About opensource

ASReview LAB is an open-source machine learning tool for screening large sets of text records. It is used for systematic reviews, meta-analyses, and other tasks that require systematic text screening. Users import datasets in formats such as CSV, RIS, and XLSX, then label records as relevant or not relevant. Its active learning models use those labeling decisions to prioritize the remaining records.

The tool also supports prior knowledge input, progress monitoring through a dashboard, and export of labeled datasets or project files. A simulation toolkit can assess model performance on fully labeled datasets. Version 3 adds automatic hiding of duplicate records during screening, with an option to include them on export. The software is licensed under Apache 2.0. Installation requires Python 3.10 or later.
