1. MovieLens

MovieLens is a popular dataset for recommender systems in the movie domain. It contains over 27,000 movies and 138,000 ratings from 1,000 users. The ratings range from 1 to 5, with 5 being the highest rating. The dataset also includes movie metadata such as genres, release year, and title.

This dataset has been used in many research papers and competitions, making it a reliable and well-studied dataset. It is also easy to access and download, with various versions available on the MovieLens website.

2. Amazon Reviews

Amazon Reviews is a dataset containing over 130 million reviews from Amazon customers. The reviews cover a wide range of products, including books, electronics, and clothing. The dataset also includes product metadata such as category, price, and brand.

This dataset is useful for recommender systems that operate in the e-commerce domain. It provides a large and diverse set of reviews and products, allowing for more accurate recommendations. However, the dataset is quite large and may require significant processing power and storage.

3. Last.fm

Last.fm is a music streaming service that provides a dataset of user listening histories. The dataset contains over 1 billion scrobbles from 2 million users and 1 million artists. The scrobbles represent the number of times a user has listened to a particular artist.

This dataset is useful for music recommender systems, as it provides a large and diverse set of listening histories. It also includes artist metadata such as genre and tags, allowing for more personalized recommendations. However, the dataset may require some preprocessing to remove noise and outliers.

4. Yelp

Yelp is a dataset containing over 5 million reviews from Yelp users. The reviews cover a wide range of businesses, including restaurants, bars, and hotels. The dataset also includes business metadata such as category, location, and rating.

This dataset is useful for recommender systems that operate in the hospitality domain. It provides a large and diverse set of reviews and businesses, allowing for more accurate recommendations. However, the dataset is quite large and may require significant processing power and storage.

5. Jester

Jester is a dataset containing over 4 million ratings from 73,421 users. The ratings represent the user's opinion on a joke, with ratings ranging from -10 to 10. The dataset also includes joke metadata such as category and text.

This dataset is useful for recommender systems that operate in the humor domain. It provides a large and diverse set of ratings and jokes, allowing for more personalized recommendations. However, the dataset may require some preprocessing to remove noise and outliers.

Conclusion

In conclusion, pre-labeled datasets are a great way to jumpstart your machine learning project. The top 5 pre-labeled datasets for recommender systems are MovieLens, Amazon Reviews, Last.fm, Yelp, and Jester. Each dataset provides a unique set of data and metadata, allowing for more accurate and personalized recommendations.
