## 🚀 Key Features

- Dual Interface Options:
  - Web-based interface using Streamlit
  - Command-line interface for direct interaction
- Comprehensive Drug Analysis:
  - Drug interaction detection
  - Conflict identification
  - Similar drug suggestions
  - Alternative medication recommendations
- Advanced Technology Stack:
  - RDF/OWL ontology for knowledge representation
  - Groq LLM integration for natural language processing
  - Agent-based architecture using Langgraph for modular analysis
  - Structured logging system

## 🛠️ Technical Requirements

- Python 3.x
- Groq API key
- Required Python packages:
  - rdflib
  - langchain
  - python-dotenv
  - langchain-community
  - langchain-groq
  - langgraph
