Elevator to the Moon
This dataset is widely used in AI and Natural Language Processing (NLP) research. It contains two fields: the movie review text and its sentiment label—manually categorized by humans as positive (1) or negative (0). Manual labeling is time-consuming and expensive, but modern large language models (LLMs) can now interpret and classify review sentiments with up to 98% accuracy.
Note: this dataset can also be found from the Hugging Face website.
