This paper presents an ISIS facilities ontology based on keywords in the ISIS Metadata catalog (ICAT) and OntoMaintainer, a web application to facilitate the collaborative development of ontologies. The ISIS facilities ontology aims to organize and make keywords in the ISIS Metadata Catalogue more explicit which will improve the search and navigation of data by category. The Ontology Maintainer...

Dialog game tools are text chat applications which aim to structure and promote students' collaborative learning by having them select a label and sentence-opener for each message they type to their learning partner. In this experiment, we compared students’ learning from discussions via a dialog game tool to their learning via a standard freechat application. Students discussed topic questions...

In this paper an overview of the areas where the Bee Colony Optimization (BCO) and its variants are applied have been given. Bee System was identified by Sato and Hagiwara in 1997 and the Bee Colony Optimization (BCO) was identified by Lucic and Teodorovic in 2001. BCO has emerged as a specialized class of Swarm Intelligence with bees as agents. It is an emerging field for researchers in the fi...

The performance of a new content-free approach to image retrieval is demonstrated. Accumulated user feedback data that specify which images are (ir)relevant to each other and keywords obtained from a network game are recycled through collaborative filtering techniques to retrieve images without analyzing actual image pixels. Experimental results show the proposed method outperforms a convention...

CollabCAD is an indigenous 3D CAD/CAM software system for collaborative design and development of Industrial Designs for strategic use. This work is for CAM module of the indigenous software, in which the development of post-processor is the task that is accomplished. The CAD model is created in CollabCAD and the required tool path was produced in a generic format known as Cutter Location (CL) ...

We report the results of an empirical analysis of learner discourse wherein we analyze the utility of domain keywords in determining the topics of conversation. The results provide a foundation for agent-based feedback to learners in a collaborative learning environment. We also track user actions on a graphical user interface to determine learners’ progress and the quality of their designs.

Knowledge management initiatives of a multinational corporation in Penang are currently deployed via its enterprise-wide portal and Intranet.

Nowadays Web sites tend to be more and more social: users can upload any kind of information on collaborative platforms and can express their opinions about the content they enjoyed through textual feedbacks or reviews. These platforms allow users to annotate resources they like through freely chosen keywords (called tags). The main advantage of these tools is that they perfectly fit user needs...

This paper gives an overview of current trends in manual indexing on the Web. Along with a general rise of user generated content there are more and more tagging systems that allow users to annotate digital resources with tags (keywords) and share their annotations with other users. Tagging is frequently seen in contrast to traditional knowledge organization systems or as something completely n...
