Chapter
With the experiment that we outline in this paper, we have had the ambition to pave the way for addressing the problem of supporting, enhancing and measuring collective AND informal learning, in particular serendipity. We want to support a new type of free navigation on Web resources (Documents, Topics, Events and Agents – human and artificial -) t...
Article
Full-text available
Collective learning has been advocated to be at the source for innovation, particularly as serendipity seems historically to have been the driving force not only behind innovation, but also behind scientific discovery and artistic creation. Informal learning is well known to represent the most significant learning effects in humans, far better than...
Chapter
Understanding and forecasting brain functions is the major challenge of our times. The focus of this endeavor is understanding and forecasting learning events, such as the dynamic adaptation of beams connecting neuronal cards in Edelman’s Theory of Neuronal Group Selection (TNGS). We have conceived, designed and evaluated a new paradigm for constru...
Chapter
Serendipitous discovery, invention or artistic creation are among the most exciting and utmost relevant phenomena strongly related to human learning. At the moment, there are very few measurable criteria helping to understand and foster serendipity. In other papers [1–3] we have presented, discussed and exemplified a new paradigm/model/method/syste...
Chapter
Collective intelligence is one major outcome of the digital revolution, but this outcome is hardly evaluated. By implementing a topological knowledge graph (KG) in the metaphor of a brain, the ViewpointS approach attempts to trace and assess the dynamics of collaborative knowledge building. Our approach relies on a bipartite graph of resources (age...
Chapter
Tracing knowledge acquisition and linking learning events to interaction between peers is a major challenge of our times. We have conceived, designed and evaluated a new paradigm for constructing and using collective knowledge by Web interactions that we called ViewpointS. By exploiting the similarity with Edelman's Theory of Neuronal Group Selecti...
Article
Formal data is supported by means of specific languages from which the syntax and semantics have to be mastered, which represents an obstacle for collective intelligence. In contrast, informal knowledge relies on weak/ambiguous contributions e.g., I like. Reconciling the two forms of knowledge is a big challenge. We propose a brain-inspired knowled...

This is a position paper describing the author’s views on a potential new research direction for assessing, constructing and exploiting brain-founded models of learning of individual as well as collective humans. The recent approach – called ViewpointS – aiming to unify the Semantic and the Social Web, data mining included, by means of a simple “su...
Conference Paper
The success of online communities depends on different aspects and has been subject of several evaluation works. Most of the existing works in this scope are not generalizable due to their strong dependence to the considered community characteristics. Face to this finding, our aim is to propose a generic approach to evaluate and to improve the succ...
Article
Full-text available
In computer-supported collaborative learning, automatic coding procedure strategies are necessary for teaching because of the large amount of dialogue acts that must be evaluated. In addition, the characterization of a student's social identification for collaborative and learning behaviors might affect a student's learning outcomes in a variety of...
Conference Paper
Full-text available
The Web currently stores two types of content. These contents include linked data from the semantic Web and user contributions from the social Web. Our aim is to represent simplified aspects of these contents within a unified topological model and to harvest the benefits of integrating both content types in order to prompt collective learning and...

Prensky's talk about Digital Natives and Digital Immigrants is often used as a milestone for the field of study addressing this "new generation" of users. However, when talking about Digital Natives the general attitude is to think of them simply as students and not as perspective teachers. This is, in our opinion, a lost opportunity: their way of...

Immanence reflects the principle of emergence of something new from inside a complex system (by opposition to transcendence). For example, immanence occurs when social organization emerges from the internal behaviour of a complex system. In this position paper, we defend the vision that the integration of the Grid and Multi-Agent System (MAS) model...
