Documents overview

When you use the toggle to switch between upload and documents view, you will get an overview of all the documents that are currently present in the production data.

This table simply gives you the list of documents and provides filter and search fields for searching for one or more documents.


You can quickly find specific documents by making use of the filtering functionality.

Filtering by "Entity Value" functions akin to a "starts with" criterion.

Example: If you filter on "Entity Value" with the term "ABC," the results will include documents where an entity value starts with "ABC," such as "ABC123" or "ABCxyz". Documents with entity values that contain "ABC" but don't start with it will be ignored, such as "123ABC" or "asdABC123".

Bulk actions

Selecting documents allows you to perform an action on multiple documents:

  • Send to training Sends the selected documents that have been processed to the training data so that your models can be enriched with production data (sending to training data happens automatically for uploads that required input from the user. Note that the annotations on these documents still have to be reviewed and a new training has to be triggered before the model is updated!)

  • Retry upload(s) You can retry the document classification or entity extraction

Document details

When you click on a document row, you can view extra details such as when it was uploaded, which steps of the pipeline were performed and what the current status is of the selected document.

Document View

By clicking "View document", you can inspect the document more closely.

Metadata document

The 'metadata' shows all the properties of the document:



  • Processing Document is being processed

  • Input required Document has been processed by Metamaze AI but requires human input to be completed

  • Processed Document has been processed

  • Failed Processing of the document failed


The document type


The language of the document which was set manually or predicted by the OCR step


The number of pages in the document


The name of the document


The unique ID of the document with handy copy button

Upload date

The date and time the document was uploaded in Metamaze


  • Copy URL Copy the URL for easy sharing with colleagues or support when you have a problem

  • Download PDF Download a PDF version of the document

  • History View all the events that happened for the document

  • Similar documents Find the most similar training documents


The first panel shows the upload with one or more documents you need to handle. Automatically the document is selected depending on which document you selected from the Uploads or documents view. You can select other documents by clicking on a row.

The following properties of the document list are shown:



Icons for the following statuses:


The position of the document in the upload


  • Page management Opens the page management screen for the upload. If you notice when processing documents that pages are wrong for a document, you can correct these in the page management screen. Afterwards, these modified documents will receive new predictions from the entity extraction model and will be queued for verification again if applicable.

  • Reject upload Rejects the whole upload. This action is only available in human validation.

Document actions

At the top of the document processing screen you have a number of buttons that help you navigate between documents and uploads.

  • Back - When in human validation, this button puts the document back in the queue. When in training or production data modules, or in tasks, it will go back to the overview of uploads, documents or tasks.

  • Upload done - This button is only available in human validation. You use this button when you have successfully finished processing all documents from an upload. The upload will then go to the next step 'output' to send the result to your system.

  • Done - When you are done with your intervention, you can mark the document as done.

  • Park - This button is only available in human intervention and in the tasks module. Use this button to park the document to handle it at a later time. A popup will be shown where you need to fill in a reason for parking, this will help you later when asking your colleagues or manager for feedback about the document. It reminds you of why you decided to put this specific document in parked.

  • Reject - This button is used if there is a problem with the document. Besides some standard errors like 'bad OCR' or 'irrelevant document' you can define your errors in the project settings, see Custom errors.


This list shows each entity defined for this document together with the number of times this entity was found in the document.


The list gives an overview of all entities with their values found in the document which have been predicted by a model or manually added by a person. An entity always has a colour but if the entity was found by the model it has a lighter transparent colour. If the entity was manually added by a person it has a darker colour.

List view

The list shows the following data:



The name of the entity


The value of the entity


The parsed value of the entity


The user who did the annotation. The value AI indicates that the annotation was predicted by the model.



The page on which the entity appears


  • Click on a row Selects the entity in the document view, giving you actions to perform on the entity

You can click a row in this list to see the value in the document. You can add additional entity values in the document by clicking the first and the last word of an entity, or by selecting it with dragging, and then selecting the correct label in the dropdown menu that will open. More info on how to perform entity annotation can be found in Annotation of training data.

Table view

The table view allows you to view the annotations in a table format. This is very handy for viewing composites in a table like format. What's more is that the icon in the top right corner allows you to customize the table:

  • Which entities to show

  • Which enrichments to show

  • Which values to show for enrichments when dealing with entries

  • The order of entities and enrichments

With these customization options, you can easily set the order of the columns and only show relevant ones when you need to compare entity values and what enrichments returned for example.

Checkbox actions

Selecting 1 or more entities through the checkboxes allows you to perform the following actions:

  • Delete annotations - Removes the selected annotations

  • Enrich annotation - Can only be used on 1 annotation at a time and allows you to link an enrichment to the entity.

You can "Shift" click to select a range of annotations to make bulk selection easier.

Document preview

The document preview allows you to see what the document looks like. It shows al the entities that were found. This view also has 2 modes:

  • Hybrid - the original document is shown

  • Formatted - the text is displayed as the OCR model has recognised it

When certain words are not readable in a display, you can always change the display. In the 2 possible views it is possible to add entities.

It is also possible to enlarge or reduce the display or to open it on a second screen.
