What button does an active reviewer press to begin coding documents from the document queue in an Active Learning project?

In an Active Learning project, the button an active reviewer presses to start coding documents from the document queue is "Start Review." This action signifies that the reviewer is ready to begin evaluating and coding the documents that have been assigned. By clicking on this button, the reviewer is indicating that they are prepared to engage with the content and provide the necessary input, which is crucial for the learning model to progress effectively.

The other choices pertain to different functionalities within the Active Learning workflow. For instance, "Check Out Batch" often relates to managing batches of documents for review but does not initiate the actual coding process. "My Assigned Documents" typically refers to a list of documents that a reviewer should work on but does not commence the review itself. "Start Coding" might imply the action of coding but does not correctly reflect the first step in the typical workflow of active document review, which is to start the review process itself. Thus, "Start Review" encapsulates the primary action of an active reviewer entering the coding phase of the documents in the queue.
