Navigation system with rule based point of interest classification mechanism and method of operation thereof

A method of operation of a navigation system comprising:

• generating a point of interest term from a categorized point of interest;
• calculating a position factor based on the point of interest term generated from a brand name or a standard industry code description of the categorized point of interest;
• calculating a term frequency based on a number of times the point of interest term appears within a category identifier;
• weighing the term frequency based on a number of times the categorized point of interest appears within the category identifier and the position factor;
• generating a term score for the point of interest term in the categorized point of interest based on the category identifier and the term frequency;
• generating a statistical rule based on the point of interest term, the term score, and the category identifier;
• generating the point of interest term from an uncategorized point of interest;
• applying the statistical rule to the point of interest term to generate a category score for the point of interest term from the uncategorized point of interest;
• 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 from the uncategorized point of interest;
• generating the category identifier for the uncategorized point of interest based on the normalized category score being highly ranked for displaying on a device;
• combining the category identifier with the uncategorized point of interest to create the categorized point of interest;
• transmitting the categorized point of interest;
• and
• receiving and storing the categorized point of interest.

A navigation system comprising:

• a control unit including a processor for:
• 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 a point of interest term from the brand name and the standard industry code description associated with an uncategorized point of interest;
• applying a statistical rule 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 matching between the point of interest term from the categorized point of interest and the point of interest term from the uncategorized point of interest;
• generating a category identifier for the uncategorized point of interest;
• and
• a communication unit including microelectronic, coupled to the control unit, for transmitting the category identifier for display on a device.

The system as claimed in claim wherein the control unit is for:

• combining the category identifier with the uncategorized point of interest to create the categorized point of interest;
• transmitting the categorized point of interest;
• receiving and storing the categorized point of interest;
• generating the point of interest term from the brand name and the standard industry code description associated with the categorized point of interest;
• calculating a term frequency based on a number of times the point of interest term appears within the category identifier;
• weighing the term frequency based on a number of times the point of interest term appears within the category identifier;
• generating a term score for the point of interest term based on the category identifier and the term frequency;
• and
• generating the statistical rule based on the point of interest term, the term score, and the category identifier.
