Profile based multimedia documents adaptation A novel approach for adaptation using an abstract document model

Abstract : The development and innovation in creating new emerging technologies created heterogeneity when accessing the internet nowadays. This heterogeneity induced by both hardware as well as software led multimedia documents to become unstructured and difficult to use. Therefore a growing need for adaptation is raised to adjust existing documents to different states and profiles. This thesis deals with profile based multimedia documents adaptation. This thesis consists of four major parts : the first part outlines a generic survey for recent multimedia document adaptation. The second part, which is our first contribution, is a novel approach where we demonstrate how two parallel versions of a document can help resolve the complex adaptation issue, and how to create a facet for the web in order to allow seamless adaptation and continuous evolution while maintaining adaptability of both existing documents and new documents for emerging technologies. The second contribution of this thesis is the abstract specification of multimedia documents for profile based adaptation, using an abstract document as a substitute for the original one. In the proposed abstract document the processing model helps to achieve the separation between specification and content, while creating two parallel documents. The abstract document model called XMS (XML Multimedia specification) allows to pass only the abstract version of a document to the processing engine and generates the adapted version from the original one using an adapted abstract document. A simple minimal profile is proposed to help make the concept clear. The third major contribution is the spatial specification and manipulation paradigm used in XMS, which is based on a composite spatial relation using a combination of a qualitative distance, a qualitative direction and a qualitative topology in order to specify fairly a two dimensional multimedia document. The paradigm used allows spatial manipulations on the whole spatial specification of a document. The manipulation engine is implemented as a PROLOG based inference system. An abstract minimal web page layout sample is used to exhibit the complex results of spatial manipulation algorithms along with a detailed comparison of XMS for adaptation with other adaptation solutions.
