Can't use eds.loads to obtain a EDS from the result of eds.dumps

[Aria-K-Alethia]

Hi,

I use HTTP request to parse a sentence to EDS. And I use eds.dumps() to dump it to raw string. But when I use eds.loads() to recover it, I found no output result.

Below is my code:

 >>>text = Successful American business owners do the same thing.
 >>>res = rest.parse(exs[1].text, params={'eds':'json'})
 >>>res = res.result(0).eds()
 >>>raw = eds.dumps(res, properties = 1, single = 1)
 >>>raw
'{e3:\n _1:udef_q<0:35>[BV x6]\n e9:_successful_a_1<0:10>{e MOOD indicative, PERF -, PROG -, SF prop, TENSE untensed}[ARG1 x6]\n e10:_american_a_1<11:19>{e MOOD indicative, PERF -, PROG -, SF prop, TENSE untensed}[ARG1 x6]\n e12:compound<20:35>{e MOOD indicative, PERF -, PROG -, SF prop, TENSE untensed}[ARG1 x6, ARG2 x11]\n _2:udef_q<20:28>[BV x11]\n x11:_business_n_1<20:28>{x }[]\n x6:_owner_n_of<29:35>{x IND +, NUM pl, PERS 3}[]\n e3:_do_v_1<36:38>{e MOOD indicative, PERF -, PROG -, SF prop, TENSE pres}[ARG1 x6, ARG2 x18]\n _3:_the_q<39:42>[BV x18]\n e23:_same_a_as<43:47>{e MOOD indicative, PERF -, PROG -, SF prop, TENSE untensed}[ARG1 x18]\n e25:comp_equal<43:47>{e MOOD indicative, PERF -, PROG -, SF prop, TENSE untensed}[ARG1 e23]\n x18:_thing_n_of-about<48:54>{x IND +, NUM sg, PERS 3}[]\n}'
>>>list(eds.loads(raw))
[]

Why?

There are a number of issues with the code as posted, but I'll assume those were just accidentally made when posting the issue. I can reproduce the problem with the following MWE:

>>> from delphin.mrs import eds
>>> from delphin.interfaces import rest
>>> text = 'Successful American business owners do the same thing.'
>>> res = rest.parse(text, params={'eds':'json'})
>>> x = res.result(0).eds()
>>> raw = eds.dumps(x, properties=True, single=True)
>>> list(eds.loads(raw))
[]

I suspect that the EDS parser is failing to parse the raw representation and giving up (the empty list just means that no EDS representations were found in the input string, but clearly that's not the case here). Perhaps due to the empty property list on _business_n_1 or maybe the hyphen in the predicate name in _thing_n_of-about, neither of which are invalid. I'll take a look.

In the meantime, what is it you want to accomplish? It seems the JSON parser of EDS is working fine, so you could work with that representation, or maybe the PENMAN one, if it's easier?

Thank you for your help.

What I need here is a EDS parser for raw text representation, since I have many such kind of things(from deepbank). However, before parsing them I found this problem.
