ASReview: Active learning for Systematic Reviews

Build Status Documentation Status DOI CII Best Practices

Systematic Reviews are “top of the bill” in research. The number of scientific studies is increasing exponentially in many scholarly fields. Performing a sound systematic review is a time-consuming and sometimes boring task. The ASReview software is designed to accelerate the step of screening abstracts and titles with a minimum of papers to be read by a human with no or very few false negatives.

The Active learning for Systematic Reviews (ASReview) project, publised in Nature Machine Intelligence, implements machine learning algorithms that interactively query the researcher. This way of interactive machine learning is known as Active Learning. ASReview offers support for classical learning algorithms and state-of-the-art learning algorithms like neural networks.

ASReview software implements two different modes:

  • ASReview LAB 🔮 This modus is used to perform a systematic review with interaction by the reviewer (the 'oracle' in literature on active learning). The software presents papers to the reviewer, whereafter the reviewer classifies them. See ASReview LAB.
  • Simulate 📈 The simulation modus is used to measure the performance of the active learning software on the results of fully labeled systematic reviews. To use the simulation mode, knowledge on programming and bash/Command Prompt is highly recommanded.


The ASReview software requires Python 3.6+. Detailed step-by-step instructions to install Python and ASReview are available for Windows and macOS users. The project is available on Pypi. Install the project with (Windows users might have to use the prefix python -m):

pip install asreview

Upgrade ASReview with the following command:

pip install --upgrade asreview

Instructions for usage with Docker are here.

ASReview LAB

ASReview LAB is a user-friendly interface for screening documents and experimentation with AI-aided systematic reviews. Read more about using the software in the Quick Tour.

Covid-19 plugin

Covid-19 Plugin

The ASReview team developed a plugin for researchers and doctors to facilitate the reading of literature on the Coronavirus. The plugin makes the CORD-19 dataset available in the ASReview software. A second database with studies published after December 1st 2019 is available as well (this dataset is more specific for publications on COVID-19).

Install the plugin with the command below.

pip install asreview-covid19
