Document Type and Number:
WIPO Patent Application WO/2013/073377
Kind Code:
A1
Abstract:
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.
