[developers] pyDelphin and JACY

[Tuấn Anh Lê]

Hi everyone,

I found this bug while using pyDelphin to process MRS output from JACY. Can
someone shed some light on this for me?

The original sentence was "猫を見ていた。"

Source code
---------------------------------------
import io
from delphin.mrs import simplemrs
from delphin.mrs import dmrx

m = '''[ TOP: h0
  INDEX: e2 [ e TENSE: past MOOD: indicative PROG: - PERF: - ASPECT:
default_aspect PASS: - SF: prop ]
  RELS: < [ udef_q_rel<0:1> LBL: h4 ARG0: x5 [ x PERS: 3 ] RSTR: h6 BODY:

          [ "_neko_n_rel"<0:1> LBL: h8 ARG0: x5 ]
          [ "_miru_v_1_rel"<4:5> LBL: h9 ARG0: e10 [ e TENSE: tense MOOD:

  HCONS: < h0 qeq h1 h6 qeq h8 h13 qeq h9 h14 qeq h15 > ]'''

# MRS string to pyDelphin
obj = simplemrs.loads_one(m)
print(obj)

# pyDelphin to XML
x = dmrx.etree_tostring(dmrx._encode_dmrs(obj)).decode('utf-8')
print(x)

# XML back to pyDelphin
dmrses = list(dmrx.deserialize(io.StringIO(x)))
print(dmrses)
