- - - - - - - - - constraint - based theories of phonology have become enormously popular in recent years . such theories express generalizations by stating how and when a language 's phonological forms are constrained , rather than relying on rules that actively modify the forms . computational ideas have often provided an impetus for these innovations . koskenniemi 's ( 1983 ) 2 - level morphophonological processor introduced parallel constraining relations as an alternative to an ordered system of rewrite rules . declarative phonology ( c 1990 ) focusses on the unity of representations and rules as constraints , drawing on various computational ideas from unification to temporal logic to finite-state calculi . one current constraint-based theory is optimality theory ( ot ) ( prince&smolensky 1993 ) . this theory found , at least partial , inspiration in computational work by smolensky on the relation between symbolic and subsymbolic computation . although this link with connectionism has been left largely unexplored , ot has proved to be a computationally productive theory , giving rise to several theoretical papers on computational issues related to complexity and learnability , as well as inspiring a number of implementations . this workshop is designed to foster the link between computational work and constraint-based phonology in general . to this end , it invites submissions on topics related to the computation of any constraint-based phonological formalism , including but not limited to the three mentioned above . here are some example topics : * the computational interpretation of phonological theories , * constraint ranking and interaction , eg . as in ot , * implementations of particular analyses , * results in the complexity of constraint application , * algorithms for learning constraints or constraint ranking , * results on the learnability of such constraints , * novel formalisms for constraint-based phonology , * representational issues raised by constraint-based approaches . in short , papers are invited which address computational issues in constraint-based theories of phonology . submission -
