I am using concept parser (senticnet) to extract the concepts from text. I am using PYcharm platform. Can anybody please guide how the following error can be removed. According to analysis i found that the format of parse tree (nlp.parse(sentence)) is not compatible with json dictionary format. Can anybody pleeeeeeease help me in this regard.
File "C:\Python27\Lib\json\__init__.py", line 339, in loads
return _default_decoder.decode(s)
File "C:\Python27\Lib\json\decoder.py", line 366, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "C:\Python27\Lib\json\decoder.py", line 384, in raw_decode
raise ValueError("No JSON object could be decoded")
ValueError: No JSON object could be decoded
@Behzad Rouhanizadeh
Can you provide a minimal example of your code that produce the error?
Sir,
nlp = StanfordCoreNLP(r'C:\Users\Maryum\Downloads\stanford-corenlp-full-2018-02-27\stanford-corenlp-full-2018-02-27')
mystr= nlp.parse(senten)// In this statement the english language senetence has been parsed into parse tree as shown below:
(ROOT
(S
(NP
(NP (NNP Takahama) (POS 's))
(JJ problematic))
(VP (VBP restart)
(NP
(NP (NN https://t.co/3hx12xWrnf) (NN #G7summit) (NN #summit) (NN #G7) (NN #Hiroshima) (NN #fukushima) (NN #NoNukes))
(NP (JJ #nuclear) (NN #Nagasaki) (NN #Japan))))))
But When this parse tree is loaded into json Dictionary format using following instruction
myDict = json.loads(mystr)
The error generates that
File "C:/Users/Maryum/Downloads/concept-parser-master/concept-parser-master/stanford-corenlp-python-final/concept_parser.py", line 622, in main
myDict = json.loads(mystr)
File "C:\Python27\Lib\json\__init__.py", line 339, in loads
return _default_decoder.decode(s)
File "C:\Python27\Lib\json\decoder.py", line 366, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())
File "C:\Python27\Lib\json\decoder.py", line 384, in raw_decode
raise ValueError("No JSON object could be decoded")
ValueError: No JSON object could be decoded
Please see the code for the python class StanfordCoreNLP and especially the comment block for the parse method (https://github.com/SenticNet/concept-parser/blob/master/stanford-corenlp-python-final/corenlp.py):
The output from mystr= nlp.parse should be a serialized JSON string. Have you tried add a print(mystr) after parse? What is the output?
I suspect there may be non unicode characters in your string (see specification in https://docs.python.org/2/library/json.html for dumps and loads). Make sure your scripts are saved in unicode. If that does not work, please post the actual output from print(mystr) after nlp.parse.
