Document Type and Number:
Japanese Patent JP5615857
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To predict a change in a user's preference.SOLUTION: An analysis device comprises: an extraction unit; a calculation unit; and a prediction unit. The extraction unit extracts interest information about a field in which a user is interested from user attribute information about the user of a user terminal or history information of which contents transmitted/received by the user terminal, and also extracts flow information indicating a relation between user terminals which transmits/receives the contents. The calculation unit calculates a transmission probability that relevant contents related to the contents received by the user terminal is transmitted from the user terminal to the other user terminal for each user terminal on the basis of the flow information. The prediction unit predicts a propagation probability that relevant contents of predetermined contents propagate to a predetermined user terminal on the basis of the transmission probability, and also predicts an interest degree of the user for the relevant contents on the basis of interest information of the user of the predetermined user terminal.
