HaMA

Abstract

Nowadays, multimedia documents are omnipresent at any time from and to any devices. However, mobile devices heterogeneity and the various contexts of the user require their adaptation. In this context, the existing systems transform contents to comply with the target constraints. Nevertheless, the current solutions do not exploit the profile semantic benefits to reason upon the context for assisting the adaptation. Furthermore, there is no work that care of adapting HTML pages containing CSS and changing in time, where time specification is declarative (e.g. by means of timesheets). This paper provides an adaptation approach called “Handicap-based Multimedia Adaptation” (HaMA), in which each context constraint corresponds to handicap types in order to discover adaptation services. Thus, a generic ontology is introduced to reason upon the context and then deduces the corresponding handicap in order to infer the suitable adaptation guideline. Also, we propose a method for selecting appropriate services with respect to quality criteria. To validate HaMA, scenarios were implemented.

On the use of historical data in context-aware multimedia documents adaptation processes

“…No support of the compatibility between the inferred adaptation actions. Saighi et al (2017) [12] Server-side A handicap-based MDA that exploits an ontology to provide context-aware assistance by binding each context constraint to a physical handicap and thus to an adaptation action.…”

“…In fact, from a functional point of view, most MDA processes work very well. However, when it comes to validating a given adaptation approach, the prototypes developed are often based on simulation to collect context elements; mainly for the elements related to connected objects (see for example [11], [12], [20]). Indeed, even if the simulation paradigm is very useful in many situations, the realization of a real prototype remains the most ideal, realistic and viable solution, in particular to deal with technical, and implementation issues.…”

“…Table 5 gives details of a subset of typical adaptation actions. To build these rules, we are inspired by those used in [12], [20].…”

A Multi-Viewpoint Approach For Semantic Multimedia Documents Adaptation

“…In the literature, several multimedia document adaptation approaches are proposed. These approaches take as input profile information and multimedia documents in order to provide adapted documents [7,8,9,10,11]. In what follows, we examine some relevant works in the field.…”
