This directory contains samples for a QA chain using an AmazonKendraRetriever class. For more info see the samples README. Note: If you are using an older version of the repo which contains the aws_langchain package, please clone this repo in a new location to avoid any conflicts with the older environment. We are deprecating the aws_langchain package, since the kendra retriever class is available in LangChain starting v0.0.213.

For detials of the implementation please refer to blog : https://aws.amazon.com/blogs/machine-learning/quickly-build-high-accuracy-generative-ai-applications-on-enterprise-data-using-amazon-kendra-langchain-and-large-language-models/
