O sublime na propaganda de ódio na Internet - uma análise de discurso

Uma análise comparativa dos métodos de avaliação de sistemas colaborativos fundamentados na engenharia semiótica

Collaborative systems are growing more and more popular. However, evaluating this type of systems is still a difficult task. Many evaluation methods have been proposed to deal with this challenge, but most of them are not yet consolidated. Semiotic Engineering is an explanatory theory about HCI that proposes three different methods that can be applied to evaluate collaborative systems: MIS, MAC...

Uma abordagem para a Busca Contextual de Documentos na Internet

This work presents an approach that constructs automatic tools to help users in searching documents in Internet. Contextual use of the words is analyzed in order to eliminate ambiguities and to discover topics interesting to users. Through successive refinements on searches and with user’s feedback, the set of documents converge to the most relevant ones. The main contribution of this work is t...

Fatores de influência na divisão digital do Brasil: uma análise utilizando Redes Bayesianas

This study aimed to identify factors influencing the digital divide in Brazil. The analysis used data provided by CGI.BR to obtain a different Augmented Naive Bayes network model for each of four variables representing technology adoption: internet use, cell phone use, e-commerce adoption and internet banking adoption. Gender, age, education level, employment status, race, social class, rural /...

Processo de seleção de sistemas integrados: possibilidades de modelagem com base na análise de decisões

Uma análise comparativa dos modelos de sistemas colaborativos fundamentados na engenharia semiótica

There are two models based on Semiotic Engineering aimed to assist designers in modeling the interface: Manas and MoLIC. This work shows the result of the application of these models in two collaborative systems and contrasts the results between models and within each model, assessing which aspects were represented by each model and in what level of abstraction, as well as the possibility of a ...
