We do have a knowledge graph index. You can manually insert existing triplets (rather than the default of letting the LLM extract them), but each triplet also needs a node that has the text where that triplet came from
Although you could work around this by passing in dummy nodes, and then using include_text=False when querying
Thanks @Logan M! Our company also has its own strucutral causal models (SCMs) in DAG of variety of causal variables and mechanism (a functional relationship) between them - is there any way that I can use those SCMs to inject them as a context using llama-index?
