A method of identifying one or more concepts in a multimedia file includes separating text derived from the multimedia file into sub-portions, extracting features from the text of the sub-portions, and identifying concept clusters for the sub-portions based on the extracted features. The method further includes associating each of the sub-portions with the one or more concepts presented in the sub-portions of text based on the identified concept clusters and presenting, via a user interface, one or more portions of the multimedia file, where the portions of the multimedia file are generated based on the one or more concepts presented in each of the sub-portions of text of the multimedia file.
