Item Enterprise web services-enabled translation framework(Springer Nature Switzerland AG, 2011) Serhani, Mohamed Adel; Jaffar, Ahmed; Campbell, Piers; Atif, Y.Managing multilingual documents is a time consuming, error prone and expensive task, particularly when dealing with dynamic documents such as web contents. A broad spectrum of organizations such as corporations, NGO's and Governments are committed to offer such documents in a number of languages where the content is further localized to suit specific cultural settings. In this paper, we propose a business model supported by a web services-enabled framework, which facilitate all aspects related to multilingual web contents management, from negotiating translation-request quotations through production of final localized output as well as its verification, and delivery. This service is based on a collaborative internet-based translation framework, referred to in this paper as Translation Management System (TMS). Our approach uses XLIFF, a Web service standard developed by OASIS, in order to interoperate enterprise translation services and related Web applications. We present and implement a translation business model centered around standardized processes, which we validate through a case study in the context of a Web translation project. We also propose a QoS monitoring model to satisfy the quality-related requirements of a translation job. Finally, we evaluate the usability of our streamlined Web translation services through users' perception in terms of flexibility, ease of use, and quality of translation. The results revealed interesting performance tradeoffs relative to translation workflows and content-translation accuracy as well as flexibility, and diversity of TMS provided services. © 2010 Springer-Verlag.Item A hybrid cooperative service discovery scheme for mobile services in VANET(Institute of Electrical and Electronics Engineers Inc., 2011) Lakas, Abderrahmane; Serhani, Mohamed Adel; Boulmalf, MohammedDiscovering and accessing services while on the road is an important component in the architecture of future vehicular ad hoc networks, and for a successful deployment of services. Several studies have focused on the design and development of new routing and dissemination techniques that allow vehicles to communicate with each other and with road side units. However, detecting and reaching available services in a vehicular network remains problematic due to the amount of wireless traffic generated when service queries or advertisements are flooded across the network. In this paper, we propose a cooperative hybrid service discovery scheme for discovering services provided by mobile vehicles. This scheme is achieved through cooperating vehicles using store-and-forward approach and by sharing collected service information. We also propose to study the performance of the scheme by varying its degree of reactiveness and proactiveness. It is integrated with a caching mechanism which substantially improves the performance of the service discovery in terms of reduction of the traffic generated, and minimization of the response time while increasing the discovery success rate. © 2011 IEEE.
