More efficient literature reviews, with higher quality

Announcing Deep Dynamics’ Extract: literature reviews, powered by machine learning

Accelerated Reference Screening

With Extract, reference screening is reduced with up to 85.9% of its original size. Machine learning enables to classify references (with a score) from highly relevant to not relevant. Reviewers are always in control as they decide whether to exclude or include a reference.

With Extract, the reviewer is always in control

First, screen a part of the references manually (average 43.9%), to train the software. Relevant references are prioritized. Then, check the results and classify the remaining references manually, in bulk. In this way, the reviewer is always in control. Only highly irrelevant references can be classified in bulk and no single reference is automatically excluded or classified.

Automated vs. manual screening quality compared

Reviewing with Extract, means higher quality. Human retrieval rates (recall) are 92% (Edwards et al.). With Extract, 98% recall was found (SD 2,41%). Tested on Cochrane Diagnostic Test Accuracy Reviews (Cormack et al.). Considered the most challenging to classify with software.
