We're introducing a new field type: Function. The first function available is Classify, which automatically categorizes your extracted data based on rules you define.
When you add a field to your schema, you can now select "Classify" from the Function section. This creates a derived field that can analyze other fields in your dataset and assign categories based on your instructions.
For example, if you're extracting job postings with a country field, you can create a "region" classification that automatically categorizes each job by geographic region.
