John Chen implemented one a couple of years ago. He has a paper in some conf,
probably on his website as well. Recently, John, Srini and Mike Collins have
used re-ranking to improve on an existing supertagger (either John's or a
newly implemented one) -- the results were reported in TAG+ in Venice.
More recently, Libin Shen (2nd year student of Joshi's) has new numbers on
supertagging that beat previous results. His email is libin@linc.
> -Has there been any attempt to do rule-based supertagging ?
I think Srini tried to use Transformation Based Learning for supertagging. It
was infeasible with the existing Brill implementation due to memory and time
overruns as far as I can remember. I think he probably has a line in this
thesis saying this.
