QADO SPARQL Query Analyser

This service provides a Web API to process the SPARQL queries of the QADO dataset and enriches them with additional properties. It contains 2 components:

• SPARQL Query Analyser Web API: Web API for starting SPARQL query analyses
• SPARQL Analyser: asynchronous execution of analysis tasks

Usage

The service is available as a pre-build Docker Image and can be run by executing the following commands:

docker pull wseresearch/sparql-analyser-api:latest
docker run -itd -v /var/run/docker.sock:/var/run/docker.sock -p 8080:80 wseresearch/sparql-analyser-api:latest

The API description is available at http://localhost:8080/swagger/index.html. For using the service a triplestore with the QADO dataset is required. Currently, Stardog and GraphDB are supported.
