On the Internet, data are distributed on heterogeneous sources. To integrate them in a uniform view, lots of systems based on the famous mediator/wrapper architecture defined by [14] have been designed [3][12]. The data model now admitted for representing data is semi-structured data represented by the XML standard format. Thus now, as well in industry as in research, integration systems using ...

In this paper, we present XPERSim, a 3D simulator built on top of open source components that quickly and easily constructs an accurate and photo-realistic simulation, both visually and dynamically, for robots of arbitrary morphology and of the environment within which it functions. While many existing robot simulators provide a good dynamics simulation, they often lack the high quality visuali...

Web crawlers have been used for nearly a decade as a search engine component to create and update large collections of documents. Typically the crawler and the rest of the search engine are not closely integrated. If the purpose of a search engine is to have as large a collection as possible to serve the general Web community, a close integration may not be necessary. However, if the search eng...

Content integration of web data sources is becoming increasingly important for the formation of the next generation information systems. A common performance bottleneck faced by all proposed solutions is the network overhead incurred when contacting the integrated e-sites. With this paper we contribute ongoing work on D.I.C.E. and Co.In.S.; a domain-independent Content Integration System and it...

The integration of distinct reasoning styles such as the ones exploited by description logics and rule-based systems is still an open challenge because of the differences among them. Such integration may be achieved by following two complementary approaches: loose integration vs. tight integration. Loosely integrated hybrid systems couple existing tools, so they have to handle mutual interactio...

Web Services technology is becoming the de-facto standard for integration of legacy applications within an organisation and for cross organisation enterprise application integration. Much work has gone into specifying Web Services functionality using workflow like techniques and production of software to enact such descriptions. However, most of this software relies on one central server to ena...

Web Services technology is becoming the de-facto standard for integration of legacy applications within an organisation and for cross organisation enterprise application integration (B2BEAI). Much work has gone into specifying Web Services functionality using workflow like techniques (BPEL4WS, WSCI, WSFL, XLANG) and production of software to enact such descriptions. However, most of this softwa...

This paper discusses approaches for system integration in the context of eLearning applications, Learning Management Systems, and Campus Management Systems. Three current projects (elecTUM, CampusSource Engine Integration Platform, and e-Framework) are discussed. Finally a Service Oriented Architecture (SOA) for these integration tasks and an abstraction layer of Campus Management Systems is ou...

In this paper, we describe the design, implementation, and performance characteristics of a complete, industrial-strength XQuery engine, the BEA streaming XQuery processor. The engine was designed to provide very high performance for message processing applications, i.e., for transforming XML data streams, and it is a central component of the 8.1 release of BEA’s WebLogic Integration (WLI) prod...
