Description

A neural network for sarcasm detection trained on the Reddit Sarcasm Database.

Methods and Models

• Dataset: Reddit Sarcasm Database
• Approach: Neural network-based sarcasm detection
• Additional Experimentation:
  • Sentiment Analysis: Attempted to use a theory that sarcastic sentences contain both highly positive and highly negative sentiments close together, but it did not improve results.
  • Larger Dataset: No significant improvement observed despite using an expanded Reddit dataset.

Results

• Accuracy: ~57%
  • The best academic results found were in the 60% range.
  • Yahoo claims to have a proprietary model with 80% accuracy.

Future Improvements

• Contextual Analysis: Incorporating preceding comments might enhance sarcasm detection.
• Multimodal Features: Using audio could simplify the problem and significantly improve accuracy beyond 80%.
