Aiming at deficiencies of existing knowledge resources management systems, we designed a new collaborative knowledge construction system for massive knowledge resources. By collaborative knowledge building in the following three phases: acquisition of knowledge factors, generation of the local extended topic maps and integration of global extended topic map, we realized a conjunction of concept level...
Mobile cooperative systems can facilitate cooperation by improving the flexibility of usage. However, mobile devices present some constraints that become the design and implementation of groupware systems harder. Additionally, there is a lack of general interface requirements definition and verification techniques for supporting the development of effective mobile groupware systems. This lack makes...
One of the problems affecting fire departments in Latin America is the lack of a strong infrastructure to overcome their communication problems. Because these organizations are mainly volunteer and receive minimal support from government agencies, most existing solutions are not applicable for them. This article presents a low-cost mobile groupware application, which may be used in emergency situations...
By research on topic map standard, the extended topic map (ETM) is proposed as a novel model for organization and management of the massive knowledge resources in e-learning. Based on the model, an extended topic map toolkit is designed and implemented, which allows for operations as exploration, search, consistency check and etc. The ETM toolkit not only provides learners with visual navigation and...
This paper presents an application for collaborative design of mobile prototypes, covering both prototyping and evaluation stages of design. Virtual design workspaces provide designers with the necessary mechanisms to build and test prototypes. Shared versions of these workspaces along with annotation mechanisms offer the ability to not only constitute collaborative design groups, but also perform...
