Abstract

A processor set receives data detected from sensor devices associated with an online conference session. The processor set, based on analyzing the data, determines a contribution score for each of a plurality of participants attending the online conference, which is being conducted via the video stream. The contribution score indicates a participant's level of contribution during the online conference session. The processor set controls performing of an automatic close-up of a camera view in the online conference session to a participant having a highest contribution score among the plurality of participants attending the online conference being conducted via the video stream.

Claims (34)

1 . A computer-implemented method comprising:

receiving, by a processor set, data detected from sensor devices associated with an online conference session being conducted via a video stream;

based on analyzing the data, determining, by the processor set, a contribution score for each of a plurality of participants attending the online conference session being conducted via the video stream, the contribution score indicating a participant's level of contribution during the online conference session being conducted via the video stream, the contribution score of a participant determined based on at least the participant summarizing points of the online conference session during the online conference session, overall tone of the participant during the online conference session and participant's consistency across different topics during the online conference session; and

controlling, by the processor set, performing of an automatic close-up of a camera view in the online conference session to a participant having a highest contribution score among the plurality of participants attending the online conference being conducted via the video stream.

2 . The computer-implemented method of claim 1 , wherein the data includes real-time data.

3 . The computer-implemented method of claim 1 , wherein the close-up of the camera view is automatically adjusted to another participant based on real-time determination of the contribution score.

4 . The computer-implemented method of claim 1 , wherein the close-up of the camera view is adjusted based on receiving input feedback.

5 . The computer-implemented method of claim 1 , wherein the data includes audio data and video data.

6 . The computer-implemented method of claim 1 , wherein the data is analyzed using speech recognition and natural language processing.

7 . The computer-implemented method of claim 1 , wherein the contribution score is determined based on at least one preconfigured factor.

8 . The computer-implemented method of claim 1 , wherein the contribution score is determined based on at least one preconfigured rule.

9 . The computer-implemented method of claim 1 , wherein the contribution score is determined based on a frequency of speech related to a topic of discussion.

10 . The computer-implemented method of claim 1 , wherein the contribution score is determined based on a frequency of speech.

11 . The computer-implemented method of claim 1 , wherein the contribution score is determined based on a number of spoken words.

12 . The computer-implemented method of claim 1 , defining a data structure with attributes that stores the data and associated analytics in real-time.

13 . The computer-implemented method of claim 1 , wherein the method is implemented as a plugin to an online conference platform.

14 . A computer program product comprising:

a set of one or more computer-readable storage media;

program instructions, collectively stored in the set of one or more storage media, for causing a processor set to perform the following computer operations:

receive data detected from sensor devices associated with an online conference session being conducted via a video stream;

based on analyzing the data, determine a contribution score for each of a plurality of participants attending the online conference session being conducted via the video stream, the contribution score indicating a participant's level of contribution during the online conference session being conducted via the video stream, the contribution score of a participant determined based on at least the participant summarizing points of the online conference session during the online conference session, overall tone of the participant during the online conference session and participant's consistency across different topics during the online conference session; and

control performing of an automatic close-up of a camera view in the online conference session to a participant having a highest contribution score among the plurality of participants attending the online conference being conducted via the video stream.

15 . The computer program product of claim 14 , wherein the data includes real-time data.

16 . The computer program product of claim 14 , wherein the close-up of the camera view is automatically adjusted to another participant based on real-time determination of the contribution score.

17 . The computer program product of claim 14 , wherein the close-up of the camera view is adjusted based on receiving input feedback.

18 . The computer program product of claim 14 , wherein the data includes audio data and video data.

19 . The computer program product of claim 14 , wherein the contribution score is determined based on at least one preconfigured factor.

20 . A computer system comprising:

a processor set;

a set of one or more computer-readable storage media;

program instructions, collectively stored in the set of one or more computer-readable storage media, for causing the processor set to perform the following computer operations:

receive data detected from sensor devices associated with an online conference session being conducted via the video stream;

based on analyzing the data, determine a contribution score for each of a plurality of participants attending the online conference session being conducted via the video stream, the contribution score indicating a participant's level of contribution during the online conference session being conducted via the video stream, the contribution score of a participant determined based on at least the participant summarizing points of the online conference session during the online conference session, overall tone of the participant during the online conference session and participant's consistency across different topics during the online conference session; and

control performing of an automatic close-up of a camera view in the online conference session to a participant having a highest contribution score among the plurality of participants attending the online conference being conducted via the video stream.
