Online Demo (API)

The API is available at https://wse-research.org/api/sparql2nl

Sample SPARQL2NL API request:

curl -X 'GET' \
  'https://wse-research.org/api/sparql2nl?query_text=QUERYTEXT&language=LANG&shots=SHOTS&model=MODELID' \
  -H 'accept: application/json'

• query_text: a SPARQL query over Wikidata or DBpedia

• language: English (en), German (de), or Russian (ru)

• shots: zero-shot (0), one-shot (1)

• model: model id (any text model from OpenAI https://platform.openai.com/docs/models)

Feedback API request:

curl -X 'POST'  'https://wse-research.org/api/sparql2nl-feedback' \
  -H 'accept: application/json' \
  -H 'Content-Type: application/json' \
  -d '{
"query_text": "SELECT * WHERE { ?s ?p ?o }",
"verbalization": "select everything",
"rating": 5,
"comment": "cool"
}'

• query_text: a SPARQL query over Wikidata or DBpedia

• verbalization: a result of our model

• rating: a grade from 1 (bad) to 5 (good)

• comment: optional, additional notes to the result
