The method of claim 1 , wherein the providing the summary providing interface comprises providing the summary providing interface for outputting the summary of the predetermined range of the conversation texts within the chat room when a touch-related operation signal among scrolling operation signals including a touch and drag operation for reviewing the past conversation text is received from the user within the user's chat room including the conversation participants.
8. The method of claim 1 , wherein the providing the summary providing interface comprises providing an audio summary providing interface for outputting an audio summary of the predetermined range of the conversation texts within the chat room when the operation signal for reviewing the past conversation text is received from the user within the user's chat room including the conversation participants.
9. The method of claim 8 , further comprising generating an audio summary obtained by converting the summary into a sound in response to selection reception by the audio summary providing interface.
10. The method of claim 1 , wherein the determining the keywords comprises:
decomposing the collected conversation texts into morphological units, and extracting at least one noun, at least one interrogative pronoun, and at least one word indicating a tense; and
determining the at least one noun as the keyword, or extracting a word corresponding to an answer to the interrogative pronoun from the collected conversation texts to determine the extracted word as the keyword, or determining the word indicating the tense as the keyword.
11. A device for generating a summary of conversation contents, the device compn sing:
a collecting unit configured to collect conversation texts input by a plurality of conversation participants in a chat room;
a providing unit configured to provide a summary providing interface for outputting a summary of a predetermined range of the conversation texts within the chat room when an operation signal for reviewing a past conversation text is received from the user within a user's chat room including the conversation participants;
