Abstract

In this project "BrieflyAI", a comprehensive news intelligence system that aggregates and analyzes information from multiple sources including Google News and Reddit discussions. The system employs advanced natural language processing techniques using Groq's LLaMA models to generate structured summaries and insights from real-time data. BrieflyAI addresses the challenge of information overload by providing users with concise, well-structured analyses of topics across different media platforms. The system integrates web scraping capabilities, rate-limited API calls, and a user-friendly Streamlit interface to deliver comprehensive news intelligence. Experimental results demonstrate the system's effectiveness in processing multiple topics simultaneously while maintaining data quality and providing actionable insights.

Introduction

In today's information-rich environment, staying updated with current events across multiple platforms presents significant challenges. Traditional news consumption methods often lead to information silos, where users miss crucial discussions happening on social media platforms like Reddit. BrieflyAI was developed to bridge this gap by creating an integrated analysis system that combines traditional news sources with community-driven discussions.

Problem Statement

The primary challenges addressed by this system include:

• Information Fragmentation: News and discussions are scattered across different platforms
• Time Constraints: Manual analysis of multiple sources is time-consuming
• Context Loss: Lack of comprehensive analysis that combines multiple perspectives
• Scalability Issues: Difficulty in processing multiple topics simultaneously

System Overview

BrieflyAI implements a microservices architecture that combines:

• Web Scraping Module: For extracting news headlines from Google News
• Reddit Analysis Module: For processing community discussions and sentiment
• AI-Powered Summarization: Using advanced LLM models for content analysis
• Interactive Dashboard: Streamlit-based user interface for seamless interaction

Methodology

2.1 System Architecture

The system follows a modular architecture with distinct components for different functionalities:

2.2 Data Collection Strategy

News Scraping Module

The news scraping module utilizes BrightData's web unlocker service to access Google News:

def generate_valid_news_url(keyword: str) -> str:
    """
    Generate a Google News search URL for a keyword with optional sorting by latest
    
    Args:
        keyword: Search term to use in the news search
        
    Returns:
        str: Constructed Google News search URL
    """
    q = quote_plus(keyword)
    return f"https://news.google.com/search?q={q}&tbs=sbd:1"

def scrape_with_brightdata(url: str) -> str:
    """Scrape a URL using BrightData with improved error handling"""
    
    # Validate environment variables
    api_key = BRIGHTDATA_API_KEY
    zone = WEB_UNLOCKER_ZONE
    
    if not api_key:
        raise ValueError("BRIGHTDATA_API_KEY environment variable is not set")
    if not zone:
        raise ValueError("BRIGHTDATA_WEB_UNLOCKER_ZONE environment variable is not set")
    
    # Validate URL
    if not url or not url.startswith(('http://', 'https://')):
        raise ValueError("Invalid URL provided")
    
    headers = {
        "Authorization": f"Bearer {api_key}",
        "Content-Type": "application/json"
    }

    # Updated payload based on BrightData API documentation
    payload = {
        "zone": zone,
        "url": url,
        "format": "raw",
        "country": "US",  # Add country if required
        "render": False   # Set to True if you need JavaScript rendering
    }
    
    try:
        print(f"Attempting to scrape: {url}")
        print(f"Using zone: {zone}")
        
        response = requests.post(
            "https://api.brightdata.com/request", 
            json=payload, 
            headers=headers,
            timeout=30  # Add timeout
        )
        
        # Log response details for debugging
        print(f"Response status: {response.status_code}")
        print(f"Response headers: {dict(response.headers)}")
        
        if response.status_code == 400:
            # Try to get more specific error details
            try:
                error_detail = response.json()
                print(f"BrightData error details: {error_detail}")
                raise HTTPException(
                    status_code=500, 
                    detail=f"BrightData API error: {error_detail.get('message', 'Bad Request')}"
                )
            except:
                print(f"Response text: {response.text}")
                raise HTTPException(
                    status_code=500, 
                    detail=f"BrightData API error: 400 Bad Request - {response.text}"
                )
        
        response.raise_for_status()
        return response.text
        
    except requests.exceptions.RequestException as e:
        print(f"Request exception: {str(e)}")
        raise HTTPException(status_code=500, detail=f"BrightData error: {str(e)}")

Reddit Analysis Module

For Reddit data collection, the system implements MCP (Model Context Protocol) integration:

@retry(
    stop=stop_after_attempt(3),
    wait=wait_exponential(multiplier=1, min=15, max=60),
    retry=retry_if_exception_type(MCPOverloadedError),
    reraise=True
)
async def process_topic(agent, topic: str):
    async with mcp_limiter:
        messages = [
            {
                "role": "system",
                "content": f"""You are a Reddit analysis expert. Use available tools to:
                1. Find top 2 posts about the given topic BUT only after {two_weeks_ago_str}, NOTHING before this date strictly!
                2. Analyze their content and sentiment
                3. Create a summary of discussions and overall sentiment"""
            },
            {
                "role": "user",
                "content": f"""Analyze Reddit posts about '{topic}'. 
                Provide a comprehensive summary including:
                - Main discussion points
                - Key opinions expressed
                - Any notable trends or patterns
                - Summarize the overall narrative, discussion points and also quote interesting comments without mentioning names
                - Overall sentiment (positive/neutral/negative)"""
            }                   
        ]
        
        try:
            response = await agent.ainvoke({"messages": messages})
            return response["messages"][-1].content
        except Exception as e:
            if "Overloaded" in str(e):
                raise MCPOverloadedError("Service overloaded")
            else:
                raise

2.3 Natural Language Processing Pipeline

The system employs Groq's LLaMA models for content analysis and summarization:

def summarize_with_groq_structured(api_key: str, headlines: str) -> str:
    """
    Summarize headlines into a structured format for UI display using GROQ.
    """
    system_prompt = """
    You are a professional news analyst creating structured summaries for web display.

    Transform the provided headlines into a well-organized, comprehensive summary with:

    1. **Executive Summary**: Brief overview of the main themes
    2. **Key Stories**: Major headlines with detailed explanations
    3. **Analysis**: What these stories mean and their significance
    4. **Trends**: Patterns or connections between different stories

    Format guidelines:
    - Use clear markdown headings (##, ###)
    - Present key points as bullet points
    - Include specific details and context
    - Maintain professional, informative tone
    - Focus on clarity and readability
    - Make it comprehensive but digestible

    Create a structured report that would be suitable for display on a news dashboard or summary page.
    """

    try:
        llm = ChatGroq(
            model=LLAMA_70b_model,
            api_key=api_key,
            temperature=TEMPERATURE,
            max_tokens=MAX_TOKEN_1
        )

        response = llm.invoke([
            SystemMessage(content=system_prompt),
            HumanMessage(content=f"Headlines to analyze:\n\n{headlines}")
        ])

        return response.content
    except Exception as e:
        raise HTTPException(status_code=500, detail=f"GROQ error: {str(e)}")
