Screening

Note

Only for Oracle and Exploration projects. Read more about Project modes.

Introduction

As soon as your project is initiated, you can start reviewing. Click on Review in the left menu if your project is not on the review page yet. ASReview LAB presents you a title and abstract to screen and label.

You are asked to make a decision: relevant or irrelevant?

ASReview Screening

Click on the decision of choice. A new record is presented to you. While you review the records, ASReview LAB continuously improves its understanding of your decisions, constantly updating the underlying ordering of the records.

As you keep reviewing documents and providing labels, you will probably see fewer relevant records. When to stop screening is left to you. See Progress and results for more information on progress monitoring and information on when to stop.

Note

If you are in doubt about your decision, take your time as you are the oracle. Based on your input, a new model will be trained in the background.

Screening in Exploration mode

In Exploration mode, a blue bar is displayed on top of the record. The blue bar indicates whether the record is relevant or irrelevant.

Full Text

If a column with Digital Object Identifiers (DOI) or URLs is available in the metadata of your dataset, ASReview LAB will display the DOI and URL during screening. Most of the time, DOIs point to the full-text of a publication. See datasets for more information on including DOI and URL values to your datasets.
