Need to add Neutral result into the sentiment

that's good to give result between positive (1) and negative (0), but im looking for how to add neutral into the code. Anyone can help?

The project uses models like Naive Bayes, SVM, CNN, LSTM for sentiment analysis. First, examine the existing code to see how binary sentiment (positive/negative) is implemented. Look for model training scripts and data preprocessing to understand the current label encoding. Adding a neutral class likely requires retraining models with a three-class dataset and updating evaluation metrics.
