Collaborative querying seeks to help users formulate queries by sharing expert knowledge or other users’ search experiences. This paper reports evaluation results for a collaborative querying environment. Our results show that compared with traditional information retrieval environments, collaborative querying can lead to faster information seeking when users perform unspecified tasks.

In the conventional system development life cycle (SDLC), system performance and evaluation phase comes after the implementation phase. The aim of this research is to project system performance estimate at the requirement analysis and design phase itself, much before the implementation phase. This study introduces novel tools for modelling the system, evaluating the performance of the system an...

The paper focuses on the domain of user behaviour evaluation in the collaborative processes performed in a virtual user environment. Proposed historical projection of activities performed in such an environment provides several analytic perspectives materialised in form of different tools, but all of them are based on suitable visualization and extraction techniques. The differences are based o...

With the development of synthetic aperture radar (SAR) technologies in recent years, the huge amount of remote sensing data brings challenges for real-time imaging processing. Therefore, high performance computing (HPC) methods have been presented to accelerate SAR imaging, especially the GPU based methods. In the classical GPU based imaging algorithm, GPU is employed to accelerate image proces...

In high-reliability work settings, most human work is performed by teams of workers who often engage in collaborative information behavior to solve complex problems. In this paper, we examine collaborative information behavior of trauma teams during trauma resuscitation, a team-dependent, fast-paced and information-laden process of evaluating critically injured patients early after injury. We i...

Collaboration in the information seeking and retrieval environment is common, particularly when the search task is complex and exploratory. Multiple factors such as contextual features and task type can affect users’ query behavior. This paper presents a study investigating the effects of collaboration and task types on users’ query behavior. The study involves two conditions: collaborative sea...

e-Learning platforms allow users to collaborate with one other. Moodle, as one of the main e-Learning platforms, provides tools to perform collaborative tasks. With these tasks, students are able to share documents and information. The means provided by Moodle are not enough to perform some collaborative tasks, such as sharing documents in real-time. In this scenario users must be aware of what...

We present the MUSHI (Multi-User Simulation with Handheld Integration) framework, which was designed to support middle and high school students in the acquisition of scientific concepts rooted in complex, multi-scalar phenomena. In designing a learning environment that is conducive to collaborative inquiry learning, we have combined a dynamic simulation with wirelessly-connected handheld device...

This paper characterizes collaborative learning systems and identifies some of the dimensions of collaborative learning research. Overview Collaborative learning deals with instructional methods that seek to promote learning through collaborative efforts among students working on a given learning task. Computer Supported Collaborative learning (CSCL) delivers a collaborative environment that de...
