Document Type and Number:

Japanese Patent JP6653499

Kind Code:

B2

Abstract:

[Object] An object is to provide a future scenario generating device capable of generating a huge number of appropriate future scenarios. [Solution] A future scenario generating device 272 includes: phrase pair DB 92 storing a large number of causality phrase pairs; a causality network building device 290 building a causality network by linking, of the phrases stored in causality phrase pair DB 92, phrases connectable as causality, using as a start point a phrase forming a main part of a question received by a question input unit 280; a community detecting device 294 detecting a community in the causality network; and a future scenario generating unit 298 generating a future scenario by linking phrases connectable as causality and belonging to the same community as the phrase as the start point until a predetermined end condition is satisfied.
