An Application of Multimedia Services on Transportation: The Use of the World Wide Web (WWW)
INTRODUCTION
In recent years, there is an ever-increasing demand and interest in the use of multimedia
technology and applications in industry, government and academia. Multimedia is often
seen by researchers as the next step forward in interfacing science, technology and
community. Yet, the terminology of multimedia bears several meanings. It may refer to
Compact Disc (CD), moving pictures or video-conferencing. The multimedia technology
referred in this paper is the World Wide Web (WWW) hypertext publishing information
system which was developed by and started at the European Laboratory for Particle
Physics (CERN) in Geneva, Switzerland. Since the introduction of WWW, its use has
increased dramatically within a couple of years in a widely diverse community including
government departments, university and research establishments, and commercial
organisations. It has significant influence to our communities and our daily lives. Yet, in
most cases, applications of WWW services are largely restricted to electronic library
referencelcatalogue search facilities, electronic mail systems, electronic conference and
discussion systems, electronic news and publishing agents, and remote access to computing
resources on the Internet.
The primary objective of this paper is to exploit the potential of this multimedia technology
as a simple, easy-to-use and effective means of telematics application in transportation
research. It is hoped that initiatives are highlighted via this study and hence encourage
participations and collaborations from different sectors of industries.
In this paper, a brief history of WWW is given in section (2). An overview of the technical
aspects in providing a WWW service is presented in section (3) in terms of computer
hardware requirements, software installation, network connections, application
maintenance and administration, and system security. Compared to most commercially
available multimedia software in the market, WWW services are cheap to run, userfriendly
and readily available to the public on the Internet. In order to exploit the potential
of WWW on transportation research, a study was carried out and results of the findings are
reported in section (4). To further substantiate the level of usefulness, two particular
WWW applications were chosen amongst other web services and they are reported in
section (5) for illustrative purposes. The selected applications are the 'Transportation
Resources on the Internet' developed in mid-1994 in the Institute for Transport Studies
(ITS) at the University of Leeds in England, and the 'Southern California Real-Time
Traffic Report' developed by Maxwell Laboratories, Inc. in collaboration with the
California State Department of Transportation in the US. Finally, a set of issues are raised
in section (6), highlighting the directions of future development of WWW as an easy-touse,
cheap and effective multimedia telematics application on transportation
Linked Data - the story so far
The term âLinked Dataâ refers to a set of best practices for publishing and connecting structured data on the Web. These best practices have been adopted by an increasing number of data providers over the last three years, leading to the creation of a global data space containing billions of assertionsâ the Web of Data. In this article, the authors present the concept and technical principles of Linked Data, and situate these within the broader context of related technological developments. They describe progress to date in publishing Linked Data on the Web, review applications that have been developed to exploit the Web of Data, and map out a research agenda for the Linked Data community as it moves forward
User centred evaluation of an automatically constructed hyper-textbook
As hypertext systems become widely available and their popularity increases, attention has turned to converting existing textual documents into hypertextual form. An important issue in this area is the fully automatic production of hypertext for learning, teaching, training, or self-referencing. Although many studies have addressed the problem of producing hyper-books, either manually or semi-automatically, the actual usability of hyper-books tools is still an area of ongoing research. This article presents an effort to investigate the effectiveness of a hyper-textbook for self-referencing produced in a fully automatic way. The hyper-textbook is produced using the Hyper-TextBook methodology. We developed a taskbased evaluation scheme and performed a comparative usercentred evaluation between a hyper-textbook and a conventional, printed form of the same textbook. The results indicate that the hyper-textbook, in most cases, improves speed, accuracy, and user satisfaction in comparison to the printed form of the textbook
Web Vulnerability Study of Online Pharmacy Sites
Consumers are increasingly using online pharmacies, but these sites may not provide an adequate level of security with the consumersâ personal data. There is a gap in this research addressing the problems of security vulnerabilities in this industry. The objective is to identify the level of web application security vulnerabilities in online pharmacies and the common types of flaws, thus expanding on prior studies. Technical, managerial and legal recommendations on how to mitigate security issues are presented. The proposed four-step method first consists of choosing an online testing tool. The next steps involve choosing a list of 60 online pharmacy sites to test, and then running the software analysis to compile a list of flaws. Finally, an in-depth analysis is performed on the types of web application vulnerabilities. The majority of sites had serious vulnerabilities, with the majority of flaws being cross-site scripting or old versions of software that have not been updated. A method is proposed for the securing of web pharmacy sites, using a multi-phased approach of technical and managerial techniques together with a thorough understanding of national legal requirements for securing systems
Codes and Hypertext: the Intertextuality of International and Comparative Law
The field of information studies reveals gaps in the literature of international and comparative law as part of interdisciplinary and textual studies. To illustrate the kind of theoretical and text-based work that could be done, this essay provides an example of such a study. Religious law texts, civil law codes, treaties and constitutional texts may provide a means to reveal the nature of hypertext as the new format for commentary. Margins used to be used for commentary, and now this can be done with hypertext and links in footnotes. Scholarly communication in general is now intertextual, and texts derive value and meaning from being related to other texts. This paper draws upon examples chosen after observing relationships between text presentation and hypertext as well as detailing similar observations by scholars to date. However, this essay attempts to go beyond a descriptive level to argue that this intertextuality, and the hypertext nature of the web, bring together texts and traditions in a manner conducive to the study of legal systems and their points of convergence
Citation chain aggregation: An interaction model to support citation cycling
This is the postprint version of the conference paper.Citation chaining is a powerful means of exploring the academic literature. Starting from just one or two known relevant items, a
naĂŻve researcher can cycle backwards and forwards through the citation graph to generate a rich overview of key works, authors and journals relating to their topic. Whilst online citation indexes
greatly facilitate this process, the size and complexity of the search space can rapidly escalate. In this paper, we propose a
novel interaction model called citation chain aggregation (CCA). CCA employs a simple three-list view which highlights the
overlaps that occur between the first-generation relations of known relevant items. As more relevant articles are identified, differences in the frequencies of citations made by or to unseen articles provide strong relevance feedback cues. The benefits of this technique are illustrated using a simple case study
Virtual Office Design For The Effectiveness Of Web_based Office Administration Works
Virtual Office is the science of information technology which is a new thing for some people. The word of virtual has a meaning of visible or tangible, it means that in the future an office is intangible because it will be replaced by a system which is specifically designed to replace the role of office by applying web -based computer programming. Nowdays, Offices have been applied are still using a certain place with a wide range of file and requiring a storage cabinet. These issues triggered the researcher tried to design a virtual office with a concept which is able to handle a variety of problems, ranging from archival storage , searching the archives , phone , video conference , sending letters, categorizing archives and saving faculty and staff data. These concepts developed by the researcher offered well organized data that all files or all archives of administrative office tucked neatly away in a database in well organizing so it made easier in searching a spesific archive. The final objective of the research is the improvement of the workersâ performance because it will shorten the time to manage archives or files. Manufacture of incoming mail, outgoing mail, disposition and also numbering letters will be arranged neatly, thus will increase the effectiveness of a worker. (Abstract
