Traffic-related information dictionary creating device, traffic-related information dictionary creating method, and traffic-related information dictionary creating program

A traffic-related information learning method comprising:

• acquiring, with a processor, a social network message and position information that corresponds to the social network message from a social network server, the social network message having been provided to the social network server by a social network service and stored in the social network server with the position information, the position information specifying a position at which the social network message was provided to the social network service by a user of the social network service;
• acquiring, with the processor, traffic-related information from the traffic-related information distribution server, the traffic-related information including:
• information that specifies an occurring traffic-related event;
• and
• information that specifies a location affected by the occurring traffic-related event;
• based on the acquired position information and the acquired traffic-related information, determining, with the processor, whether the position at which the social network message was provided is within the location affected by the occurring traffic-related event;
• when the position at which the social network message was provided is within the location affected by the occurring traffic-related event:
• extracting, with the processor, a phrase that expresses the traffic related event from the provided social network message;
• and
• associating, with the processor, the extracted phrase with the occurring traffic-related event;
• storing, with the processor, the associated phrase and the occurring traffic-related event in the memory;
• and
• when queried with an input traffic related event, referring to the memory and outputting, with the processor, a stored traffic-related information phrase to be used to describe the input traffic related event.

A non-transitory computer-readable storage medium storing a computer-executable traffic-related information learning program, the program comprising:

• instructions for acquiring a social network message and position information that corresponds to the social network message from a social network server, the social network message having been provided to the social network server by a social network service and stored in the social network server with the position information, the position information specifying a position at which the social network message was provided to the social network service by a user of the social network service;
• instructions for acquiring traffic-related information from the traffic-related information distribution server, the traffic-related information including:
• information that specifies an occurring traffic-related event;
• and
• information that specifies a location affected by the occurring traffic-related event;
• instructions for, based on the acquired position information and the acquired traffic-related information, determining whether the position at which the social network message was provided is within the location affected by the occurring traffic-related event;
• instructions for, when the position at which the social network message was provided is within the location affected by the occurring traffic-related event:
• extracting a phrase that expresses the traffic related event from the provided social network message;
• and
• associating a phrase included in the identified provided information with the occurring traffic-related event;
• and
• instructions for storing the associated phrase and the occurring traffic-related event in the memory;
• and
• instructions for, when queried with an input traffic related event, referring to the memory and outputting a stored traffic-related information phrase to be used to describe the input traffic related event.
