What does sentiment analysis primarily evaluate?

Sentiment analysis is a technique used to determine the emotional tone behind a series of words, which helps understand the sentiment expressed in written or spoken language. This process involves assessing whether the sentiment conveyed is positive, negative, or neutral. By evaluating the emotions that words, phrases, and even entire texts express, sentiment analysis can provide insights into public opinion, customer emotions, or the general attitude towards a product, service, or topic.

The application of sentiment analysis spans various fields, including marketing, customer service, social media monitoring, and even politics. By analyzing customer feedback, brand mentions, or social media posts, businesses can gauge public perception and make data-driven decisions aimed at improving customer satisfaction and engagement.

The other choices refer to different areas that sentiment analysis does not cover, such as financial performance, accuracy of models, or linguistic structures, which are separate domains of analysis or study.
