Case Study: Sentiment Analysis

Sentiment analysis is a common application of NLP in which the goal is to determine the sentiment of a given text. Deep learning models, particularly RNNs and transformers, have shown remarkable performance in this task.

How It Works

1. Data Preprocessing: Clean and tokenize the text data.
2. Model Training: Use a pre-trained model or train your own on a labeled dataset.
3. Prediction: Analyze new text to predict sentiment.
