## Project Overview
DS Task AI News is an AI-powered news retrieval system that gathers news articles from various online sources, stores them in a vector database, and enables users to discover relevant articles based on their interests. The system uses advanced AI techniques to find and recommend related news articles dynamically.
DS Task AI News is a fully functional AI-powered news retrieval system that aggregates news articles from multiple RSS sources, stores them in a vector database, and provides intelligent recommendations. The system features a complete REST API, vector-based similarity search, and AI-ready architecture for enhanced news analysis.
## ✅ Current Status: FULLY OPERATIONAL
**System Metrics:**
- **238+ articles** successfully processed and stored
- **3 RSS sources** actively monitored (BBC, TechCrunch, WIRED)
- **8 API endpoints** fully functional

### 2. Set Up the Backend
### 2. Create Virtual Environment
```bash
python -m venv venv
# Windows
venv\Scripts\activate
# Linux/Mac
source venv/bin/activate
```
### 3. Install Dependencies
```bash
pip install -r backend/requirements.txt
```
### 4. Configure Environment
Create a `.env` file in the root directory:
```env
# API Keys (Optional - system works without them)
GROQ_API_KEY=your_groq_api_key_here
COHERE_API_KEY=your_cohere_api_key_here
# RSS Feed Sources
RSS_FEEDS=https://feeds.bbci.co.uk/news/technology/rss.xml,https://techcrunch.com/feed/,https://www.wired.com/feed/rss
# Server Settings
HOST=0.0.0.0
PORT=8000
DEBUG=true

### 5. Start the Server
```bash
cd backend
pip install -r requirements.txt
python main.py
```
## Fetching News Using RSS Feeds
The API will be available at `http://localhost:8000`
* News is aggregated from RSS feeds of different news sources.
* The `news_fetcher.py` script pulls data from RSS feeds, extracts relevant information, and stores it in the database.
## 🚀 Quick Start
### **Example RSS Fetching Code (Python)**
### Test the System
```python
import feedparser
def fetch_rss_news(feed_url):
feed = feedparser.parse(feed_url)
articles = []
for entry in feed.entries:
articles.append({
"title": entry.title,
"content": entry.summary,
"date": entry.published,
"slug": entry.title.lower().replace(" ", "-"),
"categories": ["Technology", "AI and Innovation"],
"tags": ["AI", "Technology", "Innovation"]
})
return articles
1. **Check System Health:**
```bash
curl http://localhost:8000/health
```
## API Endpoints
2. **Fetch Latest News:**
```bash
curl -X POST http://localhost:8000/fetch-news
```
* `GET /fetch-news`: Fetches news from RSS feeds.
* `GET /recommend-news?article_id=xyz`: Retrieves similar news based on the selected article.
3. **Get Trending Articles:**
```bash
curl http://localhost:8000/trending?top_k=5
```
4. **Search for Articles:**
```bash
curl -X POST http://localhost:8000/recommend-by-query \
-H "Content-Type: application/json" \
-d '{"query": "artificial intelligence", "top_k": 3}'
```
## 📡 RSS News Fetching
The system automatically fetches news from multiple sources:
* **BBC Technology**: Latest tech news and innovations
* **TechCrunch**: Startup and technology industry news
* **WIRED**: Science, technology, and digital culture
### Production RSS Implementation
Our implementation includes:
- **Error handling** for unreliable feeds
- **Content cleaning** (HTML tag removal, truncation)
- **Duplicate detection** using content hashing
- **Source attribution** and metadata preservation
- **Rate limiting** and respectful fetching
## 🔌 API Endpoints
### Core Endpoints
* `GET /` - API health check
* `GET /health` - Detailed system status
* `POST /fetch-news` - Fetch latest news from all RSS sources
* `GET /trending?top_k=N` - Get N most recent articles
* `GET /articles?limit=N` - Get N articles from database
* `POST /recommend-by-query` - Get recommendations based on text query
* `GET /stats` - System statistics and metrics
### Example Responses
**System Health:**
```json
{
"status": "healthy",
"vector_store": {
"total_articles": 238,
"index_dimension": 384,
"index_exists": true
}
}
```
**News Fetching:**
```json
{
"success": true,
"message": "Successfully fetched and stored news articles",
"articles_count": 119,
"articles_stored": 119,
"total_articles": 238
}
```
