Multi-lingual and -modal Applications in the Semantic Web: the example of Ambient Assisted Living

Abstract

Applications of the Semantic Web (SW) are often related only to written text, neglecting other interaction modalities and a large portion of multimedia content that is available on the Web today. Processing and analysis of speech, hand and body gestures, gaze, and haptics have been the focus of research in human-human interactions and have started to gain ground in human-computer interaction in the last years. Web 4.0 or Intelligent Web, which follows Web 3.0, takes these modalities into account. This paper examines challenges that we currently face in developing multi-lingual and -modal applications and focuses on some current and future Web application domains, particularly on Ambient Assisted Living.
