Abstract
The present invention provides a dialog system, a dialog execution method and a computer program which are capable of easily updating input information and output information of a dialog scenario and easily changing a plurality of modalities by using a general-purpose dialog scenario. In a dialog system that receives information from outside, controls the pursuit of dialog along the stored dialog scenario and outputs information along the dialog scenario to the outside, a dialog scenario written by using information for identifying the meaning of words/phrases used in the input information and the output information is stored, one or a plurality of words/phrases are stored in association with information for identifying the meaning of words/phrases, input information is analyzed, a corresponding word/phrase is extracted based on the derived information for identifying the meaning of words/phrases, and output information along a dialog scenario stored, based on the extracted word/phrase is outputted.
