Brief description

The most famous Hypermedia environment, the Web has been formed to be an integral part of numerous applications in which a user interacts with a service provider, product sellers, governmental organizations, friends and colleagues. Content and services are available at different sources and places. Hence, Web applications need to combine all available knowledge in order to form personalized, user-friendly, and business-optimal services.

Personalization and adaptation to user, vendor needs, and network or machine requirements is therefore an important topic on current hypermedia environments and beyond. In commercial environments, this is known as “the client is the king”. In learning environments, this is “learner centered education”. Although they are much sought after and considered useful, up until recently, adaptive solutions were not so widely spread. Among the reasons one was that they were mainly stand-alone implementations, aimed at specific systems only. This was a serious problem when systems became obsolete, and the created material was not exportable. For authors, this was difficult because it meant that each time they changed the system, the material had to be created from scratch. The users (buyers or learners) had to put up with and learn about many different environments with different reactions. Adaptive solutions being therefore difficult to author/create, to maintain and to use, no wonder that, although considered desirable, not many were employed.

This workshop’s aim is to merge two recent developments in the domains of adaptive hypermedia (AH) and semantic web (SW):

o        AH is moving towards reusable solutions, starting with interfacing exercises with other AH or non-adaptive systems (academia as well as corporate), in order to alleviate the problems outlined above.

o        SW has been built from the very beginning with the goal of reuse, via standards, tools, technologies, machine-interpretable semantics, etc. Recently, after creating the basis tools, SW is moving towards reasoning and personalization mechanisms, therefore creating the basis of exchanging adaptive solutions.

Our planned outcome is therefore to merge these two streams, extracting elements necessary to interface and exchange partial or complete adaptive solutions, based on the experience of these two communities of research: AH and SW.

The aim of this workshop is to bring together researchers and practitioners in the fields of web engineering, adaptive hypermedia, semantic web technologies, knowledge management, information retrieval, user modeling, and other related disciplines which provide enabling technologies for personalization and adaptation on the World Wide Web.



  • design, methodologies and architectures of adaptable and adaptive Web information systems based on Semantic Web
  • authoring and creation of adaptive hypermedia for the Semantic Web
  • personalized taxonomies or ontologies
  • distributed user modelling and adaptation for the Semantic Web
  • automated Semantic Web techniques for generation and updating of user profiles
  • semantic web techniques for adaptation
  • interfacing and interoperability for authoring of adaptive hypermedia
  • interoperability and interfacing adaptive systems: total or partial (modular)
  • interoperability and interfacing corporate and learning environments: total or partial (modular)
  • exchanging domain models, user models, pedagogical models, commercial models, adaptation strategies on the Semantic Web
  • applying Semantic web solutions in interfacing and interoperability
  • adaptive personalized Semantic Web applications
  • Semantic Web solutions for corporate systems
  • Semantic Web solutions for Learning environments
  • Web Services for adaptive systems in the Semantic Web
  • machine learning techniques for information extraction and integration for the Semantic Web

Type of workshop

The workshop will host full papers (20 min presentation, 10 min Q&A) and short papers (10 min presentation, 5 min Q&A) on interfacing systems, models, elements, adaptation languages from the two communities: AH and SW.  The workshop will end with a panel discussion (1 hours) of invited speakers and presenters, with balanced input from the two communities.

Intended audience

There are no restrictions regarding the background of the participants. Thus, both researchers and practitioners will be welcome.

This workshop is also linked with activities performed within the PROLEARN network of excellence; therefore it is partially aimed at members of this network. The problematic of the proposal is however much more general, therefore the intended audience goes beyond it.

The workshop is aimed at all researchers and practitioners that work with or use adaptive hypermedia systems and are interested in durable, reusable solutions, as well as researchers and practitioners that work with or use semantic web technology, and are interested in adding to it and defining the (elements of) adaptation and personalization. We expect that researchers from AH will be able to design more reusable, less ad-hoc systems, that conform to semantic web methodology. We expect that semantic web researchers will benefit from what has already been studied and tested in AH on adaptivity and personalization, and take that into account when extending existing SW languages, descriptions and standards. We expect that practitioners in the fields will leave with a better understanding of the capability that is to be expected from interfacing adaptive solutions, in academic, as well as corporate environments.

Description of activities planned

As has been the case with all previous workshops, at the end of the workshop, all participants will be asked to fill-in questionnaires about their perception of the workshop. These will be collected, processed and results will be displayed online. The papers, discussion issues, powerpoint presentations of the discussions will also be available online.

All workshop participants will be invited, as is already traditional, to have dinner together, for continuing the discussion in a more informal atmosphere.
