Feature Importance

The model identifies important words/phrases for each sentiment class. See results.json for the complete feature importance analysis.

Limitations

The model is trained specifically on game reviews and may not generalize well to other domains
Performance may vary on reviews with sarcasm or nuanced sentiments
The model treats text as bag-of-words and doesn't capture word order

Training Details

This model was trained as part of a game review sentiment analysis project. For more information, see the project repository.
