# StockDocs Project Overview
This document provides a comprehensive overview of the StockDocs financial news analysis platform, including detailed information about each project component, file structures, and how to begin working with the system.
## Project Architecture
StockDocs is a sophisticated system designed to collect, process, and analyze financial news from multiple sources. The platform consists of several interconnected components that work together to transform raw news content into valuable market intelligence.
```

| | | |
+--------------+ +-------------------+
```
## Project Components
### 1. Scraper
**Location:** `scraper/`
The Scraper component is responsible for collecting financial news and articles from multiple sources including major news outlets, financial publications, and market analysis services. It uses RSS feeds to gather content and stores the articles in a structured directory hierarchy for easy access by other components of the system.
#### Key Features:
- RSS Feed Integration: Supports multiple financial news sources through RSS feeds
- Automated Scraping: Regularly fetches and processes new articles from configured feeds
- Structured Storage: Organizes articles in a directory structure by news outlet
- Duplicate Detection: Prevents re-processing of already collected articles
- Caching Mechanism: Maintains a cache of processed articles to optimize performance
#### File Structure:
```

### 2. Article Server
**Location:** `articleServer/`
A Flask-based HTTP server that provides access to news articles stored in a directory structure, with time-based filtering and outlet-specific querying capabilities.
#### Key Features:
- Time-based filtering: Query articles by hour, day, week, or month
- Outlet-specific querying: Filter articles by news source
- Content retrieval: Get full article content by file path
- RESTful API: Clean interfaces for integration with external systems
#### File Structure:

### 3. AI Processor
**Location:** `ai_processor/`
An AI-powered analytics engine designed to process financial news articles and extract meaningful insights, sentiment analysis, and market indicators from collected content.
#### Key Features:
- Sentiment Analysis: Determine positive, negative, or neutral sentiment of news articles
- Topic Classification: Categorize articles by financial topics
- Entity Extraction: Identify key entities mentioned in articles (stocks, companies, people, organizations)

### Prerequisites
- Docker installed
- Python 3.8+
- Git
### Setup Instructions
1. **Clone the repository:**
```bash
git clone <repository-url>
cd StockDocs
```
2. **Build and run containers:**
```bash
docker-compose up --build
```
3. **Project-specific setup:**
- Each project has its own `README.md` with detailed setup instructions
- Check individual project directories for specific requirements
## Project Dependencies
### Common Dependencies
- Python 3.8+
- Docker
- Various Python packages (listed in requirements.txt files)
### Inter-project Relationships
- `scraper/` feeds articles to `ai_processor/`
- `ai_processor/` generates embeddings that `embedding/` processes
- `articleServer/` serves articles processed by `ai_processor/`
- `MCPServer/` provides API access to all components
## Development Workflow
1. **Start all services:**
```bash
docker-compose up --build
```
2. **Work with individual projects:**
- Navigate to project directory
- Check `README.md` for specific instructions
- Make changes and rebuild as needed
3. **Testing:**
- Each project includes its own testing setup
- Integration tests may be needed for cross-project functionality
## API Endpoints
### articleServer/
- `/articles` - Get all articles
- `/articles/<id>` - Get specific article
- `/search` - Search articles by query
### MCPServer/
- Exposes various endpoints through Model Context Protocol
- See `openapi.json` for complete specification
## Configuration
### Environment Variables
Each project may require specific environment variables. Check individual `README.md` files for details.
### Authentication
The system now supports API key authentication for connections to the centralized AI service at `http://example.com:4000`. To enable authentication:
1. Set the `AI_SERVICE_API_KEY` environment variable with your API key
2. All connections to the AI service will automatically include the `Authorization: Bearer {api_key}` header
### Data Storage
- Articles are stored in the scraper component
- Processed data flows through the ai_processor
- Embeddings are generated and stored in the embedding component
## Troubleshooting
### Common Issues
1. **Docker build failures:** Ensure Docker is running and check `Dockerfile` syntax
2. **Python dependency issues:** Run `pip install -r requirements.txt` in each project
3. **Port conflicts:** Check `docker-compose.yml` for port mappings
4. **Service startup issues:** Check individual project logs
### Logs
- View logs with `docker-compose logs <service-name>`
- Check individual project logs for detailed error information
