Hi @sebastian.andre for now there is no Boolean field feature in our roadmap because the same result can already be obtained in the way described by Alexandru Luca above on this thread. Just label the options which are selected and do not label the options which are not selected. Then the model will learn to extract only options which are selected. Like in this case: “1 unit” and “PUD”.
In the case of this image, you would need 8 String type fields. For each field the model will either return something or it will return nothing. For instance you may have a field called 1-unit. Then when this field is returned with value “1 unit” then that means this option was selected. When the field is empty, then that means the option was not selected.
The improvement which we are planning by end of April timeframe is to have multi-valued fields, which means instead of having 8 String type fields here you would have a single multi-valued String type field, which would return a list of values. In this case this list would have 2 values: [“1 unit”, “PUD”]. The Intelligent OCR framework allows for this kind of multivalued fields.
