The RE-UWA approach to recover user centered conceptual models from Web applications

AbstractThe World Wide Web has become a common platform for interactive software development. Most web applications feature custom user interfaces used by millions of people every day. Information architecture addresses the structural design of information to build quality web applications with improved usability of content, navigation, and findability. One of the most frequently utilized information architecture methods is card sorting—an affordable, user-centered approach for eliciting and evaluating categories and navigable items. Card sorting facilitates decision-making during the development process based on users’ mental models of a given application domain. However, although the qualitative analysis of card sorts has become common practice in information architecture, the quantitative analysis of card sorting is less widely applied. The reason for this gap is that quantitative analysis often requires the use of customized techniques to extract meaningful information for decision-making. To facilitate this process and support the structuring of information, we propose a methodology for the quantitative analysis of card-sorting results in this paper. The suggested approach can be systematically applied to provide clues and support for decisions. These might significantly impact the design and, thus, the final quality of the web application. Therefore, the approach includes proper goodness values that enable comparisons among the results of the methods and techniques used and ensure the suitability of the analyses performed. Two publicly available datasets were used to demonstrate the key issues related to the interpretation of card sorting results and the overall suitability and validity of the proposed methodology.

This chapter presents an extension to Web application conceptual models toward Semantic Web. Conceptual models and model-driven methodologies are widely applied to the development of Web applications because of the advantages they grant in terms of productivity and quality of the outcome. Although some of these approaches are meant to address Semantic Web applications too, they do not fully exploit the whole potential deriving from interaction with ontological data sources and from semantic annotations. The authors claim that Semantic Web applications represent an emerging category of software artifacts, with peculiar characteristics and software structures, and hence need some specific methods and primitives for achieving good design results. In particular the contribution presented in this chapter is an extension of the WebML modeling framework that fulfils most of the design requirements emerging in the new area of Semantic Web. The authors generalize the development process to cover Semantic Web needs and devise a set of new primitives for ontology importing and querying. The chapter also presents a comparison of the proposed approach with the most relevant existing proposals and positioned with respect to the background and adopted technologies.

User Centered

Web technology and internet networks have made web applications the main tool in daily activities. But developing applications with limited time often leads to neglecting the role of the user, which causes a lack of attention to aspects of usability, which results in the failure of the application to meet the needs and desires of the user. In this study we developed an application for submitting credit number determination proposals for engineering functional positions by combining Incremental Prototyping and User Centered Design methods. The results show that the application can meet the usability aspects so that it is easily understood and used in submitting and evaluating proposed credit numbers.Teknologi web dan jaringan internet telah menjadikan aplikasi web sebagai piranti utama dalam kegiatan sehari-hari. Namun pengembangan aplikasi dengan keterbatasan waktu seringkali mengabaikan peran pengguna, yang menyebabkan kurangnya perhatian pada aspek usabilitas sehingga berdampak pada kegagalan aplikasi memenuhi kebutuhan dan keinginan pengguna. Dalam penelitian ini dilakukan pengembangan aplikasi pengajuan usulan penetapan angka kredit (DUPAK) untuk jabatan fungsional perekayasa dengan menggabungkan metode Incremental Prototyping dan User Centered Design. Aplikasi yang dikembangkan terbukti dapat memenuhi aspek usabilitas sehingga dapat mudah dipahami dan digunakan dalam pengajuan dan penilaian usulan angka kredit.
