Intelligent Scientific Reasoning through Graph-of-Thoughts

🚀 Next-Generation AI Reasoning Framework for Scientific Research Leveraging graph structures to transform how AI systems approach scientific reasoning

🔍 Overview

NexusMind leverages graph structures to perform sophisticated scientific reasoning. It implements the Model Context Protocol (MCP) to integrate with AI applications like Claude Desktop, providing an Advanced Scientific Reasoning Graph-of-Thoughts (ASR-GoT) framework designed for complex research tasks.

Key highlights:

• Process complex scientific queries using graph-based reasoning
• Dynamic confidence scoring with multi-dimensional evaluations
• Built with modern Python and FastAPI for high performance
• Dockerized for easy deployment
• Modular design for extensibility and customization
• Integration with Claude Desktop via MCP protocol

The core reasoning process follows a sophisticated 8-stage pipeline:

1. 🌱 Initialization

   • Creates root node from query with multi-dimensional confidence vector
   • Establishes initial graph structure with proper metadata
   • Sets baseline confidence across empirical, theoretical, methodological, and consensus dimensions

2. 🧩 Decomposition

   • Breaks query into key dimensions: Scope, Objectives, Constraints, Data Needs, Use Cases
   • Identifies potential biases and knowledge gaps from the outset
   • Creates dimensional nodes with initial confidence assessments

3. 🔬 Hypothesis/Planning

   • Generates 3-5 hypotheses per dimension with explicit falsification criteria
   • Creates detailed execution plans for each hypothesis
   • Tags with disciplinary provenance and impact estimates

4. 📊 Evidence Integration

   • Iteratively selects hypotheses based on confidence-to-cost ratio and impact
   • Gathers and links evidence using typed edges (causal, temporal, correlative)
   • Updates confidence vectors using Bayesian methods with statistical power assessment

5. ✂️ Pruning/Merging

   • Removes nodes with low confidence and impact scores
   • Consolidates semantically similar nodes
   • Optimizes graph structure while preserving critical relationships

6. 🔍 Subgraph Extraction

   • Identifies high-value subgraphs based on multiple criteria
   • Focuses on nodes with high confidence and impact scores
   • Extracts patterns relevant to the original query

7. 📝 Composition

   • Synthesizes findings into coherent narrative
   • Annotates claims with node IDs and edge types
   • Provides comprehensive answers with proper citations

8. 🤔 Reflection

   • Performs comprehensive quality audit
   • Evaluates coverage, bias detection, and methodological rigor
   • Provides final confidence assessment and improvement recommendations

🚀 Getting Started

Prerequisites

• Python 3.13+ (Docker image uses Python 3.13.3-slim-bookworm)
• Poetry: For dependency management
• Docker and Docker Compose: For containerized deployment

Installation and Setup (Local Development)

1. Clone the repository:

   git clone https://github.com/SaptaDey/NexusMind.git
   cd NexusMind

2. Install dependencies using Poetry:

   poetry install

   This creates a virtual environment and installs all necessary packages specified in pyproject.toml.

3. Activate the virtual environment:

   poetry shell

4. Configure the application:

   # Copy example configuration
   cp config/settings.example.yaml config/settings.yaml
   
   # Edit configuration as needed
   vim config/settings.yaml

5. Set up environment variables (optional):

   # Create .env file for sensitive configuration
   echo "LOG_LEVEL=DEBUG" > .env
   echo "API_HOST=0.0.0.0" >> .env
   echo "API_PORT=8000" >> .env

6. Run the development server:

   python src/asr_got_reimagined/main.py

   Alternatively, for more control:

   uvicorn asr_got_reimagined.main:app --reload --host 0.0.0.0 --port 8000

   The API will be available at http://localhost:8000.
