Purpose
The Affinda platform automates the splitting and classification of documents. However, user review may be required to validate the model outputs. This tutorial will walk you through how to validate the splitting and classification of your documents in the Affinda Platform.If you’re a new user of the Affinda platform, we recommend viewing the Getting Started with the Affinda Platform tutorial first to get familiar with our app.
- Model improvement: Confirming documents when the data is correct will improve model performance over time by adding the documents to ‘model memory’
- Ongoing document processing: ‘Human in the loop’ review of documents processed as part of general processes
Definitions
Firstly, let’s get across what splitting and classification mean in your automated document workflow.Splitting
Splitting in Affinda refers to the platform’s ability to identify individual documents in a multi-document file. Our models will split these into individual files. This allows them to be classified and sent to the correct extraction model.
Classification
Classification is Affinda’s ability to identify what type of document it has received. This is beneficial in two ways:
- It gives you visibility on the type of documents you’ve received
- It allows these documents to be sent to the correct workflow and extraction model
How to validate document splitting and classification
1
Open the document for review in the Affinda app
Start by opening the Document Validation Interface for a document you want to review.
2
Validate Splitting

- The purple scissors icon will appear next to the document’s name on the right-hand panel
- The “Edit Pages” button in the top right corner will be blue.

Validate Classification
In Edit Pages Interface:
If you are already checking the splitting of documents, you can also check the classification in the Splitting Interface. You can see how the model has classified each document by the label next to the document’s filename. Change the classification by using the drop-down menu. Make sure you click “Apply Changes” to save changes.In Document Validation Interface:
If you are checking individual documents in the Document Validation Interface, you can see the classification the model has predicted in the top right corner. You can change the classification by using the drop-down menu.Changing the classification of a document will reparse it as it gets sent to the correct model for extraction.


For Admins: If the appropriate classification isn’t available in your Workspace, select ‘Remove Classification’. This will allow Admins to either create a new Document Type or add an existing one to the Workspace and apply it.
