Posted sentence search system, posted sentence search apparatus, posted sentence search method, and computer program

摘要

PROBLEM TO BE SOLVED: To provide a submission sentence search system, submission sentence search device, submission sentence search method, and computer program that are able to appropriately search for only a submission sentence in which information necessary for a user is submitted.SOLUTION: If a guide route was set at a communication terminal 7, the communication terminal 7 transmits a browsing request for a submission sentence to a submission sentence search server 3. The submission sentence search server 3 having received the browsing request obtains an approach crossroad that is a road crossing the guide route, and allows a vehicle travelling the guide route to enter from the guide route. If the submission sentence search server 3 has determined there is a congestion factor facility, a facility that will be a factor to cause congestion on the periphery of the approach crossroad, it sets combination of "a name of the approach crossroad" and "congestion" or combination of "a name of an intersection of the guide route and the approach crossroad" and "congestion" to a search word, and searches for a submission sentence including the set search word among submission sentences submitted on a computer network.
