Abstract

A display device to display content, identify a chat message input by a user while the content is displayed, change the identified chat message into an abbreviated message having a meaning identical or similar to the identified chat message, based on context information associated with the content being displayed, and transmit the abbreviated message to a server enabled to provide a chatbot response.

First claim

What is claimed is:

1 . A display device, comprising:
a display; a transceiver, memory to store at least one program; and at least one processor, electrically connectable to the memory, and including a processing circuit to execute at least one instruction of the at least one program while connected to the memory, wherein at least one processor, individually or in combination, is configured to:
control the display to display content;
identify a chat message input by a user while the content is displayed;
change the identified chat message into an abbreviated message having a meaning identical or similar to the identified chat message, based on context information associated with the content being displayed; and
control the transceiver to transmit the abbreviated message to a server enabled to provide a chatbot response.

2 . The display device of claim 1 , wherein the abbreviated message includes a number of tokens smaller than a number of tokens of the identified chat message.

3 . The display device of claim 1 , wherein at least one processor, individually or in combination, is configured to:
change a first text included in the identified chat message into a second text including a number of tokens smaller than a number of tokens of the first text based on a language model, and use a message including the second text as the abbreviated message.

4 . The display device of claim 1 , wherein at least one processor, individually or in combination, is configured to:
detect a language of the identified chat message based on a language model; count a first token number which is a number of tokens of the identified chat message; translate the identified chat message into a language different from the detected language; count a second token number which is a number of tokens of the translated chat message; and use the translated chat message as the abbreviated message in response to the second token number being smaller than the first token number.

5 . The display device of claim 1 , wherein at least one processor, individually or in combination, is configured to:
detect a language of the identified chat message based on a language model; count a first token number which is a number of tokens of the identified chat message; determine a second token number smaller than the first token number; translate the identified chat message into a language different from the detected language based on the determined second token number; and use the translated chat message as the abbreviated message.

6 . The display device of claim 1 , wherein at least one processor, individually or in combination, is configured to:
identify an emoticon included in the identified chat message; obtain a name of the emoticon based on a language model; identify a meaning of the emoticon based on the obtained name and generates a first text indicating the identified meaning; generate a second text having a number of tokens smaller than a number of tokens of the first text by abbreviating the first text based on the context information; and use a message including the second text as the abbreviated message.

7 . The display device of claim 1 , wherein the context information is generated based on meta information, and
wherein the meta information includes at least one of broadcast time information, broadcast channel information, a broadcast program title, a broadcast program description, a broadcast program genre, broadcast program cast information, broadcast program staff information, or broadcast program screen information obtained based on an electronic program guide (EPG).

8 . The display device of claim 1 , wherein the context information is generated based on meta information, and
wherein the meta information includes at least one of information about a person or an object appearing in the content or background information about the content obtained by screen analysis of the display device, voice or sound information obtained by audio analysis of the display device, text information obtained from a screen of the content by a text detection operation, information about one or more chat participants including the user, or conversation history information about the one or more chat participants.

9 . The display device of claim 7 , wherein at least one processor, individually or in combination, is configured to:
change the meta information to abbreviated information having a similar meaning to the meta information, and control the transceiver to transmit the abbreviated information to the server, and wherein the abbreviated information includes a number of tokens smaller than a number of tokens of the meta information.

10 . The display device of claim 1 , wherein at least one processor, individually or in combination, is configured to:
receive a response message to the abbreviated message from the server through the transceiver; and control the display to display the received response message as the chatbot response.

11 . A method for providing a chat service by a display device, the method comprising:
displaying content; identifying a chat message input by a user while the content is displayed; changing the identified chat message into an abbreviated message having a meaning identical or similar to the identified chat message, based on context information associated with the content being displayed; and transmitting the abbreviated message to a server enabled to provide a chatbot response.

12 . The method of claim 11 , wherein the abbreviated message includes a number of tokens smaller than a number of tokens of the identified chat message.

13 . The method of claim 11 , wherein the changing into the abbreviated message comprises changing a first text included in the identified chat message into a second text including a number of tokens smaller than the first text, based on a language model, and using a message including the second text as the abbreviated message.

14 . The method of claim 11 , wherein changing into the abbreviated message comprises:
detecting a language of the identified chat message based on a language model; counting a first token number which is a number of tokens of the identified chat message; translating the identified chat message into a language different from the detected language; counting a second token number which is a number of tokens of the translated chat message; and using the translated chat message as the abbreviated message in response to the second token number being smaller than the first token number.

15 . The method of claim 11 , wherein changing into the abbreviated message comprises:
detecting a language of the identified chat message based on a language model; counting a first token number which is a number of tokens of the identified chat message; determining a second token number smaller than the first token number; translating the identified chat message into a language different from the detected language based on the determined second token number; and using the translated chat message as the abbreviated message.

16 . The method of claim 11 , wherein changing into the abbreviated message comprises:
identifying an emoticon included in the identified chat message; obtaining a name of the emoticon based on a language model; identifying a meaning of the emoticon based on the obtained name and generating a first text indicating the identified meaning; generating a second text having a number of tokens smaller than a number of tokens of the first text by abbreviating the first text based
