Regulus for DORIS

When I was visiting Melbourne Uni last week, I talked with Patrick Ye about the possibility of using Regulus to provide speech recognition for the DORIS project, which, as he pointed out, is in fact quite similar to SHRD2; in both domains, the basic idea is to find things, pick them up, and move them around. I did indeed find it very easy to use the examples corpus and vocabulary that Patrick sent me to adapt the existing SHRD2 resources, and in just a few hours put together an initial Regulus grammar that could be compiled into a recogniser. The current version of the grammar covers a bit more than 80% of Patrick's corpus, and the recogniser can turn spoken sentences in Australian-accented English into either strings of words or scoped logical forms. For example, here's the representation it produces of "the red book is on the desk":

[[dcl,
  quant(def_sing, A, [[book,A],[color,A,red]],
        quant(def_sing, B,
              [[desk,B]],
              quant(exist,C,[[be_on_loc,C,A,B],[tense,C,present]],true)))]]

If people want to look at the details, the files are checked in at http://regulus.cvs.sourceforge.net/viewvc/regulus/Regulus/Examples/Doris/. The interesting ones are the lexicon, at http://regulus.cvs.sourceforge.net/viewvc/regulus/Regulus/Examples/Doris/Regulus/doris_lex.regulus, and the corpus, at http://regulus.cvs.sourceforge.net/viewvc/regulus/Regulus/Examples/Doris/corpora/doris_corpus.pl
