Ask data lenses enable you to refine the way a user's natural language query is interpreted, based on the specific audience they belong to. For instance, you might make one lens for medical staff at a hospital, and another for administrative staff. A lens allows you to define synonyms to associate key words with common terms used for them. For instance, "SF" for "San Francisco", or "Rx" for "prescription". You can also configure recommended visualizations for each lens.
Using the Tableau REST API, you can:
- Create a lens and configure its properties
- Delete a lens
- Import an existing lens
- Get a list of lenses on a site or the details of a specified lens
