Unstructured and complex documents user guide

Last updated Jul 2, 2025

Overview

This section outlines the end-to-end process of building generative extraction models for unstructured and complex documents.

Building high-performing models is an iterative process that requires continuous prompt engineering and output validation.

The model building process

  1. Upload a sample of representative documents for the use case:
    • Identify what data points (fields) you want to extract and how they relate to each other (field groups).
    • Provide overall extraction instructions.
    • Create the corresponding extraction schema and provide field group and field instructions.
  2. Validate and improve extractions:
    • Review the initial predictions, and notice how well they are performing.
    • Modify the prompt instructions and test the impact on the performance of the model.
    • Confirm or correct extractions to gather ground truth for performance evaluation.
