“…In GPM, a context is a set of generic profiles, each of which describe an autonomous aspect that may influence the adaptation, such as the user, the device, and the location. A number of primitives can be used to represent structured contexts, and we have shown that GPM embeds the main formalisms and languages proposed to express context information [9]. As shown in Fig.…”

“…It is based on a novel methodology for context-aware adaptation of Web data delivery, illustrated in a recent paper [8]. AML provides (1) the description of context information by using a conceptual metamodel [9], (2) the analysis of a Web Application in terms of data content, hypertext structure and presentation, and (3) an extendible set of modeling primitives, representing elementary manipulations, to define a workflow of the adaptation process. Such language is implemented in a CASE tool, so-called FAWIS (a short hand for Flexible Adaptation of Web Information Systems), that is an experimental tool supporting the design and the realization of adaptive data delivery applications over the Web.…”

Modern WWW methodologies focus on developing context-aware data delivery applications on the Web, but very few proposals provide a conceptual modeling of their adaptation specifications. In this paper, we present AML-Adaptation Modeling Language-to specify complex Adaptive Web Applications at the conceptual level. AML models the adaptation process by using a special workflow involving modeling primitives that execute elementary manipulations. The adaptation considers different and orthogonal components of the context and operates over the selection of the most suitable contents, the organization of the hypertext structure of the response, and the layout of the final pages. The language and its design process are fully implemented in a CASE tool, called FAWIS. Specifically, FAWIS is able to access a Web data source and automatically filter and adapt information delivery on the basis of the context of the client. The tool is able to manage heterogeneous contexts, is easy extensible to new coordinates of adaptation, and can integrate different adaptation requirements solving possible conflicts between them. It allows the designer to define the response that better satisfies the requirements of adaptation for a context.

“…Considering the most recent context-aware systems [3,5], they extend the personalization mechanism also to other contexts, such as, for example, the devices used to access the application (e.g., mobile devices), thus offering a more generalized mechanism like in the present approach. However, such systems focus on the acquisition of context data, on their update and on their monitoring, and define reactive behaviors that support adaptivity and can be seen as complementary to our approach.…”

Abstract. The aim of the paper is the introduction of a compositional methodology for specifying context-driven hypertexts, that is the possibility to filter the available -usually too rich-knowledge and personalize the hypertext specification according to the notion of context. We use a methodology and a context model, recently proposed in the database literature, to tailor data on the basis of some predefined aspects on the user, the environment, and the possible scenarios, and we adapt them to specify also the hypertext schemata of the target application. The applicability of the work is shown on a running example and the advantages w.r.t. well known approaches for designing Web applications are highlighted.
