a directed graph. This structure
has a useful application in the study of variation: it imposes
universal limits on the quantitative variation permitted
by a constraint set. These limits hold under several theories
of variation, including Multiple Grammars, Partially Ordered
Grammars, and Stochastic Optimality Theory.
