Usefulness of an Internet-based thematic learning network: comparison of effectiveness with traditional teaching.

2006

UniNet is an Internet-based thematic network for a virtual community of users (VCU). It supports one multidisciplinary community of doctoral students, who receive most of the courses on the network. The evident advantages of distance learning by Internet, in terms of costs, comfort, etc., require a previous evaluation of the system, focusing on the learning outcomes of the student. The aim was to evaluate the real learning of the students of doctorate courses, by comparing the effectiveness of distance learning in UniNet with traditional classroom-based teaching. Five doctorate courses were taught simultaneously to two independent groups of students in two ways: one, through the UniNet Netw…

Real-time detection of twitter social events from the user's perspective

2015

Over the last 40 years, automatic solutions to analyze text documents collection have been one of the most attractive challenges in the field of information retrieval. More recently, the focus has moved towards dynamic, distributed environments, where documents are continuously created by the users of a virtual community, i.e., the social network. In the case of Twitter, such documents, called tweets, are usually related to events which involve many people in different parts of the world. In this work we present a system for real-time Twitter data analysis which allows to follow a generic event from the user's point of view. The topic detection algorithm we propose is an improved version of…

A Simulation Framework for Evaluating Distributed Reputation Management Systems

2016

In distributed environments, where interactions involve unknown entities, intelligent techniques for estimating agents’ reputation are required. Reputation Management Systems (RMSs) aim to detect malicious behaviors that may affect the integrity of the virtual community. However, these systems are highly dependent of the application domain they address; hence the evaluation of different RMSs in terms of correctness and resistance to security attacks is frequently a tricky task. In this work we present a simulation framework to support researchers in the assessment of a RMS. The simulator is organized in two logic layers where network nodes are mapped to system processes that implement the i…

The influence of belonging to virtual brand communities on consumers' affective commitment, satisfaction and word‐of‐mouth advertising

2011

PurposeThis paper aims to explore some of the effects of belonging to a virtual brand community on consumer behaviour. It also proposes the concept of belonging as a three‐dimensional construct.Design/methodology/approachThe paper proposes that belonging to a virtual community has positive effects on consumer satisfaction, affective commitment and word‐of‐mouth behaviour. After validation of the measurement scales the hypotheses are contrasted through modelling.FindingsThe data show that belonging to a virtual community may enhance consumer satisfaction, affective commitment and word‐of‐mouth advertising towards the brand around which the community is developed. In addition, the paper intro…

A Participant Experience Method for Illustrating Individuals’ Experiences in the Course of an Evolving Virtual Learning Community

2003

Early definitions of virtual learning communities often abstracted participants from their offline environments. However, often students’ virtual and physical environments are not essentially separated. Likewise, scholars should become more sensitive to and aware of their research principles and practices guiding studies in virtual settings and especially, in the intersections of on- and offline contexts. The participant experience method discussed in this paper, grants access also to the events outside the virtual learning context connecting various social settings and simultaneous events. However, the use of participant experience methods requires critical reflection during its various ph…

The Quality of Service Issue in Virtual Environments

2011

Networked virtual environments (NVEs) have become a major trend in distributed computing, mainly due to the enormous popularity of multi-player online games in the entertainment industry. Nowadays, NVE systems are considered as the supporting technology for many networked and virtual organizations (NVO) (Singhal & Zyda, 1999), especially to those classified within the field of computer supported cooperative work (CSCW), where networked computer can be seen as a standard to provide the technological means to support the team design (Ott & Nastansky, 1997). These highly interactive systems simulate a virtual world where multiple users share the same scenario. The system renders the im…
