Sentiment analysis has found its applications in various fields that are now helping enterprises to estimate and learn from their clients or customers correctly. Sentiment analysis is increasingly being used for social media monitoring, brand monitoring, the voice of the customer (VoC), customer service, and market research. Sentiment analysis uses NLP methods and algorithms that are either rule-based, hybrid, or rely on machine learning techniques to learn data from datasets.

The data needed in sentiment analysis should be specialised and are required in large quantities. The most challenging part about the sentiment analysis training process isn’t finding data in large amounts; instead, it is to find the relevant datasets. These data sets must cover a wide area of sentiment analysis applications and use cases.

Below are listed some of the most popular datasets for sentiment analysis.



This list is in no particular order.

Amazon Product Data

Amazon product data is a subset of a large 142.8 million Amazon review dataset that was made available by Stanford professor, Julian McAuley. This sentiment analysis dataset contains reviews from May 1996 to July 2014. The dataset reviews include ratings, text, helpfull votes, product description, category information, price, brand, and image features.

Stanford Sentiment Treebank

This dataset contains just over 10,000 pieces of Stanford data from HTML files of Rotten Tomatoes. The sentiments are rated between 1 and 25, where one is the most negative and 25 is the most positive. The deep learning model by Stanford has been built on the representation of sentences based on the sentence structure instead just giving points based on the positive and negative words. 

For example:

The Interview was neither that funny nor that witty.

Even if there are words like funny and witty, the overall structure is a negative type.

Multi-Domain Sentiment Dataset

This dataset contains positive and negative files for thousands of Amazon products. Although the reviews are for older products, this data set is excellent to use. The data derives from the Department of Computer Science at John Hopkins University.

The reviews contain ratings from 1 to 5 stars that can be converted to binary as needed.
