Hi I am interested in your datasets. May I ask why answers are not included in both train and test data? Thanks!

Thank you for looking in at our dataset.
We intentionally excluded the answer set in LC-QuAD 2.0 dataset for the following reason:

• Wikidata gets the updates regularly. So, the answer set we release today might be different in 6-months.
• In our perspective, the objective of the KGQA task is to find the correct formal query corresponding to a question. And one can easily evaluate any given query by simply executing it on Wikidata SPARQL endpoint (https://query.wikidata.org)

Please let us know if you have further queries or suggestion.
