Amazon Bedrock Knowledge Bases is the correct approach for this use case. Here's why:

• Knowledge Bases allow you to connect foundation models to your company's data sources, including S3 buckets
• They can ingest documents from S3 and create vector embeddings for retrieval-augmented generation (RAG)
• This enables the chatbot to combine general AI knowledge with specific information from the university's internal research papers
• The chatbot can then provide responses that are grounded in both the foundation model's general knowledge and the specific research content

Other options:

• Agents: Used for multi-step tasks and tool use, not specifically for connecting to knowledge sources
• Guardrails: Focus on safety and content filtering
• Model evaluation: Used for testing and comparing model performance

Knowledge Bases is specifically designed for the scenario described - augmenting foundation models with custom data sources like S3-stored documents.
