DEVICE FOR PREDICTING SCALE OF INFORMATION DIFFUSION, METHOD FOR PREDICTING SCALE OF INFORMATION DIFFUSION, AND PROGRAM FOR PREDICTING SCALE OF INFORMATION DIFFUSION

摘要

In order to provide an SNS or the like with a device for predicting the scale of information diffusion that will make it possible to accurately predict a number of future contributions with respect to a specific topic, a device for predicting the scale of information diffusion (10) related to the present invention is characterized in comprising: a learning text data input unit (101) for acquiring text data for learning purposes from a specific website; a node effect learning unit (102) for calculating from a number of remarks on different topics the effect on the number of remarks of each group belonging to a node that shows a single specific user for a relevant topic, and storing same as learning data; a predictive text data input unit (106) for acquiring text data for prediction purposes from a specific website after the learning data has been stored; and a unit for predicting future number of contributions (107) for predicting and outputting, from the number of remarks on different topics and the learning data, a number of contributions on a relevant topic at a specific time in the future.
