Parallel Replacement in Finite State Calculus
Andre Kempe, Lauri Karttunen
This paper extends the calculus of regular expressions with new types of replacement expressions that
enhance the expressiveness of the simple replace operator defined in Karttunen (1995). Parallel replacement
allows multiple replacements to apply simultaneously to the same input without interfering with each other.
We also allow a replacement to be constrained by any number of alternative contexts. With these
enhancements, the general replacement expressions are more versatile than two-level rules for the description
of complex morphological alternations.
