Sentiment analysis, also known as opinion mining, is a field of study that involves analyzing and understanding people’s opinions, attitudes, and emotions expressed in text. It has gained significant attention in recent years due to the increasing availability of large amounts of textual data on social media platforms, review websites, and other online sources. To develop accurate sentiment analysis models, researchers and practitioners rely on high-quality datasets that contain labeled examples of text with corresponding sentiment labels. In this article, we will explore 10 highly recommended sentiment analysis datasets that can be used for training and evaluating sentiment analysis models.
1. Stanford Sentiment Treebank: The Stanford Sentiment Treebank is a widely used dataset that provides fine-grained sentiment labels for sentences.
