Patent ID: 8693842

Claim:
A system for enriching audio/video recordings, comprising: an electronic memory storing audio/video data corresponding to a presentation and annotation data received from a plurality of attendee computers or smart devices, the annotation data comprising notes taken electronically by attendees of the presentation corresponding to the audio/video data; at least one processor operatively coupled with the electronic memory; a data fusion component implemented using the at least one processor and operative to synchronize and merge the annotation data; wherein the data fusion component is operative to synchronize and merge the annotation data to form a time x term matrix including: a plurality of rows corresponding to temporal time ranges of the audio/video data; a plurality of columns corresponding to terms from the annotation data; and a plurality of matrix entries including integer values representing the number of occurrences of the corresponding term within the corresponding temporal time range; a text data mining component implemented using the at least one processor and operative to identify key message data including a plurality of key messages from the synchronized and merged annotation data and to identify a plurality of temporal segments of the audio/video data and corresponding segment data from the synchronized and merged annotation data according to the time x term matrix; and an association component implemented using the at least one processor and operative to associate the segment data corresponding to each identified temporal segment of the audio/video data with a specific time interval in the audio/video data, and to associate key message data for each identified key message with a specific time point in the audio/video data; the at least one processor configured to store an enriched audio/video recording in the electronic memory, including all or a portion of the audio/video data, the segment data, and the key message data.
