Most Web applications, besides the increasing support to functionalities and services will continue aiming at showing and delivering multimedia content. This basic feature that stems from the early Web 1.0 applications is currently empowered by the Web 2.0 and follow-on applications. Web 2.0 applications rely strongly on actual users editing, sharing, collaborating, and performing content tasks in real contexts of use. In this tutorial, we first present the particular characteristics of Web applications, particularly, the so-called Web 2.0 ones.

Second, we show how to specify quality requirements for functions, services and content for these applications, employing a minimalist and integrated approach. By reusing and extending the ISO 25010 quality models’ characteristics, we discuss the need of modelling and adding the content characteristic for evaluating the quality of information. Specifically, we argue that the internal and external quality models with the set of eigth characteristics, i.e. functional suitability, operability, reliability, security, performance efficiency, compatibility, transferability, maintainability, and their sub-characteristics respectively, are not sufficient to specify Web applications’ information quality requirements. As a consequence, we propose to include in both models the content characteristic and its sub-characteristics, i.e. content accuracy, content suitability, content accessibility, and content legal compliance.

Third, we give clues how these characteristics and attributes can be measured and evaluated regarding our measurement and evaluation approach and different methods. In order to illustate the main concepts, an example on the content dimension is developed.

Participation in this workshop is free for conference attendees only. Registration required.

Luis Olsina is a Full Professor in the Engineering School at the National University of La Pampa, Argentina, and heads the Software and Web Engineering R&D group (GIDIS_Web). His research interests include Web engineering, particularly, Web quality assurance strategies, quantitative evaluation methods, Web metrics and indicators, organizational memories, and ontologies. He earned a PhD in the area of software engineering and a MSE from National University of La Plata, Argentina.

In the last 14 years, he has published over 80 refereed papers, and participated in numerous regional and international events both as program committee chair and member. Particularly, he co-chaired the Web Engineering Workshop held in USA in the framework of ICSE 2002 (Int’l Conference on Software Engineering); the ICWE 2002 congress (held in Argentina) and ICWE 2003 (held in Spain); in addition to LA-Web 2005 and 2008 editions and the WE track at WWW’06 (held in Edinburgh, UK). He has been an invited speaker at several conferences and professional meetings, and presented tutorials, for instance, at ICWE’05 (Int’l Conference on Web Engineering held in Australia), ICWE’09 (held in Spain), and graduate courses in different countries. Recently, Luis and his colleagues have co-edited the book titled Web Engineering: Modelling and Implementing Web Applications published by Springer, HCIS Series, 2008.
