Navigation system with point of interest harvesting mechanism and method of operation thereof

A method of operation of a navigation system comprising:

• generating an extraction job including a crawl task based on a location of a point of interest and a web form type of a website for harvesting the point of interest from the website;
• receiving a heartbeat and a node load from a distributed cache for determining when a client device is available to execute the extraction job;
• generating an assignment schedule of the extraction job based on the heartbeat and the node load for distributing the extraction job to the client device to retrieve a location-based field;
• and
• receiving the location-based field associated with the point of interest for displaying on a monitor device.

A navigation system comprising:

• a job generation module for generating an extraction job including a crawl task based on a location of a point of interest and a web form type of a website for harvesting the point of interest from the website;
• a cache communication module, coupled to the job generation module, for receiving a heartbeat from a distributed cache for determining when a client device is available to execute the extraction job;
• a job distribution module, coupled to the cache communication module, for generating an assignment schedule of the extraction job based on the heartbeat for distributing the extraction job to the client device to retrieve a location-based field;
• and
• a compiler module, coupled to the job distribution module, for receiving the location-based field associated with the point of interest for displaying on a monitor device.
