I’m having issues with generating compound nouns with the ERG. I’m trying to generate “trash can,” but if I don’t specify number information I get stuff like “trashes can.” I tried to enforce the fact that the ARG0 of “trash” should be singular, but it won’t generate from an MRS with that information (ARG2 of compound shows the information, but I assume anywhere where x2 is found has that information too):
[ TOP: h19 INDEX: e16 RELS: < [ unknown LBL: h18 ARG: x12 ARG0: e16 ] [ _the_q LBL: h15 ARG0: x12 RSTR: h13 BODY: h14 ] [ compound LBL: h11 ARG0: e8 ARG1: x12 ARG2: x2 [ x NUM: sg ] ] [ udef_q LBL: h7 ARG0: x2 RSTR: h5 BODY: h6 ] [ _trash_n_1 LBL: h3 ARG0: x2 ] [ _can_n_1 LBL: h11 ARG0: x12 ] > HCONS: < h5 qeq h3 h13 qeq h11 h19 qeq h18 > ]
When I parse “the trash can” with the ERG I get an MRS like this:
[ LTOP: h0 INDEX: e2 [ e SF: prop ] RELS: < [ unknown<0:13> LBL: h1 ARG0: e2 ARG: x4 [ x PERS: 3 NUM: sg IND: + ] ] [ _the_q<0:3> LBL: h5 ARG0: x4 RSTR: h6 BODY: h7 ] [ compound<4:13> LBL: h8 ARG0: e9 [ e SF: prop TENSE: untensed MOOD: indicative PROG: - PERF: - ] ARG1: x4 ARG2: x10 ] [ udef_q<4:9> LBL: h11 ARG0: x10 RSTR: h12 BODY: h13 ] [ _trash_n_1<4:9> LBL: h14 ARG0: x10 ] [ _can_n_1<10:13> LBL: h8 ARG0: x4 ] > HCONS: < h0 qeq h1 h6 qeq h8 h12 qeq h14 > ICONS: < > ]
It seems to not record the fact that x10 is singular, but if I don’t enforce that on the generation side I end up with “trashes” can, so I’m not sure what’s going on.
Any help would be greatly appreciated!
