Empty response

[YaserJaradeh]

I have followed the instructions to run SQG with all the dependencies (with all the noted versions) and it seems to run smoothly and without any problem.

I am trying to run the example call you have provided in the README file but the response is returned as {}. I have played around with the query and tried

{
   "question":"What is the birth place of Barack Obama?",
   "relations":[
      {
         "surface":"",
         "uris":[
            {
               "confidence":1,
               "uri":"http://dbpedia.org/ontology/birthPlace"
            }
         ]
      }
   ],
   "entities":[
      {
         "surface":"",
         "uris":[
            {
               "confidence":1,
               "uri":"http://dbpedia.org/resource/Barack_Obama"
            }
         ]
      }
   ],
   "kb":"dbpedia"
}

and another query:

{
   "question":"Who is the wife of Barack Obama?",
   "relations":[
      {
         "surface":"",
         "uris":[
            {
               "confidence":1,
               "uri":"http://dbpedia.org/ontology/spouse"
            }
         ]
      }
   ],
   "entities":[
      {
         "surface":"",
         "uris":[
            {
               "confidence":1,
               "uri":"http://dbpedia.org/resource/Barack_Obama"
            }
         ]
      }
   ],
   "kb":"dbpedia"
}

I always get the same response (am empty set of queries):

{}

I have checked the errors.log and the info.log files and there is nothing out of the ordinary going on there, plus I am checking the python console for any errors/warnings and there is nothing to see also.
I am running the code on Ubuntu 18.04.1 LTS Desktop with Intel(R) Xeon(R) W-2133 CPU and 64GB of Ram.

If you could point me in the direction of what might be the cause of the problem or something like this?

I have the same behavior. It seems to start correctly, but I don't get any response

`$ curl -i -H "Content-Type: application/json" -X POST -d '{"question":"What is the hometown of Nader Guirat, where Josef Johansson was born too?","relations":[{"surface":"","uris":[{"confidence":1,"uri":"http://dbpedia.org/property/birthPlace"}]},{"surface":"","uris":[{"confidence":1,"uri":"http://dbpedia.org/ontology/hometown"}]}],"entities":[{"surface":"","uris":[{"confidence":0.7,"uri":"http://dbpedia.org/resource/Josef_Johansson"},{"confidence":0.3,"uri":"http://dbpedia.org/resource/Barack_Obama"}]},{"surface":"","uris":[{"confidence":1,"uri":"http://dbpedia.org/resource/Nader_Guirat"}]}],"kb":"dbpedia"}' http://localhost:5000/qg/api/v1.0/query

And the logs on the server seem to be correct:
