Multi-hops for SQARQL in knowledge graph

[SamYuen101234]

Hello, I have tried your pre- trained model BART on the harry potter knowledgde graph. The examples you provided are single hop only, any ability for the pre-trained model to translate human questions into SPARQL queries for multi-hop questions？ Or I need to define my own datasets for multi-hop questions？ Thank you.

Hey @SamYuen101234, to use knowledge graphs with your dataset, you need to train your model for sure. We have a guide on how to do that: Trying Question Answering on Knowledge Graphs with Custom Data. As you train a new model, you can try to formulate your data in a way that it supports multi-hop questions and check if it works.
You can report the bugs as you go, but please remember that knowledge graphs are a low priority for Haystack.
