Sentiment Analysis, also known as opinion mining or emotion AI, is a sub-field of Natural Language Processing (NLP) that tries to identify and extract subjective information from source materials. It is commonly used to determine the attitude of a speaker or a writer with respect to some topic or the overall contextual polarity of a document.
For example, if a company wants to understand the public's opinion about its new product, it can use Sentiment Analysis to analyze the comments and reviews left by customers on social media platforms, forums, or e-commerce websites. The analysis can categorize these comments into positive, negative, or neutral sentiments, providing the company with valuable feedback to improve its product.
In the context of cloud computing, Tencent Cloud offers a Sentiment Analysis API as part of its Natural Language Processing services. This API can help businesses quickly understand public opinions and market trends, enabling them to make data-driven decisions.
