A Reference Architecture for Adaptive Hypermedia Systems
نویسنده
چکیده
• A typical hypermedia system presents the same links on a page to all users. To eliminate navigation problems the system should offer each user (some) personalized links or navigation tools (such as a table of contents or a map). The system should thereby take into account what the user read before, and possibly what the user’s interests are. • Navigation in ways the author did not anticipate also causes comprehension problems for the user: for every page the author makes an assumption about what foreknowledge the user has when accessing that page. However, this is an impossible authoring task because there are more ways to reach a page than any (human) author can foresee. A page is always presented in the same way. This may result in users visiting pages containing redundant information and pages that they cannot fully understand because they lack some expected foreknowledge.

AH 12 years later: a comprehensive survey of adaptive hypermedia methods and techniques
A hypermedia application offers its users much freedom to navigate through a large hyperspace. Adaptive Hypermedia (AH) offers personalized content, presentation and navigation support. Many Adaptive Hypermedia Systems (AHS) are tightly integrated with one specific application and/or use a limited number of techniques and methods. This makes it difficult to capture all of them in one generic mo...
متن کاملGeneric Adaptation Process
Adaptive Hypermedia Systems (AHS) have long been mainly represented by domainor application-specific systems. Few reference models exist and they provide only a brief overview of how to describe and organize the ‘adaptation process’ in a generic way. In this paper we consider the process aspects of AHS from the very first classical ‘user modelling-adaptation’ loop to a generic detailed flowchar...
متن کاملGeneric Adaptation Framework: a Process-Oriented Perspective
Adaptive Hypermedia Systems (AHS) have long been mostly domainor application-specific systems. Existing reference models provide domain-independent high-level descriptions of AHS. They focus on abstract data structures and only briefly describe the adaptation process in a generic way. In this paper we consider the process aspects of AHS from the very first classical user modelling-adaptation lo...
متن کاملTowards a Common Reference Architecture for Open Hypermedia
This paper contributes to an ongoing effort on standardizing open hypermedia system architectures and communication interfaces. Open hypermedia systems share the property of being able to provide non-hypermedia applications with hypermedia structuring and navigation capabilities. This support is currently provided in many different ways. To be able to standardize communication interfaces, it is...

This paper presents KnowledgeTree, an architecture for adaptive eLearning based on distributed re-usable intelligent learning activities. The goal of KnowledgeTree is to bridge the gap between the modern approach to Web-based education based on learning management systems and powerful but underused intelligent tutoring and adaptive hypermedia technologies. This architecture attempts to address ...
متن کاملGeneric Educational Knowledge Representation for Adaptive and Cognitive Systems
The interoperability of educational systems, encouraged by the development of specifications, standards and tools related to the Semantic Web is limited to the exchange of information in domain and student models. High system interoperability requires that a common framework be defined that represents the functional essence of educational systems. To address this need, we developed a generic mo...
