Sharing sensitive information across security domains is an important requirement for knowledge intensive collaborative work, but such sharing may impose risks on security and privacy integrity. Research has increasingly recognized the role of trust in minimizing the risk of information sharing across untrusted or unknown entities. To this extent, trust negotiations[1][3][15][20] have emerged a...

computer-supported collaborative learning (cscl) is a new trend in educational sciences. this study investigates how knowledge sharing and transferring can be facilitated by using cscl in a problem-solving setting. intervention of research is education regarding sustainable water resources management (swrm) by computer-supported collaborative learning (cscl). the purpose of this research was to...

In order to solve the problem of matching the demand and service resources in cloud computing environment, the paper puts forward the concept of a collaborative value chain and analyses the collaborative task units and service resource elements. After that, the paper constructs a model of collaborative value chain and describes in detail the process and methods of matching the collaborative val...

Modern software development is highly knowledge intensive; it requires that software developers create and share new knowledge during their daily work. However, current software development environments are “syntantic”, i.e. they do not facilitate understanding the semantics of software artifacts and hence cannot fully support the knowledge-driven activities of developers. In this paper we pres...

A novel ‘play-by-play’ based procedure learning system has been successfully applied to automate Web tasks. In the transition to a non-Web domain, for a system widely used at US military hospitals, we addressed new challenges by enabling the system to learn collaborative tasks and understand unstructured application environment. This paper presents our approach and its promising evaluation resu...

Researchers put enormous amounts of time and effort into collaborative tasks, such as writing up research proposals or papers. Typically, for such tasks, collaborators use an ad hoc combination of different tools, from version control software, latex editors, instant messaging and emails, to keep track of the tasks status. Time is inevitably wasted in pooling together the various resources and ...

We propose an approach for the integration of collaborative observation and localization within a separate multi-robot mission. The proposed approach will allow individual robots within a team to evaluate and choose a task based on the needs of the mission and the needs, capabilities, and task choices of teammates. Tasks will include mission-related tasks as well as task for self-localization, ...
