WAMIS 2011 - The Seventh International Symposium on Web and Mobile Information Services (WAMIS 2011)

Advances in the Web and mobile technologies offer new and exciting services to users in various domains such as e-business, healthcare, entertainment, and scientific activities. Various organizations, academic institutions and industries are putting enormous efforts and resources in the research and development of the Web and mobile technologies through the development of new initiatives and technologies. For instance, W3C Mobile Web Initiative aims to provide mobile devices with access to the vast information available on the Web and to enable information services to be adapted to the needs of users and the characteristics of mobile devices.

With the advances in mobile technologies, Web also gets richer in its contents and usability. In addition to its widespread usability in the e-commerce, education, and media, it has established its roots in exchanging and sharing information in social communities. For example, user-generated contents in the social networks have transformed the Web into a new era or the Web2.0 - these contents comprise a wealth of information often involving multimedia data such as audio, video, pictures and blogs.

These new developments however introduce many new challenging problems to researchers. One of the major issues is to deal with the resource scarcity in mobile environment. Though mobile devices and wireless networks are improving their resources, they are still far behind the wired networks and desktop PCs in terms of bandwidth, memory, processing speed and battery powers. There are still various unresolved issues in the web and mobile services. For example, users want mobile devices to react to the changes in locations, context, contents and variation in network bandwidth while accessing Web contents.
