Abstract
Enterprise Application Integration (EAI) and Business-to-Business integration are very "hot" topics today in the business world as well as in the academic world. Web Services technologies are touted currently as the Silver Bullet solving all integration problems. Looking closer it becomes clear that Web Services are just a replacement technology for current integration software, not a better solution to the integration problem at all. The fundamental problem that integration solutions suffer from is that the semantics of the entities to be integrated are not formally addressed at all. Semantic Web technology combined with Web Service technology, however, has the ability to describe the integration solution semantically and overcome the current lack of semantics in integration software. This tutorial outlines the integration problem, shows the standards in the space and their limitations from a semantics viewpoint and proposes a set of semantic integration concepts as well as a semantic integration architecture that lifts current integration solutions to a new level of functionality.

2. "Human Language Technology for the Semantic Web" | Dr. Hamish Cunningham | slides
The Semantic Web (SW) is adding a machine-tractable layer to the natural language web of HTML. The Grid initiative is constructing infrastructure for distributed collaborative science, or e-science. Web Services are driving the decomposition of monolithic software into flexible component sets that can be reconfigured to keep ahead in rapidly changing markets. The three areas are closely linked: web technology is essential to the Grid; the Semantic Web and the Grid are co-penetrating to form the Semantic Grid; Web Services underpin the next generation of the Grid in the Open Grid Services Architecture; Semantic Web Services (SWSs) allow dynamic construction of applications from component services, and better service description and discovery.
Together these developments represent the next stage of evolution
for the web, distributed computing and collaborative science. Key to
the success of the enterprise is the production and maintenance of
formal data. The SW and SWSs rely on formal semantics in the shape of
ontologies and related instance sets, or knowledge bases. Whereas the
simplicity of HTML and the ubiquity of natural language led to the
organic growth of the hypertext web, semantic data is harder to create
and maintain.
HLT provides the missing link between language and formal data, the
glue to fix web services to their user constituency and enable easier
enterprise integration.
This tutorial will cover the use of HLT for the Semantic Web and Web Services.
3. "An Introduction to Ontologies & the Semantic Web" | Dr. York Sure | slides
The Semantic Web is an extension of the current web in which information is given well-defined meaning, better enabling computers and people to work in cooperation" [T. Berners-Lee et al., 2001]. The key enabler of the Semantic Web is the need of many communities to put machine-understandable data on the Web which can be shared and processed by automated tools as well as by people. Machines should not just be able to display data, but rather be able to use it for automation, integration and reuse across various applications.
In this tutorial we will present the general idea of the Semantic Web and focus on ontologies as the core underlying technology for realizing it. We will present a detailed view on ontologies, show which tools are needed to build and maintain ontologies and illustrate their usage in existing applications.
4. "Knowledge Discovery & the Semantic Web" | Marko Grobelnik
The tutorial on "Knowledge Discovery & the Semantic Web" will focus on topics contributing to automatic and semi-automatic structuring of textual and other kinds of data (images, networks) which could be used to support the ontology generation (ontology learning) process. The methods described will be mainly from the areas of text mining, link analysis, machine learning and data visualization. The subject of Knowledge Discovery will be presented on various levels, from automatic analysis of atomic data units to identification of higher level concepts and structures in the form of ontologies. Prerequisite knowledge for tutorial attendees is a basic understanding of the complexity appearing in the data (e.g. web and document collections). There will be no need to understand the complexities of the presented approaches (although these will be mentioned). The tutorial will show most of the problems and their solutions through online demonstrations, which will not require deep understanding of the underlying mechanisms.

Peter F. Smolle | Peter.Smolle@netdynamics-tech.com
Peter Smolle born 1941, graduated at the Vienna Technical College TGM and studied then computer science at the Technical University of Vienna. He started his work at ABB Mannheim as technical engineer for the design of rolling mills. He then worked for the Austrian Government as supervisor for subsidized development projects.
In 1970 he joined IBM. During 30 years of IBM experience he gained extensive experience in the entire IT spectrum, covering consulting, design, implementation and management of complex IT projects. He started at IBM as systems engineer for application development, then specialized as systems engineer on data base and application system development projects primarily working for the finance and government industry. Based on the experience out of those projects he made significant contribution to IBM's Insurance Application Architecture (IAA) and also to IBM's application development environment project ADE (Repository) when working on assignment at IBM's software development lab in Santa Teresa , California .
The next "milestone" in his career was the design and concept development of mega integration projects at large customers.
Before joining Net Dynamics, Peter Smolle followed a management career in various IBM departments like business development, solution marketing and finally he led the strategic outsourcing in IBM Global Services.
In the year 2000 Peter Smolle joined and was one of the founders of Net Dynamics Internet Technologies in Vienna .
His current position is Director for Marketing, Business Development
and Sales.
Net Dynamics developed a brand new ontology based multi-agent platform,
which hosts and manages intelligent software agents – FRED. This
platform enables companies in almost every industry to delegate tasks
to FRED. In doing so FRED implements a complete new and low cost way
for collaborative process management, knowledge mining and web service
based application integration. End users will be able to benefit from
the Semantic Web by service based FRED capabilities.
Peter Smolle is also lecturing on different IT related topics at the Donau University of Krems in Austria.
