...Luca Mainetti; Roberto Paiano; Davide Bolchini; Andrea Pandurino Purpose Rich Internet Application (RIA) technologies offer designers the opportunity to experiment with novel interaction grammars, whose implications for conceptual modeling still need to be fully understood. An open problem...

...Edelweis Rohrer; Regina Motz; Alicia Diaz Purpose Web site recommendation systems help to get high quality information. The modelling of recommendation systems involves the combination of many features: metrics of quality, quality criteria, recommendation criteria, user profile, and specific...

...Kerstin Altmanninger; Martina Seidl; Manuel Wimmer Purpose The purpose of this paper is to provide a feature‐based characterization of version control systems (VCSs), providing an overview about the state‐of‐the‐art of versioning systems dedicated to modeling artifacts. Design/methodology...

... the types of approximations allowed. A specifically devised index structure which efficiently supports both semantic and structural approximations, according to the specified user preferences, is proposed. Also, a ranking model to quantify approximations in the results is presented. Findings...

...Sami Habib; Maytham Safar Purpose The purpose of this paper is to propose a four‐level hierarchy model for multimedia documents representation to be used during the dynamic scheduling and altering of multimedia contents. Design/methodology/approach The four‐level hierarchy model (object...

...Sean Wolfgand Matsui Siqueira; Maria Helena Lima Baptista Braz; Rubens Nascimento Melo Purpose This paper seeks to present a modeling approach for e‐learning content, describing how to structure e‐learning content and also represent it in OWL DL. Design/methodology/approach This paper presents...

...Cecilia Challiol; Gustavo Rossi; Silvia Gordillo; Valeria De CristÓfolo In this paper we present a model‐based approach for the development of physical hypermedia applications, i.e. those mobile (Web) applications in which physical and digital objects are related and explored using the hypermedia...
