Set a default model for custom composed model like prebuilt

Question

Is it possible to set a default model for a custom composed model, similar to the prebuilt-idDocument model? If you pass in a document that doesn't fall under one of the supported classifications (passport, drivers license, etc.) it will set the docType as prebuilt-idDocument. I want to do something similar for a custom composed model.

Answer 1

@Eliza Jeyakumar For a custom composed model which uses a set of extraction models under a single composed model, we cannot set a default model or model id under the composed model. It can only identify the best model under the composed model id and identifies it in the response under docType property.

However, you can use classification model to identify the type of document in input and then call its corresponding extraction model to extract content from the document. For example, the classification model identifies a document of a particular type, say type3. You can now use this information to call the trained custom extraction model of type3 to extract the content of the document.

To summarize, With the introduction of custom classification models, you can choose to use a composed model or classification model as an explicit step before analysis.
