Tour Miner: Mining system of tour plans from SNS: — Smelting function from travel records to tour routes —

We have been developing a system, called Tour Miner, which mines tour plans from SNS. It consists of two functions: mining and smelting. The mining function searches SNS for a given keyword and discovers travel records related to the keyword. The smelting function combines the travel records and extracts tour plans from the combination. In this paper, we elucidate the implementation of the smelting function. It first converts the travel records into a graph by process mining technique, and then gives each path of the graph as a tour route. We also illustrate its usefulness with an application example.
