Feature Request: Add Function extract_graph_nlp

[YiboZhao624]

Hi contributors:

As the Microsoft GraphRAG was updated to v2.1.0, some new important features were added, including extract_graph_nlp, which uses the NLP tools instead of LLM intelligence to extract the nodes and weighted edges based on the co-occurrence. I think it is an important feature to alleviate the high cost during the indexing stage. Therefore, I am here to ask if it is in the development plan? If not, I will try my best to integrate this feature into this repo.

Best, Yibo Zhao.

Hi @YiboZhao624. Using rules to crawl graphs plays a significant role in lowering user costs (even if there might be some performance considerations), and that's a really interesting feature. We're excited for everyone to participate in building this project, so why not give it a try right now? 😄
