Closed goodmami closed 3 years ago

goodmami commented 4 years ago

Item 291 in the mrs test suite gives the following bad MRS in the 2018 version and trunk:

[ "Abrams wondered which dog barked."
  TOP: h0
  INDEX: e2 [ e SF: prop TENSE: past MOOD: indicative PROG: - PERF: - ]
  RELS: < [ proper_q<0:6> LBL: h4 ARG0: x3 [ x PERS: 3 NUM: sg IND: + ] RSTR: h5 BODY: h6 ]
          [ named<0:6> LBL: h7 ARG0: x3 CARG: "Abrams" ]
          [ relative_mod<7:33> LBL: h1 ARG0: i9 ARG1: x10 [ x PERS: 3 NUM: sg IND: + ] ARG2: h11 ]
          [ udef_q<7:33> LBL: h12 ARG0: x10 RSTR: h13 BODY: h14 ]
          [ generic_entity<7:33> LBL: h15 ARG0: x10 ]
          [ _wonder_v_1<7:15> LBL: h1 ARG0: e2 ARG1: x3 ]
          [ _which_q<16:21> LBL: h16 ARG0: x10 RSTR: h17 BODY: h18 ]
          [ _dog_n_1<22:25> LBL: h19 ARG0: x10 ]
          [ _bark_v_1<26:33> LBL: h11 ARG0: e20 [ e SF: prop TENSE: past MOOD: indicative PROG: - PERF: - ] ARG1: x10 ] >
  HCONS: < h0 qeq h1 h5 qeq h7 h13 qeq h15 h17 qeq h19 > ]

Note that udef_q, generic_entity, _which_q, and _dog_n_1 all share the ARG0 of x10.

This analysis is not present in the 1214 version, so it appears to be a regression.

The bad MRS came from an unwanted parse, which the ERG now excludes.
