Sentiment Analysis, also known as Opinion Mining, is a natural language processing technique that involves the extraction and analysis of subjective information from text or speech. It aims to determine the sentiment or emotional tone expressed in a piece of content, such as positive, negative, or neutral.
Sentiment Analysis uses various computational methods, including machine learning algorithms and linguistic rules, to analyze text or speech and identify sentiment-bearing elements such as words, phrases, or emojis. These elements are then assigned sentiment scores based on predefined sentiment lexicons or trained models. The sentiment scores are aggregated to determine the overall sentiment of the content.
Sentiment Analysis provides valuable insights into the opinions, attitudes, and emotions of customers, users, or the general public. It enables businesses to understand customer feedback, gauge public sentiment towards products or services, identify emerging trends, and make data-driven decisions.
