In recent years, Twitter has become increasingly popular both as a social networking service (where users express their opinions) and as a tool for information retrieval. Many events that are commented, debated or argued online, however, are dynamic and unpredictable in nature, resulting in the need to derive the corresponding dynamic computational methodologies to track and to extract such changing topics, events and relevant content in a timely and unattended manner. In this paper, we propose ...

The widespread of data science programming languages and libraries have raised new interest in teaching computational science coding in ways that leverage the capabilities of both single-computer and cluster-based computation infrastructures. Some of the programming patterns and idioms are converging, yet there are specialized uses and cases that require learners to switch from one to another. In this paper, we report on the experience in action research with more than ten cohorts of mixed backg...

Abstract In the last few years, information and communication technologies (ICTs) and social media have become increasingly relevant to politicians and political parties alike, often used to issue statements or campaigning, among others. At the same time, many citizens have become more involved in politics, partly due to the highly interactive and social environments that the social networking services (SNS) provide. Political events flow through these networks, influencing their users; such eve...

The social media debate preceding the 2016 Brexit referendum represents a yet another instance of the growing role of social networking sites, also known as social media, in steering the dynamics of the socio-political process nowadays. Considering the scale of the phenomenon as well as the variety of concerns it raises vis-a-vis transparency, equality, representation, and legitimacy of the political process, it is imperative to query the mechanisms behind the relationship that unfolds between s...

Abstract Nowadays there is a huge number of learning resources, covered different digital skills, on the Internet. In the framework of European Erasmus+ project: ‘Digital Skills Accelerator’ we developed dedicated to digital skills set of learning resources. Moreover, the test to analyses the level of user digital skills in form of the Online Self-Assessment Tool was developed as well. However, there is a problem with proper identification of personalized digital skills learning pathway. In the ...

Abstract Persistent Identifier (PID) systems have evolved in the last decade to mitigate the problem of link rot and provide unique and resolvable identifiers for digital objects, becoming a key element in archival services. However, they still depend on centralized services which may either become unavailable or cease to behave or be managed as expected. Decentralized technologies may serve as the infrastructure for the design of a trustless PID system over which other incentive mechanisms may ...
