Concurrently, initiatives which focus on the accessibility and regulation of multimedia resources are becoming ever greater in number. Accessibility may be achieved, among other alternatives, by means of the subtitling and audio description of multimedia contents. This paper presents a platform which enables the SA of multimedia content when the subtitling and audio description tasks are being carried out.text/plainapplication/pdfeng© IEEESemantic annotationSubtitlingAudio descriptionAccessible contentsOntologiesresearch articleInformática10.1109/MMUL.2010.43open access16225IEEE Multimedia18
