Form Data Extraction Using Nuance

The NUANCE_EXTRACTION_PLUGIN is part of the Extraction module. You can use the NUANCE_EXTRACTION_PLUGIN to extract:

• Text data
• Checkbox data
• OCR form data
• Hand-written data
• Barcode data

You can also use the NUANCE_EXTRACTION_PLUGIN to extract data in multiple languages. Data extraction through Nuance happens with the help of template files (*.tlz). These template files are created using the Nuance Form Template Editor application installed on Windows systems.

Note: Only non-cursive handwritten extraction is supported.

Installing Nuance Form Template Editor

The Nuance Form Template Editor executable is packaged with Ephesoft Linux Installer and can be located at Application/native/Nuance.
User need to install the Nuance Form Template Editor application on a Windows system and utilize the template created through this editor while using the NUANCE_EXTRACTION_PLUGIN in a Linux environment
