“…We have also additional lines of research related to this work that includes a dialog system to our context-aware system to provide a natural and intelligent interaction of the user by means of an advanced speech-based interface [19]. And a further issue of interest for us is the inclusion of agent technology to distribute the contextual information instead of using Appear platform and finally compare results of both approachs [33].…”

a b s t r a c tKnowledge-based systems (KBS) are advanced systems for representing complex problems. Their architecture and representation formalisms are the groundwork of today's systems. The knowledge is usually derived from expertise in specific areas and has to be validated according to a different methodology than is used in conventional systems because the knowledge is symbolic. This paper describes the design, definition and evaluation of a knowledge-based system using the CommonKADS (CKADS) methodology to formally represent contextual information for the Appear platform. We also evaluate the context-aware information system from the user's point of view using a U2E system and also validate it through a simulated example in a realistic environment: an airport domain, which is a significant step towards formally building KBS applications.

“…The appropriateness of an UI of a specific mobile device depends on the facilities provided by the mobile device as well as the user's personality and the environment [Sefid‐Dashti and Habibi, ]; as such UIs can be customized according to a combination of statistical data, UCD guidelines and psychological models [Sefid‐Dashti and Habibi, ]. Some of the possible UIs are oral interfaces [Griol et al., ], augmented reality UIs [Broll et al., ; Broll et al., ] such as Near Field Communication (NFC) for touching and Visual Markers for pointing, and Conceptual Bookmarks [Henze et al., ]; in addition voice and text combinations such as Microsoft Live search [Acero et al., ] are among the more common options. This pattern improves usability and makes a compromise between response time and fully fledged UI.…”

Integration of mobile devices into a service‐oriented system involves the consideration of architectural design principles and trade‐offs among interdependent design decisions to cope with limitations of mobile devices in terms of resources available within a device and aspects of network connectivity. Mobile devices consume some services and provide others. A reference architecture (RA) that provides solutions, baseline and future insights is the priority in designing efficient mobile service oriented architecture (SOA). This paper discusses nuances of the concept of RA. The paper presents a survey of 26 mobile SOA patterns and proposes mobile SOA RA that extends Open Group SOA RA based on the catalogue of mobile SOA patterns proposed in this paper. Evaluations are made and discussed for both RA and its possible instantiation.

“…The system provides information in natural language about train services, types, schedules, and fares [15]. The information offered to inform the user is extracted from a web service developed with the information available in the web of the Spanish National Railways.…”

The web has become the largest repository of multimedia information and its convergence with telecommunications is now bringing the benefits of web technology to handheld devices. To optimize data access using these devices and provide services which meet the user needs through intelligent information retrieval, the system must sense and interpret the user environment and the communication context. In addition, natural spoken conversation with handheld devices makes possible the use of these applications in environments in which the use of GUI interfaces is not effective, provides a more natural human-computer interaction, and facilitates access to the web for people with visual or motor disabilities, allowing their integration and the elimination of barriers to Internet access. In this paper, we present an architecture for the design of context-aware systems that use speech to access web services. Our contribution focuses specifically on the use of context information to improve the effectiveness of providing web services by using a spoken dialog system for the user-system interaction. We also describe an application of our proposal to develop a context-aware railway information system, and provide a detailed evaluation of the influence of the context information in the quality of the services that are supplied.
