	## Dataset Structure

	We show detailed information for up to 5 configurations of the dataset.

	### Data Instances

	#### default

	- Size of downloaded dataset files: 3.69 MB
	- Size of the generated dataset: 19.77 MB
	- Total amount of disk used: 23.46 MB

	An example of 'train' looks as follows.
	```
	This example was too long and was cropped:

	{
	"NNQT_question": "What is the {periodical literature} for {mouthpiece} of {Delta Air Lines}",
	"paraphrased_question": "What is Delta Air Line's periodical literature mouthpiece?",
	"question": "What periodical literature does Delta Air Lines use as a moutpiece?",
	"sparql_dbpedia18": "\"select distinct ?obj where { ?statement <http://www.w3.org/1999/02/22-rdf-syntax-ns#subject> <http://wikidata.dbpedia.org/resou...",
	"sparql_wikidata": " select distinct ?obj where { wd:Q188920 wdt:P2813 ?obj . ?obj wdt:P31 wd:Q1002697 } ",
	"subgraph": "simple question right",
	"template": " <S P ?O ; ?O instanceOf Type>",
	"template_index": 65,
	"uid": 19719
	}
	```

	### Data Fields

	The data fields are the same among all splits.

	#### default
	- `NNQT_question`: a `string` feature.
	- `uid`: a `int32` feature.
	- `subgraph`: a `string` feature.
	- `template_index`: a `int32` feature.
	- `question`: a `string` feature.
	- `sparql_wikidata`: a `string` feature.
	- `sparql_dbpedia18`: a `string` feature.
	- `template`: a `string` feature.
	- `paraphrased_question`: a `string` feature.
