# 🔬 Automated Consensus Analysis API

A comprehensive HuggingFace Spaces API for automated peer review consensus analysis using LLMs and search-augmented verification.

## 🌟 Features

- **Critique Extraction**: Extract structured critique points from peer reviews using Gemini 2.0
- **Disagreement Detection**: Identify conflicts and disagreements between reviewers
- **Search-Augmented Verification**: Retrieve supporting/contradicting evidence from academic sources
- **Disagreement Resolution**: AI-powered resolution using DeepSeek-R1 with reasoning
- **Meta-Review Generation**: Comprehensive meta-reviews synthesizing all analyses
- **Rate Limiting**: 10 requests per minute per client
- **Queue Management**: Up to 3 concurrent pipeline executions
- **Progress Tracking**: Real-time status updates for long-running tasks

## 🚀 Quick Start

### Local Development

1. **Clone and setup**

```bash
cd api
python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate
pip install -r requirements.txt
```

2. **Configure environment**

```bash
cp .env.example .env
# Edit .env with your API keys
```

3. **Run the application**

```bash
python app.py
```

Visit `http://localhost:7860` to access the Gradio interface.

### HuggingFace Spaces Deployment

1. **Create a new Space**

   - Go to [HuggingFace Spaces](https://huggingface.co/spaces)
   - Click "Create new Space"
   - Select "Gradio" as SDK

2. **Upload files**

   - Upload all files from the `api/` directory
   - Ensure `requirements.txt` and `app.py` are in the root

3. **Configure secrets**

   - Go to Space Settings → Repository secrets
   - Add the following secrets:
     - `GEMINI_API_KEY`
     - `OPENROUTER_API_KEY`
     - `TAVILY_API_KEY`
     - `SERPAPI_API_KEY`

4. **Deploy**
   - The Space will automatically build and deploy

## 🔍 Pipeline Stages

1. **Critique Extraction** (Gemini 2.0)

   - Extracts structured critique points
   - Categories: Methodology, Experiments, Clarity, Significance, Novelty

2. **Disagreement Detection** (Gemini 2.0)

   - Compares all review pairs
   - Assigns disagreement scores (0-1)
   - Identifies specific conflict points

3. **Search & Retrieval** (LangChain + Multi-Search)

   - SoTA research discovery
   - Evidence validation
   - Sources: Semantic Scholar, arXiv, Google Scholar, Tavily

4. **Disagreement Resolution** (DeepSeek-R1)

   - Validates critique points
   - Accepts/rejects based on evidence
   - Provides resolution summaries

5. **Meta-Review Generation** (DeepSeek-R1)
   - Synthesizes all analyses
   - Provides final verdict
   - Offers actionable recommendations
