NAVIGATION SYSTEM WITH POINT OF INTEREST CLASSIFICATION MECHANISM AND METHOD OF OPERATION THEREOF
First Claim
1. A method of operation of a navigation system comprising:
- generating a training data from a randomly sampled uncategorized point of interest;
generating a trained classifier model by training a classifier model using the training data;
generating a category identifier, a confidence score, or a combination thereof for an uncategorized point of interest using the trained classifier model;
generating a categorized point of interest by assigning the category identifier to the uncategorized point of interest;
calculating a weighted confidence score based on a weighted F-measure for the category identifier, a pair of the category identifier and the confidence score; and
consolidating the categorized point of interest based on the weighted confidence score for the category identifier being meeting or exceeding a threshold for displaying on a device.

Abstract
A method of operation of a navigation system includes: generating a training data from a randomly sampled uncategorized point of interest; generating a trained classifier model by training a classifier model using the training data; generating a category identifier, a confidence score, or a combination thereof for an uncategorized point of interest using the trained classifier model; generating a categorized point of interest by assigning the category identifier to the uncategorized point of interest; calculating a weighted confidence score based on a weighted F-measure for the category identifier, a pair of the category identifier and the confidence score; and consolidating the categorized point of interest based on the weighted confidence score for the category identifier being meeting or exceeding a threshold for displaying on a device.

6. A method of operation of a navigation system comprising:
-
generating a training data from a randomly sampled uncategorized point of interest; generating a trained classifier model by training a classifier model using the training data; generating a category identifier, a confidence score, or a combination thereof for an uncategorized point of interest using the trained classifier model; generating a categorized point of interest by assigning the category identifier to the uncategorized point of interest; calculating a weighted confidence score based on a weighted F-measure for the category identifier, a pair of the category identifier and the confidence score; consolidating the categorized point of interest based on the weighted confidence score for the category identifier being meeting or exceeding a threshold for displaying on a device; and processing mutually exclusive category identifiers for the categorized point of interest by eliminating an incorrect category identifier. - View Dependent Claims (7, 8, 9, 10)

11. A navigation system comprising:
-
an active learning module for generating a training data from a randomly sampled uncategorized point of interest; a model training module, coupled to the active learning module, for generating a trained classifier model by training a classifier model using the training data; a classification module, coupled to the model training module, for generating a category identifier, a confidence score, or a combination thereof for an uncategorized point of interest and generating a categorized point of interest with the trained classifier model; and a consolidation module, coupled to the classification module, for calculating a weighted confidence score based on a weighted F-measure for the category identifier, a pair of the category identifier and the confidence score and consolidating the categorized point of interest based on the weighted confidence score for the category identifier being meeting or exceeding a threshold for displaying on a device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
