Service-Oriented Architecture is a cornerstone for the realization of the user's needs through the automatic composition of services from service descriptions and user tasks. Yet, automatic service composition processes commonly assume that Linguistic Web Service descriptions and user requests share the same abstraction level, and that services have been pre-designed to integrate. In this paper, we...
Managing hierarchies is an ever-recurring challenge for relational database systems. Through investigations of customer scenarios at SAP we found that today's RDBMSs still leave a lot to be desired in order to meet the requirements of typical applications. Our research puts a new twist on handling hierarchies in SQL-based systems. We present an approach for modeling hierarchical data natively, and...
Source code analyzer is a tool for analyzing source code that aim to improve the quality of programs in software development. This research enhanced the ability of source code analyzer for automatic grading of programming assignments. The automatic grading process runs in three phases: (a) source code analysis by source code analyzer, (b) analytical results unification, and (c) unification results...
The management of temporal data is a crucial issue in many applications. Recently, XML has become the standard for data exchange and representation. Consequently, important efforts have been made on the development of temporal extensions for XML. This paper investigates how to generate or maintain space-efficient time-stamped documents. We formally define a notion of compactness which allows for comparing...
Virtual Reality(VR) and e-Government Technology both are achieved significant development in recent years, which provides possibility to realize anthropomorphic e-Government based on “anywhere” Internet. To reduce the big gap between VR Technology and e-Government application in terms of Technology Architecture and Development Process, in this paper, a design method on VR service Engine is proposed...
We present a system for managing the screen real estate of interactive public displays with declarative XML-based descriptions of virtual screens and a finite state machine. The proposed approach includes an algorithm for transforming the declarative virtual screens into a sequence of steps required for transiting between layout states. The system is utilized in realizing an interaction model for...
As the deployment of wireless sensor networks increase and their application domain widens, the opportunity for effective use of XML filtering and streaming query engines is ever more present. XML filtering engines aim to provide efficient real-time querying of streaming XML encoded data. This paper provides a detailed analysis of several such engines, focusing on the technology involved, their capabilities,...
Multimedia content adaptation is gaining importance because of the growing amount of multimedia content on the one hand and the growing diversity in usage environments on the other hand. Furthermore, to deal with the growing amount of coding formats for multimedia content, format-independent adaptation systems are desired. These systems support the exploitation of scalability to meet the usage environment,...
