2. What Is NLP and How Is It Used in Sentiment Analysis?

Natural Language Processing (NLP) is a branch of artificial intelligence that helps computers understand human language. It is crucial for sentiment analysis as it identifies customer sentiments in feedback.

NLP employs techniques like tokenization (breaking text into words) and stemming (reducing words to their root form) to simplify analysis. For example, sentiment classification often uses logistic regression or advanced deep learning methods, such as recurrent neural networks, to determine whether the sentiment is positive, negative, or neutral.

These techniques help you assess customer sentiments on social media and product reviews, allowing for improved responses and greater satisfaction.

3. Types of Sentiment Analysis

Sentiment analysis has several types, including sentiment classification, emotional analysis, and aspect-based sentiment analysis. Each is designed to meet specific business needs.

Sentiment classification categorizes text into positive, negative, or neutral sentiments, helping you gauge overall customer satisfaction. Emotional analysis identifies specific emotions like joy, anger, or sadness, revealing deeper customer sentiments. Aspect-based sentiment analysis focuses on particular features of your products or services, offering insights into what customers value or critique.

Together, these methods enable you to monitor brand reputation on social media and adapt your strategies for enhanced customer experiences.
