Boolean, categorical and string labels

The main types of labels in Sysrev are Boolean, Categorical and String:

• Boolean labels are for labels that would require a yes or no answer.
• Categorical labels can have one of a limited number of possible values. Reviewers can choose from a list, and this can be set so reviewers can choose only one or multiple answers.
• String labels are 'free text' labels. These can be constrained by number of characters or can be set to take only a certain pattern (using regular expressions).

Each label has a number of different settings including:

• whether an answer is required for review or if the label can be skipped,
• whether reviewer consensus is required (i.e., if differing answers between reviewers should be flagged as conflicts),
• whether the answer should align with the inclusion decision or not--if yes, a reviewer will be alerted to conflicts between their inclusion decision and their label answer.

There are also settings related to auto labeling, which are covered in the auto labeling section of this guide. The following video, created by CMU Libraries, demonstrates creating labels and walks through some of these settings in more detail.

NOTE: Label questions can be edited at anytime. However, for categorical labels, categories that have been used in prior labeling in the project cannot be edited or deleted. That said, new categories can be added at any time.
