The present study aims to identify the intellectual structure of computed-supported collaborate learning (CSCL) so as to provide more insights into the research trend, the most influential scholars, categories, and regions. This paper analyzed the articles and conference publications derived from Web of Science (WOS) in the field of CSCL from 2006 to 2016. A total of 792 articles were selected and...
This paper proposed a new kind of online education mode, MOOE (Massive Open Online Experiment). MOOE was produced based on the thoughts of the Internet thinking and the opening-and-sharing resources and was the organic combination of MOOC and experimental teaching. The main contributions were made: (1) Instructed MOOE's concept and characteristics. MOOE build a network laboratory with the advanced...
Trend scouting and roadmapping is no longer the task of a small team of specialists. As participation of the crowd can be fostered by applying Web 2.0 technologies the innovation process has become more collaborative. User generated content together with proper navigation and visualization features enables such a process. In this paper two different but similar types of radars are introduced. The...
The objective of this study is to investigate the influence of the use of distributed interface for video discussions with chat groups in electricity teaching for professional education students. The methodology consisted in the application of pre-test, post-test situations and problem as well as the use of questionnaires and focus group. With the results obtained, it was observed evidences the use...
In technological development in the area of e-democracy in-group equality is taken for granted. However, inequality in online communication is just as common as in other social contexts. To research the effects of starting from the presupposition of inequality we have developed a groupware for discussions. Based on democratic meeting techniques and social media it takes the form of a strategic game...
Nowadays Wikis are considered to be a useful tool for teaching and learning. However, well-known Wiki solutions do not provide sufficient facilities for analyzing and exploring networked collaboration. In this paper we present a method for detecting and visualizing structural patterns of collaboration in Wikis. Furthermore we summarize findings from applying our approach on a smaller and two larger...
Aiming at the issues that customers know less parameters about the product, can not describe their customize product feature reasonably and accurately, research on individual product customization technology based on user and item double Fuzzy Clustering under the Internet. User-Item Matrices was double fuzzy clustered through the similarity about the user and the item, searching the nearest item...
This paper presents an environment for molecular visualization with multi-projection and collaboration capabilities between geographically dispersed research groups. It was drafted a hardware and software architecture whose purpose is to reduce the negative effects of the delay in communication inherent long-distance networks.
Technology Navigator is an online tool, developed by IEEE volunteers, which enables students, faculty and professionals in engineering and the sciences to discover engineering content and events relevant to them, including conferences, publications, standards, and published articles. Tags and related tags, often based on a shared “market language,” are filtered across multiple disciplines and industry...
Wiki is a collaborative tool for designing web communications allowing users to edit, add or revise content through a web browser. Despite of various benefits offered by the wikis use, there is no guarantee of a good structure of its content. This occurs especially by the difficulty to graphically visualize the information architecture. In this paper is proposed a Model-Driven Development (MDD) approach...
We explore an user-oriented system implementation based on usability, inteligibility and efficiency aspects for literally and digitally illiterate and semi-literate users. An initial prototype was implemented using Hypothetical User Design Scenarios and its quality was informally evaluated by a little and valid group of users. Next, additional requisites were defined into a second prototype by using...
Several types of 3D software visualizations have been developed to communicate information about the products of a software project and, sometimes, the development process itself. These visualizations have been limited in the degree of interactivity they enabled (primarily panning and zooming) and in their accessibility (since in most cases they assumed a particular client platform). In this paper...
The digital age has brought about new platforms for collaboration which have provided interesting and effective ways of enabling people to engage in a wide variety of socially-driven activities. One only needs to observe the many free/libre open source software projects on the web, where millions of connected individuals actively participate in the development and deployment of a wide range of software...
Collaboration in temporal and spatially distributed environments has consistently had to deal with the challenge of intense awareness, extensively more than locally concentrated team play. Awareness means being informed, in conjunction with an understanding of activities, states and relationships of each individual within a given group as a whole. In multifarious offices, where social interaction...
Group awareness information is important information for group work. It represents things such as group members' roles and responsibilities, their positions on an issue, their status, and the state of various group processes that group members know about when they work together. The group awareness information presented in this article is designed to capture group member activities and their behaviors...
Web-based digital libraries have sped up the process that scholars use to find new, important research papers. Unfortunately, current digital libraries are limited by their inadequate webpage-based paradigm, and it is easy for even the most experienced scholar to get lost. A paper and its immediate references are shown on a webpage, but it is not obvious where that paper belongs in the larger context...
The Internet usage has been growing significantly over the years. Following this trend, collaborative learning tools such as Wikis are becoming increasingly popular. The rise does not respect any social, age, ethnic barriers or those imposed by physical disabilities, including visual. This work presents possibilities for collaboration and challenges to be overcome by visual impaired people interacting...
Dealing with work groups is a challenge for organizations where projects are the main focus. During their activities if cooperation is not adequately coordinated and well supported it can provoke significant delays on the project or can put the final product quality at risk. The goal of this paper is to describe the risks control module, named Risys, to support the execution of project developed by...
The Web today is as much a social space with a participatory culture spurred by online collaboration technologies, as it is an information source. The possibility that almost anyone can contribute content has made credibility assessment online important and difficult at the same time. Empirical studies claim that online credibility perceptions are based more on heuristics than on systematic processing...
Tagging is one of the most popular services in Web 2.0 and folksonomy is a representation of collaborative tagging. Tag cloud has been the one and only visualization of the folksonomy. The tag cloud, however, provides no information about the relations between tags. In this paper, targeting del.icio.us tag data, we propose a technique, FolksoViz, for automatically deriving semantic relations between...
