Title: Implement AI-Powered Academic Paper Matching System

Description:

This PR introduces a comprehensive AI-powered academic paper matching system. The system is designed to connect researchers with relevant academic papers based on their interests, expertise, and research background. It employs advanced natural language processing and machine learning techniques to provide personalized paper recommendations.

Key Features Implemented:

1. Intelligent Profile Analysis: Automatically analyzes researcher profiles to understand their interests and expertise.
2. Semantic Paper Matching: Uses advanced NLP techniques to match papers with researchers.
3. Personalized Recommendations: Delivers tailored paper suggestions based on individual research profiles.
4. RESTful API Integration: Easy-to-use API endpoints for seamless integration.
5. Scalable Architecture: Designed to handle large volumes of papers and users.
6. Real-time Updates: Dynamic updating of recommendations as new papers are added.

Technical Details:

• Backend: Python 3.8+
• API Framework: Flask
• ML/NLP: scikit-learn, NLTK, TensorFlow
• Data Processing: pandas, numpy
• Database: SQLite (default), PostgreSQL (optional)
• Testing: pytest
• Documentation: Sphinx

Major Components:

1. Data Preprocessing: Implemented in preprocessing/data_preprocessor.py
2. Profile Analyzer: Located in models/profile_analyzer.py
3. Semantic Matcher: Implemented in models/semantic_matcher.py
4. Recommender System: Found in models/recommender.py
5. API Routes: Defined in api/routes.py
6. Utility Functions: Available in utils/helpers.py

Additional Implementations:

• Comprehensive test suite in the tests/ directory
• Sample data generator in data_generator.py
• Configuration management in config.py
• Detailed documentation in the docs/ directory

Performance Metrics:

• Implemented evaluation metrics including Precision@K, Recall@K, MAP, and NDCG

This PR also includes:

• A comprehensive README.md with detailed setup instructions, API usage examples, and contribution guidelines
• Requirements file for easy dependency management
• Proper code commenting and docstrings for better maintainability

Testing:

• All new components have corresponding unit tests
• Integration tests have been added to ensure system cohesion
• Current test coverage is over 80%

Next Steps:

• Integration with external academic databases
• Implementation of the user feedback system
• Enhanced recommendation algorithms using deep learning techniques

Please review the changes and provide feedback. Special attention should be given to:

1. The matching algorithm in models/semantic_matcher.py
2. API design and security measures in api/routes.py
3. Data preprocessing steps in preprocessing/data_preprocessor.py
4. Overall system architecture and scalability

Let me know if any further changes or clarifications are needed.
