It's not Haskell-specific, but you should look at the work done by
Xerox on XFST/OpenFST. One of the major issues they needed to tackle
is how to avoid the exponential blowup that can arise from
manipulating FSTs. I don't recall how much simplification they do, but
their main goal and use case was also dealing with natural language.
