To be precise, Kimmo Koskoniemmi devised the theory behind PC-Kimmo. Evan Antworth of SIL developed the PC-Kimmo program.

The theory of phonology implemented by PC-Kimmo is not the standard ordered rule model that they taught when I learned phonology (typical generative phonology) -- but it's computationally tractable enough (in practice). I use the kgen program to write symbolic rules, as hand-compiling FSA tables is not my idea of fun! It's a bit buggy, however, and won't handle some kinds of expression that you would expect that it could (for instance, the same symbol set can only have on repetition specification in a given rule). This makes patterns like C*VC* tricky, depending on what you want it to do. Xerox has some lexical compilation technology based on the same theoretical model as PC-KIMMO, (Koskonienni works there now) and they used to offer a web-based compilation service that produced PC-KIMMO driver files. Their pages are at -- worth checking out, as there's lots of info. I don't think that there's a publicly available version of the tools (without paying big bucks, anyway). -- David _________________________________________ David Durand \ Boston University Computer Science \ Sr. Analyst \ Dynamic Diagrams --------------------------------------------\ MAPA: mapping for the WWW \__________________________
