Code Explanation:
This program is designed to revolutionize film critique by automating sentiment analysis on movie reviews using a simple machine learning model, specifically a Multinomial Naive Bayes classifier.
- Importing Libraries: We start by importing necessary libraries.
sklearnfor model training and metrics,pandasfor data manipulation. - Dataset Preparation: We create a dummy dataset containing movie reviews and their sentiments (positive=1, negative=0) to mimic a real-world scenario.
- Dataset Transformation into a DataFrame: The dataset is transformed into a DataFrame for more straightforward manipulation using
pandas. - Train-Test Split: The dataset is split into training and testing sets with 75% of data used for training the model, and 25% used for testing it.
- Text Vectorization: Since machine learning models don’t understand text data, we convert our text data into numerical data using
CountVectorizer. - Model Training: A Multinomial Naive Bayes model is trained on the vectorized training dataset. This model is chosen for its suitability for classification with discrete features (e.g., word counts for text classification).
- Sentiment Prediction: The trained model is then used to predict sentiments on the unseen test dataset.
- Accuracy Computation: Finally, we compute the accuracy of the model, which tells us what fraction of the reviews were correctly classified.
This project showcases the combination of natural language processing (NLP) techniques with machine learning models to automatize opinion mining in film critiques, offering a practical application that could greatly enhance content analysis in the film industry.
