The increasing need to access information everywhere and at any time leads us to believe that future user interfaces, through which users interact with pervasive computing systems, must address both device and modality independence. The pervasive computing paradigm sees almost every object in the everyday environment as a system able to communicate with(More)
In recent years social media are becoming ubiquitous and important for social networking and for sharing content and knowledge; they are increasingly used for professional purposes beyond personal and home use. Social networks are spreading so much that they now represent one of the most relevant and interesting social phenomena. The study presented in this(More)
Human-to-human conversation remains such a significant part of our working activities because of its naturalness. Multimodal interaction systems combine visual information with voice, gestures and other modalities to provide flexible and powerful dialogue approaches. The use of integrated multiple input modes enables users to benefit from the natural(More)
The high complexity of natural language and the huge amount of human and temporal resources necessary for producing the grammars lead several researchers in the area of Natural Language Processing to investigate various solutions for automating grammar generation and updating processes. Many algorithms for Context-Free Grammar inference have been developed(More)
Multimodal interaction represents the future of human-computer interaction. It aims at enabling users to communicate more freely and naturally with automated systems. Current approaches to multimodal dialogue systems are based on two different strategies to perform the modality fusion. The former implements the multimodal fusion at dialogue management(More)
The clinical trial has to be rigidly followed because it identifies a uniform clinical behaviour, which has to be adopted by the different physicians carrying out the test. The life cycle of the clinical trial is therefore based on a planning and definition phase, a next experimental phase connected with its diffusion to the involved centres and finally an(More)
