Navigation system with single pass clustering based template generation mechanism and method of operation thereof

A method of operation of a document clustering system comprising:

• generating formatting sequences of documents;
• selecting a user-defined percentile representing reciprocal fraction of an expected number of clusters;
• calculating a threshold value for a first cluster with the threshold value to be equal to the user-defined percentile of a first normalized distribution of sample comparison values between the first cluster and formatting sequence samples from the formatting sequences, the first cluster is from the clusters;
• computing an associated comparison value between a first formatting sequence from the formatting sequences and the first cluster;
• grouping the first formatting sequence with the first cluster when the associated comparison value exceeds the threshold value for the first cluster;
• identifying a template matched with the first cluster;
• generating a point-of-interest page related to a point of interest from the documents using the template;
• and
• generating a travel route for a point of interest from the point-of-interest page for displaying on a device.

A navigation system comprising:

• an extraction module, for extracting with a control unit navigation-related web documents having a point of interest;
• a feature generation module, coupled to the extraction module, for generating formatting sequences of the navigation-related web documents;
• a systems setting module for selecting a user-defined percentile representing reciprocal fraction of an expected number of clusters;
• a threshold generator module, coupled to the systems setting module, the document processing module, and the clusters module, for calculating a threshold value for a first cluster with the threshold value to be equal to the user-defined percentile of a first normalized distribution of sample comparison values between the first cluster and formatting sequence samples from the formatting sequences, the first cluster is from the clusters;
• a comparison module, coupled to the feature generation module, and the threshold generator module, for computing an associated comparison value for computing an associated comparison value between a first formatting sequence from the formatting sequences and the first cluster;
• a grouping module, coupled to the comparison module, the document processing module, and the threshold generator module, for grouping the first formatting sequence with the first cluster when the associated comparison value exceeds the threshold value for the first cluster;
• and
• a route generation module, coupled to the grouping module, for generating a travel route for the point of interest related to the first cluster for displaying on a device.
