We live in a rapidly changing digital world marked by technological advances, and fraught with online information constantly growing thanks to the Internet revolution and the online social applications in particular. Formal learning acquired in traditional ...

This paper discusses the 3A recommender system that targets CSCL (computer-supported collaborative learning) and CSCW (computer-supported collaborative work) environments. The proposed system models user interactions in a heterogeneous graph. Then, it appl ...

In this paper, we propose a personalized and contextual ranking algorithm implemented on top of the 3A interaction model. The latter is a generic model intended for designing and describing social and collaborative learning platforms integrating Actors, As ...

Despite the extreme diversity of Web applications, one can find similarities among them. This paper proposes an answer to the question of knowing whether it is possible to conceptually represent different Web applications in a common manner such that they ...

The STELLAR European network of Excellence (NoE) (http://www.stellarnet.eu) represents the effort of leading European institutions and projects in Technology Enhanced Learning (TEL) to unify their diverse and sometimes fragmented community. The Network is ...

Although a plethora of Web 2.0 applications exist today, there is little literature reporting on experiences, concrete recommendations or best practices when developing such applications. The scarcity of such records makes it difficult for developers to de ...

In recent years, the use of chatbots in education has been driven by advances in natural language processing and the increasing availability of digital education platforms. Although the added value of educational chatbots appears promising, researchers hav ...

The e-logbook is a collaborative web-based environment deployed by the Swiss Federal Institute of Technology in Lausanne (EPFL). It consists of an activity-oriented space where a community of educators, teaching assistants and students can form groups, con ...

The recent rise in both popularity and performance of large language models has garnered considerable interest regarding their applicability to education. Technologies like ChatGPT, which can engage in human-like dialog, have already disrupted educational ...

This paper discusses the potential role of social software in supporting teamwork and collaborative project management in higher education. Based on the fact that social software has been widely spread among young students nowadays, using it for collaborat ...

The recent rise in the performance and availability of large language models (LLMs) has fueled the adoption of generative artificial intelligence (AI) to support software engineering. Technologies such as Copilot and ChatGPT have become ubiquitous in softw ...

This paper presents a federated search and social recommen- dation widget. It describes the widget’s interface and the un- derlying social recommendation engine. A preliminary eval- uation of the widget’s usability and usefulness involving 15 subjects is a ...

After years of quest by the computer-supported collaborative work community for true user satisfaction, social software and communities of practice turn out to be the enabling frameworks for natural and effective collaborative learning and knowledge manage ...

This paper reports on the successful use of Graasp, a social media platform, by university students for their collaborative work. Graasp features a number of innovations, such as administrator-free creation of collaborative spaces, context-aware recommenda ...

This paper discusses the adoption of bottom-up social software tools in formal learning environments. This is believed to enhance the learning experience of today’s young generation characterized by being technology savvy and keen on social networking. As ...

Driven by the rising popularity of chatbots such as ChatGPT, there is a budding line of research proposing guidelines for chatbot design, both in general and specifically for digital education. Nevertheless, few researchers have focused on providing concep ...

Benefiting from the advent of social software, information sharing becomes pervasive. Personalized rating systems have emerged to evaluate the quality of user-generated content in open environment and provide recommendation based on users’ past experience. ...

This paper presents the findings of a study on the acceptability in higher education of a Web 2.0 collaborative application, namely eLogbook. The latter offers several features for sustaining collaboration and supporting personal and group learning. It was ...

In the framework of the European Integrated Project PALETTE, the École Polytechnique Fédérale de Lausanne (EPFL) is developing the eLogbook Web 2.0 social software. The purpose of eLogbook is to support tacit and explicit knowledge management in communitie ...
