“…LectureLounge [24] is a research platform and a system to automatically and non-invasively capture, analyze, annotate, index, archive and publish live presentations. MOM (Multimedia Ontology Manager) [2] is a complete system that allows the creation of multimedia ontologies, supports automatic annotation and the creation of extended text (and audio) commentaries of video sequences, and permits complex queries by reasoning over the ontology.…”

The number of digital lecture video recordings has increased dramatically since recording technology became easier to use. The accessibility and ability to search within this large archive are limited and difficult. Manual annotation is time-consuming and therefore useless. A promising approach is based on using the audio layer of a lecture recording to obtain semantic information about the lecture's contents. The speech transcript and the words from the power point slides are sufficient to generate semantic metadata serialized in an OWL file. Two annotation methods are discussed, evaluated and compared to each other and to a perfectly annotated OWL file, as well as to an annotation based on a corrected transcript of the lecture.

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 a semantic annotation for multimedia resources, i.e., recorded university lectures. Speech recognition is applied to create a tentative 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.

“…Although the use of high definition video in online lecturing seems and actually is promising, it unfortunately is quite expansive nowadays [5]. Therefore, it is necessary to minimize the costs related to video lecture production [6], what is crucial for web-based distance education [7].…”
