Summary

A solution leveraging Bring Your Own Knowledge Graph (BYOKG) and Graph-based Retrieval Augmented Generation (GraphRAG) is transforming pharmaceutical research by unifying fragmented scientific data. This approach, built on Amazon Neptune Analytics and Amazon Bedrock, integrates diverse entities like compounds, genes, and health effects from sources such as PubMed and Gene Ontology into a single knowledge graph. It enables researchers to ask complex natural language questions and receive instant, evidence-backed insights with detailed citation paths. The system, which uses Amazon Comprehend Medical for ICD-10-CM linking and the "graphrag-toolkit" with the Anthropic Claude 4.5 Sonnet model, claims to reduce research cycles from six months to three weeks, an 87% efficiency boost, and improve discovery success rates. This enhances transparency and reproducibility in scientific discovery.

Key takeaway

For research scientists struggling with fragmented data and slow discovery, adopting a GraphRAG solution built on Amazon Neptune Analytics and Amazon Bedrock can drastically accelerate your work. You can reduce research cycles by 87%, from six months to three weeks, and enhance discovery success rates. Implement this by integrating your diverse data into a unified knowledge graph, enabling natural language queries for evidence-backed insights. This approach ensures transparency and reproducibility, critical for regulatory compliance and scientific rigor.

Key insights

GraphRAG with BYOKG unifies fragmented scientific data into a knowledge graph, accelerating pharmaceutical discovery with evidence-backed, natural language insights.

Principles

• Unify disparate data into a knowledge graph.
• Augment generative AI with graph traversal.
• Preserve institutional memory via structured data.

Method

Build a BYOKG using Amazon Neptune Analytics, ingest diverse data via automated pipelines, then implement GraphRAG with Amazon Bedrock and "graphrag-toolkit" for natural language querying and entity linking.

In practice

• Integrate PubMed, Gene Ontology, proprietary data.
• Use "graphrag-toolkit" for RAG implementation.
• Query complex relationships in natural language.
