This is the official model that achieved 94% accuracy by preserving and enhancing emojis using the copyrighted EMOJIXT dictionary — instead of removing them like most models do.

Key Innovation

We replace emojis with sentiment-rich words:

• Happy emoji → happy joyful
• Crying emoji → crying sad
• Heart emoji → love adore
• Thumbs up emoji → thumbs up good

Result: +9% accuracy gain over state-of-the-art baselines.
