Amazon Web Services (AWS) introduced Knowledge Bases for Amazon Bedrock in November 2023, enabling secure Retrieval Augmented Generation (RAG) for machine learning models. RAG allows companies to connect their private data to AI models, improving response relevance without exposing sensitive information. NordHero developed a demo using ReactJS and AWS services to showcase RAG capabilities. The demo features a chat interface where users can ask questions about documents in a knowledge base, which contains the Finnish IT Service Industry Collective Agreement. The AI generates responses in both Finnish and English, regardless of the document language. The architecture uses various AWS services, including API Gateway, Lambda, Amazon Bedrock, S3, and OpenSearch. This technology has potential applications in internal document searching and automated customer service chatbots, offering a secure way to leverage AI with private data.
