Mobile collaborative working environment of product design

In response to the arrival of new Web/Internet environments, one of the most attractive challenges in current research is to exploit wireless computing technologies in collaborative product design, and hence to build a ubiquitous mobile information system to enable the collaborative product design within a mobile environment. However, the literature review reveals that although the progress of mobile technologies on wireless networks has largely changed the way people access the Internet; little has been achieved in mobile computing for collaborative product design. The reason is that, due to the distinct features of mobile devices and wireless networks (such as small display screen, limited bandwidth, unreliability of wireless networks, etc.), the methodologies and technologies used in stationary networks are not always applicable to mobile systems. The aim of this research is to establish a Wireless Internet-based Collaborative Working Environment for product design through the combination of multiple technologies, by including: Web services, Parametric Design, the Semantic Web, Agent and Flex Technologies. In order to create, deploy, and manage the distributed resources, Web service is used to implement design resource integration in a platform-independent manner. In addition, Semantic Web Technology is used to create a general knowledge base. This approach includes two components: (1) ontology is used to represent abstract views of product data and (2) added semantic rules are also used to represent relationships among product data. Therefore, an ontology-based description model is thus proposed to facilitate expression and organisation of product information in order to manage and deploy the distributed design resources

Strategic assessment: Using influence diagrams to design distance learning courseware

[[abstract]]Web-based distance learning programs are widely available. A few distance education platform and standards were developed or proposed. The importance of distance learning courseware brought the attention to teachers, administrators, and system developers. Among current software systems, it is hard to realize strategic assessment of student learning performance. Since one of the drawbacks of distance education is the load that an instructor needs to spend in courseware design, as well as to analyze student performance based on course contents and test outcomes, it is worthy to investigate an automatic mechanism to help an instructor to produce effective courseware. Thus, distance learning program can proceed efficiently. In this paper, we develop a mechanism for the construction of course structure based on influence diagram. The mechanism can be implemented as a decision support system for the instructor to analyze the relation among course units and test units. The overall value of a courseware can be systematically analyzed.[[notice]]補正完畢[[journaltype]]國外[[booktype]]紙本[[countrycodes]]DE

CHORUS Deliverable 2.2: Second report - identification of multi-disciplinary key issues for gap analysis toward EU multimedia search engines roadmap

After addressing the state-of-the-art during the first year of Chorus and establishing the existing landscape in multimedia search engines, we have identified and analyzed gaps within European research effort during our second year. In this period we focused on three directions, notably technological issues, user-centred issues and use-cases and socio- economic and legal aspects. These were assessed by two central studies: firstly, a concerted vision of functional breakdown of generic multimedia search engine, and secondly, a representative use-cases descriptions with the related discussion on requirement for technological challenges. Both studies have been carried out in cooperation and consultation with the community at large through EC concertation meetings (multimedia search engines cluster), several meetings with our Think-Tank, presentations in international conferences, and surveys addressed to EU projects coordinators as well as National initiatives coordinators. Based on the obtained feedback we identified two types of gaps, namely core technological gaps that involve research challenges, and “enablers”, which are not necessarily technical research challenges, but have impact on innovation progress. New socio-economic trends are presented as well as emerging legal challenges

Personalised trails and learner profiling in an e-learning environment

This deliverable focuses on personalisation and personalised trails. We begin by introducing and defining the concepts of personalisation and personalised trails. Personalisation requires that a user profile be stored, and so we assess currently available standard profile schemas and discuss the requirements for a profile to support personalised learning. We then review techniques for providing personalisation and some systems that implement these techniques, and discuss some of the issues around evaluating personalisation systems. We look especially at the use of learning and cognitive styles to support personalised learning, and also consider personalisation in the field of mobile learning, which has a slightly different take on the subject, and in commercially available systems, where personalisation support is found to currently be only at quite a low level. We conclude with a summary of the lessons to be learned from our review of personalisation and personalised trails

Feasibility study for developing an event prioritizing system using CMSs

A content management system (CMS) is software that lets users make, modify, publish, and save digital information. These systems provide a piece of software called a plugin, model, or extension that plugs into users' sites and add new functionality or extends existing functionality on the user site. In current events, prioritization is done manually. When changes in event attributes like personnel, logistics, or money happen after the hand-prioritized list of activities is completed, it is not an easy task to reprioritize. By developing an event prioritization plugin, the organizations in need will use it and reduce time and money consumption. This study aims to recognize and evaluate the existing CMSs, their domains, and available plugins. Assess the availability of event prioritization plugins and recommend developing a plugin to help charity organizations to select the best team and resources and conduct the events effectively. The search is done in the area of the developed research questions. Search phrases containing pertinent keywords were used to find primary studies linked to CMSs categorized under journal articles, conference papers, seminars, symposiums, book chapters, and related CMSs websites
