Abstract
A method of operation of a navigation system includes: 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 for displaying on a device.
