user
a system to classify movie reviews as positive or negative can be designed as follows:

- collect a corpus of movie reviews labeled with their sentiment 
- train a classifier to classify reviews into one of two categories: positive or negative 
- test the classifier on unseen reviews to assess its accuracy 
- introduce scaling and regularization if needed to minimize the risk of overfitting 
- deploy the classifier system and monitor its performance
