Sentiment Analysis

Sentiment analysis is an NLP technique that involves determining the sentiment or emotional tone behind a piece of text, such as a review, tweet, or customer feedback. The main goal of sentiment analysis is to categorize the sentiment expressed in the text as positive, negative, or neutral. This process is important for understanding public opinion, making informed business decisions, monitoring brand reputation, and evaluating customer satisfaction.

In the era of social media and online reviews, sentiment analysis helps businesses understand customer feedback at scale, enabling them to identify areas of improvement and improve customer experience. It assists in monitoring and managing brand perception, as well as predicting market trends based on sentiment shifts.

Several datasets are available for training and evaluating sentiment analysis models. These datasets are often labeled with sentiment labels (positive, negative, neutral) to facilitate supervised machine learning. Some popular datasets include:

• IMDb Movie Reviews: A dataset containing movie reviews with binary sentiment labels (positive/negative). It is widely used for sentiment analysis model benchmarking.
• Amazon Product Reviews: This dataset contains reviews of various products sold on Amazon, and the reviews are annotated with sentiment labels.
