Abstract

A computer executes: an extraction procedure of extracting time series data of a feature for each participant in a dialogue from time series data regarding the dialogue, a value of which is changeable according to the train of thought of the participant in the dialogue; a generation procedure of generating display data visualizing the time series data of the feature together with a video of the dialogue in synchronization with a time of the video; and a display procedure of displaying the display data. Accordingly, it is possible to ascertain a train of thought of the participant in the dialogue.

Claims (21)

1 . A dialogue replay method, comprising:

causing a computer to execute:

extracting time series data of various types of features for each participant of a plurality of participants in a dialogue from time series data regarding the dialogue, a value of which is changeable according to a train of thought of the each participant in the dialogue;

calculating a sum of the features for the plurality of participants in an identified type of the features, with the features being weighted respectively for the plurality of participants;

generating display data visualizing the time series data of the sum of the features together with a video of the dialogue in synchronization with a time of the video; and

displaying the display data.

2 . The dialogue replay method according to claim 1 , wherein

the computer executes summarizing the video based on a feature of the each participant, and

the generating the display data generates the display data visualizing the time series data of the sum of the features together with the summarized video in synchronization with a time of the summarized video.

3 . A non-transitory computer-readable storage medium storing a program causing a computer to execute the dialogue replay method according to claim 2 .

4 . A non-transitory computer-readable storage medium storing a program causing a computer to execute the dialogue replay method according to claim 1 .

5 . A dialogue replay apparatus, comprising:

a processor; and

a memory storing one or more programs, which when executed, cause the processor to execute:

extracting time series data of various types of features for each participant of a plurality of participants in a dialogue from time series data regarding the dialogue, a value of which is changeable according to a train of thought of the each participant in the dialogue;

calculating a sum of the features for the plurality of participants in an identified type of the features, with the features being weighted respectively for the plurality of participants;

generating display data visualizing the time series data of the sum of the features together with a video of the dialogue in synchronization with a time of the video; and

displaying the display data.

6 . The dialogue replay apparatus according to claim 5 , wherein

the processor is caused to execute summarizing the video based on a feature of the each participant,

wherein the generating the display data generates the display data visualizing the time series data of the sum of the features together with the summarized video in synchronization with a time of the summarized video.
