1. A method of operation of a navigation system comprising:
- extracting a feature from a sample field with a manual label associated with a point of interest, the feature for locating the sample field in a document;
generating a rule based on the feature extracted to assign the manual label to a target field;
extracting the target field from the document with the manual label assigned by applying the rule to the document; and
inserting the target field associated with the point of interest to a location-based guide with a control unit for displaying the inserted target field on a device.
