Base Claim:
1. A method of operation of a navigation system comprising: calculating a position factor based on a point of interest term generated from a brand name or a standard industry code description of a categorized point of interest; generating the point of interest term from an uncategorized point of interest; applying a statistical rule, generated based on the position factor, to the point of interest term from the uncategorized point of interest to generate a category score for the point of interest term; determining a normalized category score based on the category score and on matching the point of interest term from the categorized point of interest and the point of interest term from the uncategorized point of interest; and generating a category identifier for the uncategorized point of interest based on the normalized category score being highly ranked for displaying on a device.

Claim 5:
5. The method as claimed in claim 1 wherein determining a normalized category score includes: calculating a total category score by adding up every instance of the category score in the uncategorized point of interest for each instance of the category identifier; calculating a category weight based on the ratio between the number of instances of the point of interest term in the uncategorized point of interest and the number of instances of the point of interest term in the uncategorized point of interest with the category identifier; multiplying the category weight with the category score to obtain a weighted category score; and generating a normalized category score by dividing the weighted category score by the total category score.
