TeBaQA is available at https://tebaqa.demos.dice-research.org/
TeBaQA implements microservices architecture. The application comprises following 5 modules:
- Template Classification :- to classify query templates (localhost:8081)
- Entity Linking :- finding and linking entities and relations (localhost:8082)
- Query Ranking :- candidate query execution, ranking (localhost:8083)
- TeBaQA Controller :- central controller, frontend application (localhost:8080)
- NLP Server :- CoreNLP Server endpoint (localhost:8085)
Additionally, Entity Linking requires Elasticsearch indices for data and ontology of the knowledge base. Check this file for more information on creating your own indices.

- To answer a question, simply execute an HTTP POST request to
http://localhost:8080/qa
for the answer which follows the W3C Query Results JSON Format (see https://www.w3.org/TR/sparql11-results-json/).http://localhost:8080/qa-simple
for a simple JSON with only the answer.
- Parameters:
query
: A string which contains a question (required).lang
: The language of the question (default:en
) Note: Other languages than English haven't been implemented yet.
- An example request could look like this:
http://localhost:8181/qa?query=What is the original title of the interpretation of dreams?&lang=en
