Error in Executing queries for LC-Quad #8

Open Reham-Osama opened 2 years ago

Reham-Osama commented 2 years ago

I tried to run the System on Qald 9 dataset as specified in the Read.me file, and it worked correctly. Then I tried to run it on Lc-Quad with the following parameters "-d lc-quad -uc true" but for all questions I am getting empty Golden Answer and Predicted Answer.

This can be seen in the following example for question 5:

[DEBUG] Golden sparql: SELECT DISTINCT ?uri WHERE { <http://dbpedia.org/resource/Joe_Pass http://dbpedia.org/ontology/associatedBand ?uri. http://dbpedia.org/resource/Dream_Dancing_(album) http://dbpedia.org/property/artist ?uri . } [INFO] SparqlGenerator list: [] [INFO] Golden Answer: [] [INFO] Predicted Answer: []

But in the log that you provide here it show non-empty Golden answer and Predicted answer lists as shown:

[DEBUG] Golden sparql: SELECT DISTINCT ?uri WHERE { http://dbpedia.org/resource/Joe_Pass http://dbpedia.org/ontology/associatedBand ?uri. http://dbpedia.org/resource/Dream_Dancing_(album) http://dbpedia.org/property/artist ?uri . } [INFO] SparqlGenerator list: [SELECT DISTINCT ?e0 WHERE { {?e0 http://dbpedia.org/ontology/associatedBand http://dbpedia.org/resource/Joe_Pass} UNION {http://dbpedia.org/resource/Joe_Pass http://dbpedia.org/ontology/associatedBand ?e0} . {?e0 http://dbpedia.org/property/artist http://dbpedia.org/resource/Dream_Dancing_(album)} UNION {http://dbpedia.org/resource/Dream_Dancing_(album) http://dbpedia.org/property/artist ?e0} . }, SELECT DISTINCT ?e0 WHERE { {?e0 http://dbpedia.org/ontology/associatedBand http://dbpedia.org/resource/Joe_Pass} UNION {http://dbpedia.org/resource/Joe_Pass http://dbpedia.org/ontology/associatedBand ?e0} . {?e0 http://dbpedia.org/ontology/artist http://dbpedia.org/resource/Dream_Dancing_(album)} UNION {http://dbpedia.org/resource/Dream_Dancing_(album) http://dbpedia.org/ontology/artist ?e0} . }] [INFO] Golden Answer: [http://dbpedia.org/resource/Ella_Fitzgerald] [INFO] Predicted Answer: [http://dbpedia.org/resource/Ella_Fitzgerald]

I ran the Golden SPARQL query against the Virtuoso endpoint to make sure that it is not the cause of the error, and it worked and returned the correct result, but during the running of the system, I get the explained output.

Would you please help me in solving this error?

It seems that the program failed to reach the virtuoso endpoint when running. Have you tried running the Golden SPARQL query through the runQuery method in KBUtil.java ?
