Abstract
Techniques to validate data in document capture are disclosed. An indication is received that a validation rule associated with two or more dependent fields in a data entry form comprising data values extracted from a multi-page document has failed. Ahuman validation interface is provided that enables an operator to view the affected dependent fields and for each an associated document image portion from which a corresponding data value was extracted, including by providing automated navigation to and display of the affected dependent fields.
Claims21
A method of validating data, comprising:
- extracting data values from digital content that is generated by recognizing characters or marks from a multi-page document;
- generating a data entry form comprising the data values extracted from the digital content;
- receiving an indication that one or more validation rules associated with two or more dependent fields in the data entry form comprising the data values extracted from the digital content has failed;
- providing a human validation interface that enables an operator to view the affected dependent fields and for each an associated document image portion from which a corresponding data value was extracted, including by providing automated navigation to and display of the affected dependent fields;
- receiving operator input that changes a data value of one or more of the affected dependent fields, and in response to the operator input, re-evaluating a first validation rule of the one or more validation rules;
- and
- re-evaluating a second validation rule of the one or more validation rules affected by the changes to the data value of said one or more of the affected dependent fields.
A document capture system, comprising:
- a display device;
- and
- a processor coupled to the display device and configured to:
- extract data values from digital content that is generated by recognizing characters or marks from a multi-page document;
- generate a data entry form comprising the data values extracted from the digital content;
- receive an indication that one or more validation rules associated with two or more dependent fields in the data entry form comprising the data values extracted from the digital content has failed;
- provide via the display device a human validation interface that enables an operator to view the affected dependent fields and for each an associated document image portion from which a corresponding data value was extracted, including by providing automated navigation to and display of the affected dependent fields;
- receive operator input that changes a data value of one or more of the affected dependent fields, and in response to the operator input, re-evaluate a first validation rule of the one or more validation rules;
- and
- re-evaluate a second validation rule of the one or more validation rules affected by the changes to the data value of said one or more of the affected dependent fields.
A computer program product to validate data, the computer program product being embodied in a tangible computer readable storage medium and comprising computer instructions for:
- extracting data values from digital content that is generated by recognizing characters or marks from a multi-page document;
- generating a data entry form comprising the data values extracted from the digital content;
- receiving an indication that one or more validation rules associated with two or more dependent fields in the data entry form comprising the data values extracted from the digital content has failed;
- providing a human validation interface that enables an operator to view the affected dependent fields and for each an associated document image portion from which a corresponding data value was extracted, including by providing automated navigation to and display of the affected dependent fields;
- receiving operator input that changes a data value of one or more of the affected dependent fields, and in response to the operator input, re-evaluating a first validation rule of the one or more validation rules;
- and
- re-evaluating a second validation rule of the one or more validation rules affected by the changes to the data value of said one or more of the affected dependent fields.
