Automatic Runtime Validation and Correction of the Navigational Design of Web Sites

Abstract

Abstract. Essential to an audience driven website design philosophy is the organization of information and functionality according to the requirements of the different audience classes. However, at design time, it is often difficult to correctly assess the different needs and requirements of the different prospective users of a website. This may result in a non-optimal navigation structure, which will decrease the usability of the website. In this paper, we describe how to correct, at run-time and automatically, possible flaws in the design resulting from incomplete requirement assessment, using adaptive behavior. By observing the browsing behavior of the users, the requirements for the different users are validated and the website is adapted according to adaptation specifications made by the designer. These specifications express when and how the website needs to be adapted and are expressed using an Adaptation Specification Language. The work is presented in the context of an audience driven design method but we also elaborate shortly on the applicability of the technique in general.

A Requirement Analysis Approach for Using i* in Web Engineering

“…WebML [5] also proposes the use of use case diagrams combined with activity diagrams and semi-structured textual description. WSDM [3] is an audience driven approach in which they do a classification of the requirements and the audience. These classes are represented with a diagram in which they are related.…”

“…In the last decade, the number and complexity of websites and the amount of information they offer is rapidly growing. In this context, introduction of Web design methods and methodologies [1,2,3,4,5] have provided mechanisms to develop complex Web applications in a systematic way. To better accommodate the individual user, personalization of websites has been also introduced and studied [6,7,8,9].…”

A survey on web modeling approaches for ubiquitous web applications

“…The web Site Design Method (http://wsdm.vub.ac.be/Research/publications.php) (WSDM), later re‐baptized to web Semantics Design Method (De Troyer et al , 2007), has been first proposed in 1998 (De Troyer and Leune, 1998) and thus, is one of the earliest web modeling approaches. Since its introduction, WSDM has continuously evolved and has been extended by additional concepts addressing localization (De Troyer and Casteleyn, 2004), adaptivity (Casteleyn et al , 2005), accessibility (Plessers et al , 2005a), and semantic annotations (Casteleyn et al , 2006). Recently, WSDM is evolving towards the semantic web (Casteleyn et al , 2006), (De Troyer et al , 2007) (G.T).…”

“…In WSDM's history, two independent proposals for dealing with customization modeling have been published. The first one (Casteleyn et al , 2003), (Casteleyn, 2005), (Casteleyn et al , 2005), focuses on modeling adaptive navigation based on rules specified at design time and triggered due to the browsing behavior of users (C.P). The second one (De Troyer and Casteleyn, 2004), basically extends each of WSDM's development phases (except implementation) in order to model localization.…”

Requirements Engineering in the Development Process of Web Systems: A Systematic Literature Review

“…The development process therefore necessitates knowledge and expertise from many different disciplines and requires a team of diverse groups of people with a high degree of expertise in different areas [2], such as developers, designers and so on, thus making this process even more complex and difficult than normal software development. This has led to the appearance of WE methods such as OOH [3], WSDM [4], WebML [5] and UWE [6] which provide different mechanisms that can be used to consider the content, composition, and navigation features of Web systems, including the appropriate steps needed to consider requirements [7].…”
