Abstract
The number of digital video recordings has increased dramatically. The idea of recording lectures, speeches, and other academic events is not new. But, the accessibility and traceability of its content for further use is rather limited. Searching multimedia data, in particular audiovisual data, is still a challenging task to overcome. We describe and evaluate a new approach to generate asemantic annotation for multimedia resources, i.e., recorded university lectures. Speech recognition is applied to create atentative and deficient transliteration of the video recordings. We show that the imperfect transliteration is sufficient to generate semantic metadata serialized in an OWL file. The semantic annotation process based on textual material and deficient transliterations of lecture recordings are discussed and evaluated.
