Extract Data from Custom Forms (Beta)
The custom form solution allows the users to specify what information they want to extract from their custom forms. The expected entity names are defined in a form template in JSON format, and for each entity, the user can provide its key variations to the best of one’s knowledge. The key variations are not necessarily a complete list, but the more variations are provided, the better our ML model can understand the concept of this entity. For instance, if the user wants to extract the date of birth from forms, he/she can define an entity named
date of birth, and provide its key variations in a list like
["date of birth", "birthday", "DOB", "birth date"].
The custom form solution automatically detects all the tables, recognize the texts in cells and infer the location, row and column number of each table cell. Set
AutomaticallyRecognizeTables in the form template to "true" to enable this function.
Here's an example of a form template that extracts the date of birth and last name, and detect tables.
When you call the API, send in the form as an image or PDF, set
formTemplate to the path of form template JSON file, and specify the
tabulatev2 modelId. The JSON response contains entity-value pairs for each field in the form.
