Here is why: PC-Kimmo was good for two things: - Even Antworth wrote a nice (and still valid) intro to twol-c (two-level morphology) - PC-Kimmo was nice in the days __before__ we had compilers for the twol rules. Now we have compilers for the twol rules, be it the xerox tools like twolc (http://fsmbook.com) or hfst (and there is sfst, with another rule syntax). So, we linguists should do what we can: Write morphophonological rules (in twolc and hfst-twolc), and let the compilers compile. The alternative is to write finite state tables for the automata, as explained in Antworth's book. Trust me, I did linguistics in the 80ies, and actually got some tables working. If you want to see the tables, you may use the option show-rules in twolc, and then be glad you did not have to write what you see there. >> >> It is amazing, I dont know if HFST can do a tokenization and parsing >> like that? > Yes it can, and much more. You may write your rules (the same rules) in PC-Kimmo or in HFST or Xerox's twolc. The difference is that only the latter two have compilers that make you able to run the rules.
