For Llamaindex Knowledge Graph Extractors (SimpleLLMPathExtractor), as I understand, each chunk text will be fetched into the LLM model to extract triplets. Then, will this LLM extractions of each chunk be independent from each other, or how do they know information regarding previous LLM calls (eg: how do they know about the other chunks and triplets from them)? If the calls are independent, then how does LlamaIndex ensure that there are no duplicate nodes / relationships in the knowledge graph, and how to deal with some information that is across chunks?
