The performance of sentiment analysis models is commonly evaluated using the following metrics:

1. Accuracy: This is the most intuitive performance measure. It is simply a ratio of correctly predicted observations to the total observations.

2. Precision: Precision is the ratio of correctly predicted positive observations to the total predicted positive observations. High precision relates to the low false positive rate.

3. Mean Absolute Error (MAE): This is the average of the absolute difference between the actual and predicted values. It gives an idea of how wrong the predictions were.

4. Mean Squared Error (MSE): This is similar to MAE but noise is exaggerated and larger errors are "punished". It is the average of the squared difference between the actual and predicted values.

Note: While MAE and MSE are commonly used for regression problems, they can also be used in classification problems like sentiment analysis when the output is converted to numerical form.
