Dictionary
The Dictionary Rule can be applied to any type of extracted data and **** provides a means to perform a lookup of an expected word. The user can provide a list of expected words for a field, and using the specified Lookup Method, the closest match is used to override the value of the Parameter.
For example, if a form contains a field for a US State, then the comprehensive list of all 50 states can be supplied to the Dictionary, and the best match for what was written on the form, will be returned as the value of the field. In this case, the Dictionary can be used to correct the spelling of the expected US State.
The Lookup Method can be selected from the Lookup Method dropdown box.
