Electronic government allows a broad range of citizens to access gov-ernamental information and services, as well as to participate in the government decision-making process. On the other hand, it imposes a higher challenge on a web designer to avoid digital exclusion. Before proposing guidelines to design e-gov sites, it is important to have objective(More)
This paper presents HYRIWYG (How You Rate Influences What You Get), a reputation system applicable to Internet Recommendation Systems (RS). The novelty lies in the incentive mechanism that encourages evaluators to volunteer their true opinion. Honesty is encouraged because rewards are indexed by the quality of the RS's suggestions.
Social networks, such as virtual communities, permit connections between citizen and government. Integrating consultative and deliberative environments for popular participation in democratic issues and creating virtual communities for warranting better relationship among members make it possible to model decision-making processes. For this reason, the(More)

These typically support very selective kinds of perspectives, abstractions and articulation compared to the unlimited possibilities provided by natural languages. This paper reports findings from a(More)
Any Web user is a potential knowledge contributor, but it remains a challenge to make them devote their time contributing to some purpose. In order to align individual with social interests, we selected the CAPTCHA Web resource protection application to embed knowledge elicitation within the users' main task of accessing a Web resource. Consequently, unlike(More)
One of the products of engineering, besides constructed artifacts, is design documentation. To understand how design participants use documentation, we interviewed designers and typical documentation users and also took protocols of them both creating and using design documentation. Our protocols were taken from realistic projects of preliminary design for(More)
