The Evolution of RAG

Moving beyond binary relations (triplets) to model complex n-ary facts. Integration of HRKG allows LLMs to reason over multi-dimensional data like conditions, dosages, and protocols simultaneously via a single hyperedge.

Hyperedges

Connect 3+ entities concurrently, capturing higher-order semantic links without context loss.

Qualifiers

Detailed attributes (temp, cell line, conc) that provide specific grounding to relationships.

The Bottleneck Challenge

01

Semantic Fragmentation

Flattening n-ary facts into binary triples destroys the holistic context, leading to retrieval of incomplete or misleading info.

02

Path Explosion

Reasoning over multi-hop queries in binary graphs causes exponential noise and computational drain.

03

Reasoning Failure

Standard LLMs hallucinate logical links when retrieved contexts lack explicit qualifiers or structures.

Research Questions

  • 1

    Automating lossless extraction from unstructured text using TxGemma.

  • 2

    Balancing topology with semantic vector similarity for n-ary retrieval.

  • 3

    Modeling "trajectories" to enhance sequential process reasoning.

Industry Applications

Pharma & Bio

AssayKG-RAG

Query novel scaffold hits while maintaining strict provenance over assay protocols, target thresholds, and cell line contexts.

Healthcare

Precision Medicine

Reasoning over multi-condition medical facts like demographics, serum levels, and diagnostic criteria for clinical support.

Regulatory

Legal Compliance

Managing complex "if-then" logic across jurisdictions, temporal constraints, and multi-entity regulatory frameworks.

Local Implementation Idea

Optimized for MacBook Pro M3/M4 Local Environments

1

Hypergraph Construction

Use RDKit + LLMs (TxGemma/Gemma 4) with ICL few-shot prompting to extract n-ary relations from PubMed and ChEMBL.

2

Dual-Embedding Retrieval

Employ hybrid indexing (NetworkX + FAISS) for structural and semantic lookup with diffusion-based refinement.

3

Provenance-Aware ICL

Structure prompts as: "Given hyperedges: [list]... Answer with qualifiers." to ensure grounding.

Open Problems

  • Temporal Scaling: Representing shifting facts without redundancy.
  • Hybrid Indexing: Low-latency billion-scale hyperedge indexing on edge devices.
  • Fine-Grained Auditability: Direct audit trails for every qualifier used in reasoning.

Future Directions

  • Causal Hypergraph RAG: Counterfactual reasoning (e.g., dosage modification effects).
  • Autonomous Agents: HRKG-driven hypothesis generation for experiments.
  • Localized Therapeutics: High-trust, auditable clinical AI on local systems.
