Dataviewer overview

The dataviewer is the primary canvas for data exploration and supervision. You will use the dataviewer throughout Snorkel Flow, from verifying your uploaded data to annotating it with labels and developing models. Use the dataviewer to:

  • View your data in different formats, individual and aggregate.
  • Filter and sort your data.
  • Compare metadata, including ground truths, model predictions, LF votes, and more.
  • Edit ground truths.
  • Slice and comment on your data.

Access the dataviewer

Because data is so central to everything you will do in SnorkelFlow, the dataviewer is available in several places throughout your application. Some of these places include:

  1. On the right hand side of your screen when you are creating an application after you have uploaded your dataset. This is outlined in the Create Application section.
  2. On the right hand side of your screen in the Application Studio after creating an application. This is located below the search bar for creating labeling functions (LFs) and shown in the screenshot below.
  3. In the center of your screen when annotating documents.

Dataviewer feature reference

Different features will be available in each place the dataviewer is seen and based on the application type, but there is significant commonality between them. These features are outlined below.
