Purpose of this paperThis survey aims at studying and analyzing current techniques and methods for context-aware Web service systems, discussing future trends and proposing further steps on making Web services systems being context-aware.Design/methodology/approach We analyzed and compared existing context-aware Web servicebased systems based on techniques they support, such as context information modeling, context sensing, distribution, security and privacy, and adaptation techniques. Existing systems are also examined in terms of application domains, system type, mobility support, multi-organization support and level of Web services implementation. FindingsSupporting context-aware Web service-based systems is increasing. It is hard to find a truly context-aware Web service-based system that is interoperable and secure, and operates on multiorganizational environments. Various issues, such as distributed context management, context-aware service modeling and engineering, context reasoning and quality of context, security and privacy issues have not been well addressed. Research limitations/implications (if applicable)The number of systems analyzed is limited. Furthermore, the survey is based on published papers. Therefore, up-to-date information and development might not be taken into account.What is original/value of paper Existing surveys do not focus on context-awareness techniques for Web services. This paper helps to understand the state of the art in context-aware techniques for Web services that can be employed in the future of services which is built around, amongst other, mobile devices, Web services, and pervasive environments.A previous version of this paper was published, as an invited paper, in the International Journal of Web Information Systems, 5(

Bringing context-aware access to the web through spoken interaction

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.
