The most widely adopted approaches for evaluation of summary content follow some protocol for comparing a summary with gold-standard human summaries, which are traditionally called model summaries. This evaluation paradigm falls short when human summaries are not available and becomes less accurate when only a single model is available. We propose three novel evaluation techniques. Two of them ...

In the last years, several research endeavors were launched aiming at involving popular social media platforms in electronic participation. These early endeavors seem to present some essential limitations related mainly to scalability and uptake. In order to avoid these limitations, we introduce a twophased approach for supporting participatory decision-making based on the integration and analy...

The implementation of social media in learning, teaching and cooperation is an innovation process which has implications at many levels in networking universities. eLearning developers and educational designers need to be aware of social media related technological prospects to be able to determine how to benefit from new possibilities. They also need to be aware of related pedagogical possibil...

The traditional debate over skepticism has largely presupposed the framework of foundationalism. With the rise of the intemalism/externalism debate in epistemology, however, it is apparent that there are radically different ways to understand foundational justification. In this chapter we begin by examining the traditional epistemic regress argument for foundationalism. Before presenting what I...

People learn social cue-outcome relationships and use this knowledge to guide their behavior, even in the absence of explicit knowledge of social contingencies. The aim of the current study was to investigate variations in implicit social learning abilities between typically developed individuals with low and high number of autistic traits, as assessed by the AQ questionnaire. In the learning p...

It is widely accepted that initial adoption is critical to innovation success. A less recognized argument in the information System (IS) field is that post-adoption use of an innovation is equally important, if not more important than its initial acceptance. Drawing on the popular Unified Theory of Acceptance and Use Technology (UTAUT) model (Venkatesh et al. 2003) while adopting the Integrativ...

Contemporary capitalism is often described as a economical system based on knowledge, whats indicate a shift from material production to more intangible assets related to exchange, control and circulation. It is strictly connected with something what we can define as a 'language (or communicative) turn' in debate on contemporary city, and particularly on public space. Architects and many urban ...

We describe a framework for representing email as well as meeting information as a joint graph. In the graph, documents and meeting descriptions are connected via other nontextual objects representing the underlying structure-rich data. This framework integrates content, social networks and a timeline in a structural graph. Extended similarity metrics for objects embedded in the graph can be de...
