Web-based learning environments such as the Go-Lab portal facilitate the structuring and scaffolding of inquiry processes and enable learners to create various types of knowledge artefacts (texts, concept maps, hypotheses). In this context, we have introduced semantic technologies to extract key concepts from heterogeneous learner-generated artefacts. Based on this approach, we propose an algorithm...
In self-managing software teams, developers with complementary skills collaborate with each other to improve productivity and increase innovation. Due to nature of innovation, managers in these teams will acquire only summarized information from developers to avoid micromanagement. They will not plan fine-grained activities but leave responsibility and autonomy to self-managing developers. Developers...
This paper describes the design and development of histoGraph, an interactive tool for explorative visualization and collaborative investigation of historical social networks from multimedia collections. Developed in an interdisciplinary collaboration of computer scientists, historians, HCI researchers and interface designers, the tool aims at supporting historians in the discovery and historical...
The purpose of this paper is to analyze team members' complex scientific research relationships and shape the team's internal complex scientific research networks. The social network analysis method and fuzzy method are used to analyze team members' scientific research relationships on the basis of their cross-citations, collaborations, co-words, bibliographic coupling and co-citations. The team members'...
Serendipity, the process of making fortunate discoveries for which someone was not looking for, plays a critical role in leveraging creativity and innovation. In this paper we propose a framework for facilitating serendipity in web information systems. We focus on three main technological areas which use the World Wide Web as a space for information seeking and knowledge creation: search, browse (navigation)...
This demo introduces V:Issue:lizer, a tool for exploring online communication and analyzing clarification of requirements over time. V:Issue:lizer supports managers and developers to identify requirements with insufficient shared understanding, to analyze communication problems, and to identify developers that are knowledgeable about domain or project related issues through visualizations. Our preliminary...
This paper discussed the Single Deck Bus design development process through an integrated industrial design approach for commercial production. Bus and coach building is a growing industry where the development process frequently ignored to satisfy customer demands and dateline resulted with almost similar facade and lack of design quality. The research applies visual inconsistencies analysis to identify...
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...
The paper describes the design and implementation of a set of visual modeling editors. They aim to provide users with easy to use and customizable but yet semantically powerful tools for collaborative modeling in diverse domains of interest. The tools allow the creation, use and evolution of visual models and their underlying languages. The design, software architecture, technical implementation and...
A novel approach for enabling distributed design of heterogeneous systems and components is introduced in the paper. It integrates concepts of visual knowledge modeling, engineering workflows, collaborative workspaces, design task patterns, and remote tool invocation. These concepts are supported by a collaboration platform a result of the EU FP6 project MAPPER. The design approach and the supporting...
Sources of alternative, clean and smart energies are a demand on our modern world. And as a design project, collaboration and knowledge management are elements that improve the work on multidisciplinary teams. This work describes a collaborative project to construct a Brazilian solid oxide fuel cell, its problems and the solution created to enable a collaborative work on a national context.
