Understanding AI Sentiment Analysis

What Is AI Sentiment Analysis?

AI sentiment analysis refers to the application of artificial intelligence algorithms to interpret and quantify the sentiment expressed in written text. By leveraging natural language processing (NLP), machine learning, and deep learning, organizations are able to determine the emotional tone behind a body of text – categorizing sentiments as positive, negative, or neutral. This capability has found utility across diverse domains—ranging from evaluating customer feedback and enhancing marketing strategies, to monitoring brand reputation and conducting social media analysis.

This process generally involves parsing text data through various techniques, enabling businesses to extract useful insights from vast amounts of unstructured information such as customer reviews, social media posts, and internal communications.
