What does sentiment analysis analyze?

Sentiment analysis specifically focuses on understanding and interpreting the emotional tone behind the words used in text. It involves processing and analyzing textual data to determine whether the sentiment expressed is positive, negative, or neutral. This analysis can be applied to various sources of text, including social media posts, product reviews, and customer feedback. By capturing the nuances of language and emotion, sentiment analysis can provide valuable insights into public perception, customer satisfaction, and emotional responses, making it a powerful tool in fields such as marketing, customer service, and social media monitoring.

The other options, while relevant to data analytics, do not align with the core objective of sentiment analysis. Statistical data trends pertain to numerical analysis and pattern recognition, numerical data patterns also deal with quantitative data, and data quality assessments focus on the accuracy and integrity of data rather than its emotional content. These concepts are crucial in their respective areas but do not capture the essence of sentiment analysis.
