Event prediction device, prediction model generator and event prediction program

摘要

The learning data input unit 10 for inputting m sentences as learning data, extracting n words from the m sentences, and calculating the similarity index value calculating the similarity index value reflecting the relationship between the m sentences and the n words A classification model generating unit 14 for generating a classification model for classifying m sentences into a plurality of events based on the unit 100 and a sentence index value group comprising n similarity index values for one sentence; By applying the similarity index value calculated by the similarity index value calculation unit 100 from the sentence input by the prediction data input unit 20 to the classification model, any one of a plurality of events is predicted from the prediction target sentence A high-precision classification model is generated using a similarity index value indicating which word contributes to which sentence to what extent.
