Official Implementation of "Reasoning on Graphs: Faithful and Interpretable Large Language Model Reasoning".
Reasoning on graphs (RoG) synergizes LLMs with KGs to enable faithful and interpretable reasoning. We present a planning-retrieval-reasoning framework, where RoG first generates relation paths grounded by KGs as faithful plans. These plans are then used to retrieve valid reasoning paths from the KGs for LLMs to conduct faithful reasoning and generate interpretable results.

You can find the pre-trained weights here.
Subgraph Extraction
We extract the subgraphs from the Freebase following previous studies. The code can be found here.
Requirements: Any GPU with at least 12GB memory.
