Web Design Dimensions and Adaptation

2006

Recent developments in the World Wide Web infrastructure enabled the development of highly interactive hypermedia systems for e-commerce, e-government, and mobile commerce. Such applications have much to gain exploring adaptation, through the use of adaptable and adaptive mechanisms to customize services and interfaces.

The influence of adaptation on hypertext structures and navigation

2010

In adaptive hypertexts the user is guided in two ways: through the existence of links and through link annotation or hiding. Link structures have been investigated, starting with Botafogo et al, and the effect of link annotation has been studied, for instance by Brusilovsky et al. This paper studies the combined effect of link structure and annotation/hiding on the navigation patterns of users. It defines empirical hubs and studies their correlation with hubs as defined by Kleinberg without considering adaptation. The data for the analysis have been extracted from the logs of the course "Hypermedia Structures and Systems," an online adaptive course offered at the Eindhoven University of Technology.

Considering additional adaptation concerns in the design of web applications

2006

Abstract. The design of Web applications traditionally relies heavily on the navigation design. The Web as it evolves now brings additional design concerns, such as omni-presence, device-dependence, privacy, accessibility, localization etc. Many of these additional concerns are occurrences of user-or contextdependency, and are typically realized by transformations of the application (design) that embed adaptation in the navigation.

Web Evolution: Method and Materials

2008

The World Wide Web (Web) is a heterogeneous environment that is in constant evolutionary change. This includes technological changes, the management of data structures used to present the Web content, and guidelines. A lag was noticed between the time these standards and recommendations were introduced to when they were adopted by the developers. This causes a disconnection between the actual user experience, and what was expected by the technology stake-holders. In this study, we investigate the relationship that surrounds these issues, especially those involving the Web user interface. A trend was noticed that new standards and recommendations get adopted faster by the top websites than the random websites. The top websites on average get adopted one year faster than the random websites for a major (X)HTML standards, while it will take on average two years for a graphical format to get adopted. A dip in JavaScript usage was noticed for the past year (2007)(2008), although a continuous increase in AJAX usage was observed, and a growth was predicted to continue for CSS. After ten years < 10% of the websites conform to the WCAG. By understanding these evolutionary trends we can inform and predict Web development into the future. chenqa@cs.man.ac.uk J a n 1 9 9 9 J u l 1 9 9 9 J a n 2 0 0 0 J u l 2 0 0 0 J a n 2 0 0 1 J u l 2 0 0 1 J a n 2 0 0 2 J u l 2 0 0 2 J a n 2 0 0 3 J u l 2 0 0 3 J a n 2 0 0 4 J u l 2 0 0 4 J a n 2 0 0 5 J u l 2 0 0 5 J a n 2 0 0 6 J u l 2 0 0 6 J a n 2 0 0 7 J u l 2 0 0 7 J u n 2 0 0 8 20 J a n 1 9 9 9 J u l 1 9 9 9 J a n 2 0 0 0 J u l 2 0 0 0 J a n 2 0 0 1 J u l 2 0 0 1 J a n 2 0 0 2 J u l 2 0 0 2 J a n 2 0 0 3 J u l 2 0 0 3 J a n 2 0 0 4 J u l 2 0 0 4 J a n 2 0 0 5 J u l 2 0 0 5 J a n 2 0 0 6 J u l 2 0 0 6 J a n 2 0 0 7 J u l 2 0 0 7 J u n 2 0 0 8

AHA! Adding adaptive behavior to websites

Chemical Engineering & Technology, 2003

Most websites offer information that is potentially interesting to a wide audience. However, a single presentation may not be suitable for the wide range of people wishing to visit the website. AHA! is a server extension that makes it possible to adapt the content shown on webpages, and the links that appear on these pages, to each individual user. An AHA! application consists of a concept-structure and a set of XHTML pages. The concept-structure (which can be defined using a high-level graphical tool or a low-level editor) consists of concepts, attributes and condition-action rules that determine user model updates and conditions for object inclusion. The XHTML pages use the "object" tag to indicate where conditionally included objects should be placed. The condition-action rules determine which information is included, if any. The rules also determine the "suitability" of pages for a given user. Links to pages are shown in a different way depending on this suitability. Many adaptive systems exist today. They target a specific application area, like on-line textbooks, information kiosks, corporate information systems, etc. AHA! provides a general-purpose adaptive system. Current research and development efforts concentrate on improving the authoring support, e.g. by automatically detecting potential loops in the condition-action rules. In this paper we refer to upcoming version of the system AHA! 3.0.

Towards a user-adapted information environment on the Web

1998

Abstract: Due to the tremendously increasing popularity of the World-Wide Web, hypermedia is going to be the leading online information medium for some years to come and will most likely become the standard gateway for citizens to the “information highway “. Already today, visitors of web sites are generally heterogeneous and have different needs. The aim of the AVANTI project is to cater hypermedia information to these individual needs by adapting the content and the presentation of web pages to each individual user.

Adaptation and reuse in designing web information systems

2004

Abstract The increasing number of requirements for a Web information system asks for an engineered process in designing such a system. In this paper we focus on two of these requirements: presentation adaptation based on user preferences/device capabilities and reusability of the different design artifacts. Hera is a model-based design methodology for Web information systems. Adaptation and reuse can be tackled at different design levels in Hera.

Gal: A generic adaptation language for describing adaptive hypermedia

2009

Abstract. Nowadays, Web applications have become more sophisticated and interactive, and many of them also offer personalization and adaptation as their features. The mechanisms for these features are typically built on top of specific adaptive engine that has its own engine-specific adaptation language that can be very different from other engines. However, our observation leads to the fact that the main objective of these adaptive engines is the same, that is, to create adaptive navigation structure.
