prediction program that predicts from the user's behavior statement result events, prediction apparatus and method

摘要

PROBLEM TO BE SOLVED: To provide a prediction program, a prediction apparatus and a method for predicting a result event that may occur in future because of a habit of a user, caused by an irregular action event with respect to an ordinary action event of the user described in a sentence.SOLUTION: A prediction apparatus comprises habit event extraction means which extracts a habit event from a group of sentences described with the passage of time, havit distribution analysis means which detects a generation frequency of the habit event at every predetermined unit time, a reference habit distribution storage means which stores therein a generation frequency to be reference in each of habit events, correlation calculation means which calculates a correlation by comparing the generation frequency of the habit event at every predetermined unit time with the generation frequency of the reference habit event at every predetermined unit time, and irregular habit determination means in which, if the correlation is low to be less than or equal to a predetermined threshold value, a group of these habit events is outputted as an irregular habit event. Therefore, a result event that may occur in future is predicted.
