OnSET

Live Demo

In progress...

Description

OnSET should enable a more explorative ontology querying experience for non-expert users, and to build a quick understanding of the scale and nature of a KG that is in use.

Setup instruction

1. Download object and instances form DBPEDIA: DBPEDIA-Data: ontologies, this may take some time!
2. Setup a local qlever instance (https://github.com/ad-freiburg/qlever-control) (the used configurations can be found in docker/bto-data and docker/dbpedia-data)
3. Start auxiliary DB using cd docker/onset-data && docker-compose up -d
4. Backend setup:
   • install uv (https://docs.astral.sh/uv/getting-started/installation/)
   • install dependencies using uv sync
   • start backend (should initialize DB on first start) using the correct Python installation using python -m uvicorn api:app --reload --port 8001
5. Frontend setup:
   • install a somewhat recent Node version
   • install dependencies by first cd frontend && npm i -D
   • then start the frontend using npm run dev

• Profit?
