🤖 Enhanced Ensemble Meme & Text Analyzer

An advanced AI system that combines multiple state-of-the-art models to analyze memes, social media posts, and visual content for harmful or hateful content detection.

🎯 Key Features

🧠 Advanced Ensemble Architecture

Fine-tuned BERT: 93% accuracy sentiment analysis
SigLIP-Large: Best-in-class vision-language understanding
Multi-engine OCR: EasyOCR + PaddleOCR for robust text extraction
Intelligent Fusion: Weighted ensemble with attention mechanisms

🔍 Comprehensive Analysis

✅ Sentiment Analysis: Emotion and tone detection in text
✅ Hate Speech Detection: Visual and textual harmful content identification
✅ OCR Text Extraction: Read text from memes and images
✅ Social Media Integration: Analyze content from URLs
✅ Risk Stratification: Multi-level risk assessment (Safe/Low/Medium/High)
✅ Explainable AI: Clear reasoning for every prediction

🎛️ Multiple Input Modes

Text Only: Analyze pure text content
Image Only: Process images with automatic OCR
URL: Fetch and analyze social media posts
Text + Image: Combined multimodal analysis
