Information presenting method, information presenting device, and information presenting program

An information presentation apparatus comprising:

• a storage unit configured to store rainfall information including a predetermined index value relating to past rainfall and a corresponding date-time and damage information including details of damage that occurred due to past rainfall and a corresponding date-time;
• an acquisition unit configured to acquire a spot value and a forecast value of current precipitation;
• a computation unit configured to compute an index value relating to current rainfall, using the acquired spot value and forecast value;
• a specification unit configured to specify, with reference to the rainfall information, a date-time of the index value relating to past rainfall whose similarity to the computed index value relating to current rainfall is not less than a predetermined threshold value;
• and a presentation unit configured to present, with reference to the damage information, details of damage that occurred in a period whose difference from the specified date-time is in a predetermined range.

A non-transitory computer readable medium including an information presentation program for causing a computer to execute:

• acquiring a spot value and a forecast value of current precipitation;
• computing an index value relating to current rainfall, using the acquired spot value and forecast value;
• specifying, with reference to rainfall information including a predetermined index value relating to past rainfall and a corresponding date-time, a date-time of the index value relating to past rainfall whose similarity to the computed index value relating to current rainfall is not less than a predetermined threshold value;
• and presenting, with reference to damage information including details of damage that occurred due to past rainfall and a corresponding date-time, details of damage that occurred in a period whose difference from the specified date-time is in a predetermined range.
