Challenges and future directions in graph-based RAG
Let’s consider some key challenges and future research directions in graph-based RAG:
- Scalability to very large graphs
- Handling dynamic and evolving graph structures
- Incorporating uncertainty and probabilistic relationships
- Improving the interpretability of graph-based retrievals and generations
- Developing more sophisticated graph-aware language models
These are fascinating and complex research topics. In this chapter, we’ll focus on the scalability aspect of graph-based RAG. You are encouraged to read the research paper titled Graph Retrieval-Augmented Generation: A Survey at https://arxiv.org/abs/2408.08921 for more information on other challenges and research directions.
Real-world knowledge graphs can contain millions or even billions of nodes and edges. Querying and traversing such massive graphs can be computationally expensive, especially when incorporated into a real-time RAG...
