Abstract
The present invention relates to automatic summarization so as to recognize entire contents of multimedia data. A method of generating summarized information according to the present invention includes: generating index information on a specific audio signal or a specific video signal among input signals; synchronizing text information extracted from the input signal or received for the input signal with the index information; and generating first summarized information by using the synchronized text information and index information.
Claims11
A method of generating summarized information, comprising:
- generating index information on a specific audio signal or a specific video signal among input signals;
- synchronizing text information extracted from the input signal or received for the input signal with the index information;
- generating first summarized information by using the synchronized text information and index information;
- and
- generating second summarized information by using additional information existing on a web for the input signal and the first summarized information,
- wherein the generating index information comprises;
- separating an input signal into an audio signal and a video signal according to a type of input signal;
- separating the audio signal into a voice signal and a non-voice signal;
- performing voice recognition on the voice signal;
- and
- extracting the text information based on an output of the voice recognition,
- wherein the synchronizing comprises;
- extracting main text information on the input signal by using the text information;
- and
- synchronizing the main text information with the index information according to a time sequence, and
- wherein the non-voice signal is based on a topic and the main text information is extracted by using a predetermined topic detection method.
