A unified, comprehensive and efficient recommendation library

Install Quick Start Datasets arXiv RecBole2.0 Hyper
General and extensible data structure

We design general and extensible data structures to unify the formatting and usage of various recommendation datasets.

Comprehensive benchmark models and datasets

We implement more than 100 commonly used recommendation algorithms, and provide the formatted copies of 43 recommendation datasets.

Extensive and standard evaluation protocols

We support a series of widely adopted evaluation protocols or settings for testing and comparing recommendation algorithms.

RecBole is developed based on Python and PyTorch for reproducing and developing recommendation algorithms in a unified, comprehensive and efficient framework for research purpose. It can be installed from pip, conda and source, and easy to use.
Detailed in [ Install RecBole ].

We have implemented more than 100 recommender system models, covering four common recommender system categories in RecBole and eight toolkits of RecBole2.0, including: General Recommendation, Sequential Recommendation, Context-aware Recommendation, Knowledge-based Recommendation and subpackages, which can support the basic research in recommender systems. Detailed in [ Model List ].

We design a unified and flexible data file format, and provide the support for 43 benchmark recommendation datasets. A user can apply the provided script to process the original data copy, or simply download the processed datasets by our team. Detailed in [ Dataset List ].

On the basis of RecBole, our team has continuously expanded and updated it from the perspective of data and model for different research directions, and launched eight extension toolkits in version 2.0. Until now, RecBole has a total of 11 related GitHub projects. Detailed in 【 RecBole2.0 】

RecBole is freely open to universities, teachers, students and enthusiasts in recommender system. We will provide regular maintenance and update for RecBole. Anyone who interested in our project is welcome to join us. Let us build a much more wonderful open source community of recommender system! Detailed in [ About ].
