TL;DR: The area of investigacao das Humanidades digitais as mentioned in this paper agrega as ciencias sociais e humanas, as cientícias de computacao e as informacao and documentacao.
Abstract: A area de investigacao das Humanidades Digitais agrega as ciencias sociais e humanas, as ciencias de computacao e as ciencias da informacao e documentacao. Apesar de se ter afirmado recentemente, e extremamente dinâmica, com um numero crescente de organizacoes associadas, eventos promovidos e de jornais editados. As Humanidades Digitais exibem simultaneamente, para cada disciplina, reptos proprios e grandes questoes transversais. Em termos gerais, as linhas de investigacao procuram o entendimento e gestao dos ciclos de vida da informacao de interesse historico e social, para reutilizacao como objeto de estudo pelas comunidades academicas e escolares. Os projetos existentes ou anunciados abrangem variadas areas, destacando-se aqui aqueles que tem relacao mais direta com as ciencias da informacao.

TL;DR: The development of a prototype system able to scan multimedia data, specifically TV broadcasts, and to generate alert messages to users about the relevant information to them is presented.
Abstract: The media monitoring activity is undergoing a large expansion as a consequence of the different emerging media sources. This is pushing the development of automatic systems for selective dissemination of multimedia information. In this paper we present the development of a prototype system able to scan multimedia data, specifically TV broadcasts, and to generate alert messages to users about the relevant information to them. The system makes use of advanced processing technologies for content-based indexing of multimedia information. We use large vocabulary speech recognition system, associated with audio segmentation, and automatic topic indexing and segmentation, to generate category information as semantic markup of multimedia data. The system service is based on a web interface design offering new views of these marked documents and providing useful end-user services based on the content multimedia exploitation.

08 Nov 2011TL;DR: A computational model, based on the Emotional Contagion Scale (ECS), that would enrich group dynamics on virtual environments and suggest that players perceived differences in the emotional contagion susceptibility between those characters and considered the model-based agent significantly more enjoyable and friendlier.
Abstract: Emotions play an important role in social interactions and as such, they are critical in creating engaging and believable characters that users can interact with.Although there has been significant research on emotions, from a computational perspective, one area scarcely explored is the process of Emotional Contagion (EC). Emotional Contagion is the process through which a person's emotional state is influenced by other people's emotions. This process is especially important in group situations where the emotional states of individuals influence the behavior of others.Our goal was to develop a computational model, based on the Emotional Contagion Scale (ECS), that would enrich group dynamics on virtual environments. This model supports agents with different susceptibilities to contagion, and also the influence of their extroversion personality trait and interpersonal relationships (intimacy and power difference) on the contagion process. It has been also included the process of emotional mood decay, as observed in humans. With these elements characterizing the agents at an individual level, this model can simulate a wide variety of social phenomena.To evaluate the model, we developed a game prototype where the player (the main character) goes on a journey with two other characters (one with and another without our model).The results suggest that players perceived differences in the emotional contagion susceptibility between those characters and considered the model-based agent significantly more enjoyable and friendlier.

01 Jan 2012TL;DR: An algorithm based on a reduced palette of 12 colors and on a non-uniform segmentation of the HSV color space using fuzzy membership functions is developed, able to identify the same three dominant colors as users in 50% of the cases, while the classic histogram is only able to identifying 43%.
Abstract: In this paper we propose a solution for the identification of the dominant colors in pictures taking into account the way people perceive them. To that end we developed an algorithm based on a reduced palette of 12 colors and on a non-uniform segmentation of the HSV color space using fuzzy membership functions. Experimental results from an evaluation with users, showed that our algorithm based on the fuzzy histogram is able to identify the same three dominant colors as users in 50% of the cases, while the classic histogram is only able to identify 43%.

19 Oct 2004TL;DR: PoliPer is a middleware platform, capable of providing the needed flexibility for application development and runtime adaptability, so that applications can cope with the multiple requirements and usage diversity found in mobile settings.
Abstract: The need for sharing is well known in a large number of distributed applications. These applications are difficult to develop either for fully wired or mobile wireless networks. Such difficulty arises not only because of slow and unreliable connections in such networks but also due to the great diversity of usage scenarios (even for a single application). Currently, programmers are forced to deal with system-level issues such as replication, consistency, security, etc. PoliPer is a middleware platform, capable of providing the needed flexibility for application development and runtime adaptability. This way, applications can cope with the multiple requirements and usage diversity found in mobile settings. PoliPer relies strongly on the following features: i) the extensible capability to support the specification and enforcement of runtime management policies; ii) a plug-able set of basic mechanisms supporting object replication, security, distributed transactions and code relocation; iii) a set of pre-defined policies that control the mechanisms previously mentioned. Previous systems are either less comprehensive (they address fewer - or just one - aspects than PoliPer), or less flexible (they are not adaptive). A preliminary prototype of PoliPer has been implemented and evaluated with encouraging results.
