An example of such systems is represented by multi-device applications, where the user can interact with the system through different platforms. However, providing end-users with real capabilities to author user interfaces is still a problematic issue, which is beyond the ability of most end-users today. In this paper, we present an approach intended to enable users to modify Web interfaces easily, considering implicit user intents inferred from example interface modifications carried out by the user. We discuss the design issues involved in the implementation of such an intelligent approach, also reporting on some experimental results obtained from a user test.The work reported in this paper ha been supported by the European Training Network ADVISES, project EU HPRN-CT-2002-00288, and by the Spanish Ministry of Science and Technology (MCyT), projects TIN2005-06885 and TSI2005-08225-C07-0

However, there is an ongoing shift to end-user-centred technology, and even users with poor or no skill in Web-based languages may feel the need to customize Web applications according to their preferences. Although Web authoring environments have an increasing number of features, the challenge of providing end-users with the ability to easily customize entire Web applications still remains unsolved. In this paper, we propose an intelligent approach to customizing Web-based applications. Customizations rules are automatically inferred by the system from changes that users supply as examples. They remain as long-term knowledge that can be applied to support future interactions, thus minimizing the amount of authoring that end-users need to do for this purpose. In order to better understand the implications of the user's modifications, they are analysed using the logical descriptions of the corresponding Web pages.The work reported in this paper is supported by the European Training Network ADVISES (Analysis Design and Validation of Interactive Safety-critical and Error-tolerant Systems), funded through the European Commission.

They pay poor attention to users who have no programming abilities but need to customize software applications. At some point, such needs force end-users to act as designers in various aspects of software authoring and development. Every day, more new computing-related professionals attempt to create and modify existing applications in order to customize web-based artifacts that will help them carry out their daily tasks. In general they are domain experts rather than skilled software designers, and new authoring mechanisms are needed in order that they can accomplish their tasks properly. The work we present is an effort to supply end-users with easy mechanisms for authoring web-based applications. To complement this effort, we present a user study showing that it is possible to carry out a trade-off between expressiveness and ease of use in order to provide end-users with authoring facilities.The work reported in this paper is being partially supported by the Spanish Ministry of Science and Technology (MCyT), projects TIN2005-06885 and TSI2005-08225-C07-06
