Abstract: In recent years the development of ontologies - explicit formal specifications of the terms in the domain and relations among them -has been moving from the realm of Artificial-Intelligence laboratories to the desktops of domain experts. Ontologies have also become common on the World-Wide Web. The ontologies on the Web range from large taxonomies categorizing Web sites (such as on Yahoo!) to categorizations of products for sale and their features (such as on Amazon.com). On the Web and in many large applications ontologies serve a variety of purposes: making the knowledge about a particular domain explicit, sharing and reusing this knowledge, analyzing domain knowledge. A number of languages for defining ontologies on the Web, such as RDF(S) and DAML+OIL, are under development. In this tutorial we will discuss why one would build an ontology and present a methodology for creating ontologies based on declarative knowledge representation systems. We will present ontology examples, discuss common problems and pitfalls in ontology development and approaches to solving the problems. We will also give a brief overview of the current research issues in ontology engineering and compare some Web-based ontology-representation languages.

Abstract: This tutorial will give an introduction to the field of business-to-business (B2B) integration from a technical viewpoint with the focus on semantic integration aspects. The set of B2B integration concepts is introduced as well as their implementation in form of a technical semantic B2B integration architecture. A mix of examples is taken illustrating the problems that need to be solved in semantic B2B integration projects. The tutorial enables the audience to identify semantic B2B integration problems as well as to determine the benefits and deficiencies of various technical integration architecture approaches or B2B integration technologies.

Abstract: E-services are business functions made available via the Internet by service providers, and accessible by clients that could be human users or software applications. The main benefit of the e-services environment is that clients are able to dynamically discover the available e-service that best meets their needs, to examine its properties and capabilities, and to determine if and how to access it. However, in order to deliver e-services to clients, service providers are faced with several challenges. In particular, they need to describe e-services in a way that is accessible and understandable by the clients and to advertise them in web directories, so that they can be discovered by brokers as well as by end -users. In this tutorial we discuss the main requirements for models and languages for service description and discovery, and we present relevant approaches proposed by standardization consortia.
