Sentiment Analysis, subset of Natural Language Processing NLT; types and overviews.

 

Sentiment Analysis is a subset of Natural Language Processing NLP, that is used in the application of algorithms which helps computers to further understand and interpret human language. 

Sentiment analysis is used in a variety of applications, including social media monitoring, customer feedback analysis, and market research. It can help businesses and organizations understand how their customers feel about their products or services, identify areas for improvement, and make data-driven decisions.

Sentiment analysis, also known as opinion mining, is a type of NLP that involves the use of algorithms and models to identify and extract subjective information from text. This includes identifying the sentiment (positive, negative, or neutral) expressed in a piece of text, as well as the emotions, opinions, and attitudes of the author.

There are several types of sentiment analysis techniques, including:

1. Rule-based sentiment analysis: Is the approach that involves the use of predefined rules and lexicons to identify sentiment in text. It relies on a set of pre-defined rules and dictionaries to identify positive, negative, or neutral sentiment.

2. Machine learning-based sentiment analysis: This approach also involves the use of machine learning algorithms to train models on large datasets of labeled text. The models learn to identify sentiment based on patterns and features in the data.

3. Hybrid sentiment analysis: This approach can be said to combine both rule-based and machine learning-based techniques to improve the accuracy of sentiment analysis.

Above all, Sentiment Analysis is definitely used in a variety of applications, including social media monitoring, customer feedback analysis, and market research. It can help businesses and organizations understand how their customers feel about their products or services, identify areas for improvement, and make data-driven decisions.
