Sentiment analysis has found its applications in various fields which now help companies to correctly assess and learn from their customers or clients. Sentiment analysis is increasingly used for social media monitoring, brand monitoring, voice of the customer (VoC), customer service, and market research. Sentiment Analysis uses rules-based, hybrid, or machine-learning-based NLP methods and algorithms to learn data from datasets. The data needed for sentiment analysis must be specialized and needed in large quantities.

datasets
Sentiment analysis has found its applications in various fields which now help companies
to correctly assess and learn from their customers or clients. Sentiment analysis is
increasingly used for social media monitoring, brand monitoring, voice of the customer
(VoC), customer service, and market research.
Sentiment Analysis uses rules-based, hybrid, or machine-learning-based NLP methods and
algorithms to learn data from datasets. The data needed for sentiment analysis must be
specialized and needed in large quantities.
The hardest part of the sentiment analysis training process is not finding large amounts of
data; it’s more about finding the relevant datasets. These datasets should cover a wide area of
sentiment analysis and use case applications.

2. Below are some of the most popular datasets for sentiment analysis.
Newsdata.io news dataset
Newsdata.io provides news datasets that contain raw News data in CSV, Excel, and JSON
formats. The dataset contains historical News data exactly as it is posted on the News sources
along with lots of metadata such as the Title of the news, its URL, date and time, publisher,
and much more. You can request the historical news data by filling this form.
The price of the Newsdata.io Historical News dataset starts from $50 and depends on the
number of historical news you want and the length of the time. It is a one time cost that is
liable for a single report
Amazon product data

made available by Stanford Professor Julian McAuley.

out of 10.
Stanford Sentiment Treebank
This dataset contains just over 10,000 Stanford data from Rotten Tomatoes HTML files.
Feelings are rated between 1 and 25, where one is the most negative and 25 is the most
positive.

3. Stanford’s deep learning model was built on representing sentences based on sentence
structure instead of only giving marks based on positive and negative words.
Multi-Domain Sentiment Dataset
This dataset contains positive and negative files for thousands of Amazon products. While
the reviews are for older products, this data set is great to use. The data comes from the
Computer Science Department at Johns Hopkins University.

Sentiment140
Sentiment140 is used to know the sentiment of a brand or product or even a topic on the
social media platform Twitter. Rather than working on a keyword-based approach, which
exploits high precision for lower recall, Sentiment140 works with classifiers created by
machine learning algorithms.
Sentiment140 uses ranking results for individual tweets as well as the traditional surface that
aggregates metrics. Sentiment140 is used for brand management, surveys, and purchasing
planning.
Paper Reviews Data Set

4. The article review dataset contains English and Spanish reviews of computer science and
computer science conferences. The algorithm used predicts the opinions of reviews of
academic articles.
Most sentiment analysis data of this type is sent in Spanish. It has a total of instances of N =
405 rated on a 5 point scale, 2: very negative, 1: neutral, 1: positive, 2: very positive.
The distribution of marks is uniform and there is a difference between the way the article is
rated and the review written by the original reviewer.
Twitter US Airline Sentiment
This sentiment analysis dataset contains tweets from February 2015 about each of the major
U.S. airlines. Each tweet is classified as positive, negative, or neutral.
Features included include Twitter id, sentiment trust score, sentiments, negative reasons,
airline name, number of retweets, name, tweet text, tweet contact details, the date and time
of the tweet, and the location of the tweet.
Sentiment Lexicons For 81 Languages
Sentimental Lexicon for 81 languages contains languages ranging from Afrikaans to Yiddish.
These data include both positive and negative sentimental lexicons for a total of 81
languages.
These lexicons were generated by graph propagation for sentiment analysis based on a
knowledge graph which is a graphical representation of real-world objects and the
relationship between them.
The general idea is that closely related words on a knowledge graph can have similar
polarities. Sentiments were built on the basis of English sentimental lexicons.
