Knowledge Graph Suite for Reliable AI

Expert Rating

n/a

Overview

We propose the development of a domain-agnostic tooling suite, comprising KGTool and KG Studio, to automate the construction, processing, and interrogation of knowledge graphs (KGs) for scientific literature. By integrating large language models with graph-based reasoning, the system will support end-to-end workflows: from entity/relation extraction through graph refinement and fact-grounded generation to interactive visualization. This infrastructure will enable reliable, explainable AGI reasoning over diverse research corpora.

This RFP seeks the development of advanced tools and techniques for interfacing with, refining, and evaluating knowledge graphs that support reasoning in AGI systems. Projects may target any part of the graph lifecycle — from extraction to refinement to benchmarking — and should optionally support symbolic reasoning within the OpenCog Hyperon framework, including compatibility with the MeTTa language and MORK knowledge graph. Bids are expected to range from $10,000 - $200,000.

Proposal Description

Our Team

Our team combines over a decade of collaborative experience in machine learning, graph science, and full-stack development. Prior contributions include unsupervised learning tooling in MeTTa, GraphRAG integrations with Neo4j, and open-source agent frameworks.

Introduction


Knowledge graphs encode concepts as nodes and their interrelations as edges, forming a structured substrate for reasoning in LLM-powered applications [1]. However, assembling high-quality KGs from unstructured text remains challenging: errors in extraction, noisy or redundant connections, and LLM hallucinations hinder trustworthiness [2]. Our goal is to bridge these gaps by creating a unified framework that (a) constructs KGs automatically from scientific publications, (b) refines and analyzes graph structures, and (c) grounds LLM outputs through graph-based retrieval and reasoning.

Project Details

  • Technical Approach
    The system architecture comprises four components:

    1. KGTool: Core library offering graph construction, transformation, and query routines.

    2. KG Studio Backend: REST APIs exposing KGTool functionalities, orchestrating workflows for ingestion, analysis, and knowledge-grounded generation via the GraphRAG paradigm [3].

    3. KG Studio Front end: Web interface enabling non-technical users to upload documents, explore and manipulate KGs, and visualize reasoning paths.

    4. Graph Storage: Flexible backend (e.g., Hyperon) for persisting and indexing graph data.

  • LLMs will drive:

    1. Entity and relation extraction from scientific texts.

    2. GraphRAG: subgraph retrieval and augmentation of LLM responses with explicit graph citations.

  • Methodology

    1. Extraction

      • Identify concept nodes and typed edges via prompt-based LLM calls.

      • Allow optional specification of entity and relationship types for domain adaptation.

    2. Graph Refinement

      • Denoise: compute centrality and degree metrics to prune low-importance nodes.

      • Distill: apply spanning-tree algorithms to preserve core connectivity.

      • Cluster: detect communities and summarize clusters into higher-level concepts via LLMs.

    3. Conflict Resolution

      • Merge duplicate entities/relations and resolve logical inconsistencies (e.g., contradictory “IS” assertions) through rule-based and embedding-based alignment routines.

    4. Fact-Grounded Generation [3, 4, 5]

      • Embed graph contents to support retrieval-augmented queries.

      • Implement GraphRAG to match LLM-suggested subgraphs with stored KG facts, ensuring citations of source publications.

    5. Visualization & Interaction

      • Front-end dashboards for graph exploration, node/edge attribute inspection (including confidence scores), and stepwise control over workflows.

      • Visual explanations of reasoning chains, community structures, and grounding evidence.
