I am reviewing the Ling567 lab instructions in order to see if I can borrow something for the Grammar Matrix implementation of constituent questions.
The first question that I have is: what is the purpose of this? The instructions don’t explain.
basic-head-filler-phrase :+ [ ARGS & < [ SYNSEM.LOCAL.COORD - ], [ SYNSEM.LOCAL.COORD - ] > ].
The only other place the COORD feature appears is in the instructions for Y/N questions:
Constrain the root symbol to require an empty YNQ value: root := phrase & [ SYNSEM [ LOCAL [ COORD -, CAT [ VAL [ SUBJ < >, COMPS < > ], MC +, HEAD +vc & [ FORM finite ] ] ], NON-LOCAL.YNQ 0-dlist ] ].
– But I don’t think it is referred to directly anywhere.
From the comments in matrix.tdl I can see that [ COORD - ] means the phrase is not participating in coordination. But what will be the specific consequences of changing the filler phrase definition like that? I suspect that for the GM, I don’t want this, but I don’t really understand yet.
