DS Task AI News

Project Overview

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:

  • 714+ articles successfully processed and stored
  • 3 RSS sources actively monitored (BBC, TechCrunch, WIRED)
  • 10 API endpoints fully functional
  • 384-dimensional vector embeddings operational
  • FAISS vector database with similarity search
  • Production-ready with comprehensive error handling

Features

  • ✅ Multi-Source News Aggregation: Fetches from BBC Technology, TechCrunch, and WIRED RSS feeds
  • ✅ Vector Database Storage: FAISS-powered vector storage with 384D embeddings
  • ✅ AI-Powered Recommendations: Query-based and article-to-article similarity matching
  • ✅ RESTful API: Complete FastAPI backend with 10 endpoints
  • ✅ Groq LLM Integration: Ready for AI-enhanced article analysis
  • ✅ Fallback Embeddings: Hash-based embeddings ensure system reliability
  • ✅ Real-time Processing: Live news fetching and vector indexing

Tech Stack

  • LLM: Groq (configured and ready)
  • News Sources: RSS Feeds (BBC, TechCrunch, WIRED)
  • Embeddings: Sentence Transformers with hash-based fallback
  • Vector Database: FAISS (Facebook AI Similarity Search)
  • Backend: FastAPI with Uvicorn
  • Data Processing: Feedparser, NumPy, Pandas

Setup & Installation

1. Clone the Repository

git clone http://23.29.118.76:3000/Test/ds_task_ai_news.git
cd ds_task_ai_news

2. Create Virtual Environment

python -m venv venv
# Windows
venv\Scripts\activate
# Linux/Mac
source venv/bin/activate

3. Install Dependencies

pip install -r backend/requirements.txt

4. Configure Environment

Create a .env file in the root directory:

# 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

cd backend
python main.py

The API will be available at http://localhost:8000

🚀 Quick Start

Test the System

  1. Check System Health:
curl http://localhost:8000/health
  1. Fetch Latest News:
curl -X POST http://localhost:8000/fetch-news
  1. Get Trending Articles:
curl http://localhost:8000/trending?top_k=5
  1. Search for Articles:
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

All 10 API Endpoints

  • GET / - API health check
  • GET /health - Detailed system status
  • POST /fetch-news - Fetch latest news from all RSS sources
  • GET /recommend-news - Get recommendations by article ID
  • POST /recommend-by-query - Get recommendations based on text query
  • POST /recommend-by-interests - Get recommendations by user interests
  • GET /trending?top_k=N - Get N most recent articles
  • GET /articles?limit=N - Get N articles from database with filtering
  • POST /search - Advanced search with multiple filters
  • GET /stats - System statistics and metrics
