What is the purpose of sentiment analysis?

The purpose of sentiment analysis is to assess the sentiment expressed in a text. This involves evaluating the emotions or opinions conveyed in written content, which can range from positive to negative or neutral. Organizations and businesses utilize sentiment analysis to gain insights into customer feedback, social media commentary, or product reviews. By identifying the sentiment behind the words, it helps in understanding consumer attitudes and improving decision-making processes.

Understanding sentiment can aid in shaping marketing strategies, enhancing customer service, and managing brand reputation, as it delivers a deeper comprehension of how individuals feel about a topic or product. This approach is particularly relevant in today's data-driven world, where capturing customer emotions can significantly influence business outcomes.

Other options such as identifying named entities, determining grammatical roles, or visualizing data from images do not specifically focus on emotional or opinion-based analysis, making them less relevant in the context of sentiment analysis.
