Abstract

Claims (33)

1 . A method for an association of a social network message written by a user in a social device with a related multimedia flow received by a broadcast receiver device, comprising the following in a correlation device able to communicate with the social device and the broadcast receiver device:

detecting the presence of the broadcast receiver device receiving a multimedia flow in the same location as the social device,

extracting social keywords from a social message written by the user,

requesting the broadcast receiver device for metadata about the received multimedia flow and extracting multimedia keywords from the metadata of the multimedia flow,

providing a correlation coefficient as a result of a probabilistic measure between the multimedia keywords and the social keywords,

retrieving an identifier of a social network thread associated with the multimedia flow,

if the correlation coefficient is greater than a first predefined threshold, adding the retrieved identifier to the text of the social message.

2 . A method according to claim 1 , wherein, if the correlation coefficient is greater than a second predefined threshold and below the first predefined threshold, the user is prompted for confirmation that the social message is in relation with the retrieved official identifier before adding the retrieved official identifier to the text of the social message.

3 . A method according to claim 1 , wherein social keywords are extracted from the social message written by the user as soon as the user has entered a given number of words of the social message, and the social keywords are updated for the next words written by the user.

4 . A method according to claim 1 , wherein social keywords are extracted from the social message written by the user when the user has finished writing the social message and his ready to post it.

5 . A method according to claim 1 , wherein the probabilistic measure is based on a similarity measure between the multimedia keywords and the social keywords.

6 . A method according to claim 5 , wherein the similarity measure is a cosine similarity measure.

7 . A method according to claim 1 , wherein the identifier of a social network thread is retrieved from the metadata associated with the multimedia flow.

8 . A method according to claim 1 , wherein the identifier of a social network thread is retrieved from a server by means of an identifier of the multimedia flow included in the metadata associated with the multimedia flow.

9 . A method according to claim 1 , wherein the identifier of a social network thread is retrieved from a module that has generated said identifier from the metadata associated with the broadcast multimedia flow.

10 . A method according to claim 1 , wherein the identifier of a social network thread is a hashtag.

11 . A method according to claim 1 , wherein the presence of the broadcast receiver device is detected during a device discovery process using at least one of the communication protocols among Digital Living Network Alliance protocol and Bluetooth protocol.

12 . A method according to claim 1 , wherein the broadcast receiver device and the social device are included in the same entity.

13 . A method according to claim 1 , wherein the social device and the correlation device are included in the same entity.

14 . A correlation device for an association of a social network message written by a user in a social device with a related multimedia flow received by a broadcast receiver device, the correlation device being able to communicate with the social device and the broadcast receiver device:

means for detecting the presence of the broadcast receiver device receiving a multimedia flow in the same location as the social device,

means for extracting social keywords from a social message written by the user,

means for requesting the broadcast receiver device for metadata about the received multimedia flow and extracting multimedia keywords from the metadata of the multimedia flow,

means for providing a correlation coefficient as a result of a probabilistic measure between the multimedia keywords and the social keywords,

means for retrieving an identifier of a social network thread associated with the multimedia flow,

means for adding the retrieved identifier to the text of the social message, if the correlation coefficient is greater than a first predefined threshold.

15 . A computer program capable of being implemented within a correlation device for an association of a social network message written by a user in a social device with a related multimedia flow received by a broadcast receiver device, the correlation device being able to communicate with the social device and the broadcast receiver device, said program comprising instructions which, when the program is loaded and executed within said device, carry out the following steps:

detecting the presence of the broadcast receiver device receiving a multimedia flow in the same location as the social device,

extracting social keywords from a social message written by the user,

requesting the broadcast receiver device for metadata about the received multimedia flow and extracting multimedia keywords from the metadata of the multimedia flow,

providing a correlation coefficient as a result of a probabilistic measure between the multimedia keywords and the social keywords,

retrieving an identifier of a social network thread associated with the multimedia flow,

if the correlation coefficient is greater than a first predefined threshold, adding the retrieved identifier to the text of the social message.
