Methods and techniques of adaptive hypermedia

Adaptive hypermedia is a new direction of research within the area of adaptive and user model-based interfaces. Adaptive hypermedia (AH) systems build a model of the individual user and apply it for adaptation to that user, for example, to adapt the content of a hypermedia page to the user's knowledge and goals, or to suggest the most relevant links to follow. AH systems are used now in several application areas where the hyperspace is reasonably large and where a hypermedia application is expected to be used by individuals with different goals, knowledge and backgrounds. This paper is a review of existing work on adaptive hypermedia. The paper is centered around a set of identified methods and techniques of AH. It introduces several dimensions of classification of AH systems, methods and techniques and describes the most important of them.

Versioning Support in the HyperProp System

This paper discusses version control for hypermedia models with composite nodes that allow distinct representations of the same information segment to be treated as versions. Several problems arise from the possibility of a node being contained in different nested compositions, as well as being presented (edited) with different representations. The paper discusses these issues, relating partial solutions proposed in several hypermedia models and presenting the proposal defined in the Nested Context Model of the HyperProp system.

Hypermedia presentation generation in Hera

Hera is a model-driven methodology for designing Semantic Web Information Systems (SWIS). Based on the principle of separation-of-concerns, Hera defines models to describe the different aspects of an SWIS. These models are represented using RDF, the foundation language of the Semantic Web. Hera is composed of two phases: the data collection phase, which integrates data from different sources, and the presentation generation phase, which builds a hypermedia presentation for the integrated data. The focus of this paper is on the hypermedia presentation generation phase and the associated model specifications. The Hera presentation generation phase has two variants: a static one that computes at once a full Web presentation, and a dynamic one that computes one-page-at-a-time by letting the user influence the next Web page to be presented. The dynamic variant proposes, in addition to the models from the static variant, new models to capture the data resulted from the user's interaction with the system. The implementation is based on a sequence of data transformations applied to the Hera models that eventually produces a hypermedia presentation.     

Bottom-Up Generation of Hypermedia Documents

Creating hypermedia documents for educational or informational purposes is a time and money consuming task. However, automation, especially for maintaining or adapting large hypermedia documents (e.g. a web site), is a must. This paper presents an approach for the bottom-up generation of hypermedia documents. The main idea is to start with a set of mediaobjects (text, images, video, etc.), select the most appropriate ones, sequence them to build a tree-like structure, integrate them into a set of screen pages, and finally convert each screen page into a single HTML file. Maintaining the resulting document is very easy because it only requires extending or modifying the pool of mediaobjects available and regenerating the document.     

Supporting Composition in a Hypermedia Environment

This paper introduces HCOMET, a composition editor developed to facilitate writing in a hypermedia environment. HCOMET provides an environment for on-line capture and manipulation of ‘thoughts and ideas’ in a multi dimensional and multimedia manner. Composition as a mechanism for structuring and organization of information (to supplement the basic node and link model) is considered an important issue in the future generation of hypermedia systems. This paper discusses the basic issues in supporting composition, and describes the design and implementation of HCOMET. The use of HCOMET in application development is also discussed.     

Modeling the dynamic behavior of hypermedia applications

Hypermedia applications can be defined as collections of interactive and multimedia documents that are organized as a hypertext net. The development of hypermedia applications poses specific problems, such as the need for modeling sophisticated navigational structures, interactive behaviors, and harmonic presentations involving the synchronization of contents. Moreover, the increasing popularity of Internet based systems has put stress on the lack of mechanisms to formally specify security policies when designing hypermedia applications. Traditional design models and methodologies are not suitable for hypermedia applications and the up-to-now developed hypermedia oriented models do not cover the whole set of design needs. In this context, we present Labyrinth, a hypermedia oriented model providing formal elements to describe the static structure and dynamic behavior of this kind of nonlinear, multisensory, and interactive applications

A scenario-based object-oriented hypermedia design methodology

This paper defines an object-oriented methodology for developing hypermedia information systems. The methodology consists of six phases: domain analysis; object modeling; view design; navigation design; implementation design; and construction. Users' requirements are analyzed with a responsibility-driven technology using scenarios. Object-oriented views are generated as the result of object modeling, and then used for the subsequent navigation and implementation design. The implementation design phase deals with database schema, page structure and flow, and user interface. This methodology integrates enterprise databases with distributed hypermedia systems via Internet, Intranet, or Electronic Commerce.
