Abstract:Bidirectional Optimality Theory allows us to see a wide
range of problems which would previously have been considered
unrelated from a new perspective, the perspective of asymmetric
relationships between input and output. For interpretation, the
input is a form and the output a meaning, and for production
the input is a meaning and the output is a form. A mismatch is
any case where there is no isomorphism between the space of meanings
and the space of forms, say because one form has no meaning
(uninterpretability), or multiple meanings (ambiguity), or because
a meaning is inexpressible,(ineffability) or may be expressed in
multiple ways (optionality). In this paper, we study architectural
aspects of four versions of bidirectional OT so far proposed,
and their treatments of these form-meaning asymmetries. The four
models to be studied here are the strong and weak bidirectional
OT of Blutner (2001), and the asymmetric OT models of Wilson (2001)
and Zeevat (2001). We show that each of these models provides at
best a partial solution to the problems of form-meaning asymmetry.
We also discuss some possible directions in which these existing
proposals could be developed so as to model cases of form-meaning
mismatches that they fail to account for.
