1st International Semantic Web Conference

Tutorial submission is now over

June 9-12th, 2002

Sardinia, Italia

OntoWeb supported in part by the OntoWeb network

in cooperation with the
DARPA Program

Tutorials will occur on Sunday, June 9th. They can last one day or half a day.

T1: Ontologies: Representation, Engineering, Learning and Applications

Presenters: Alexander Maedche, Steffen Staab (FZI and AIFB, Karlsruhe, DE)
Duration: half day
Prerequisite: basic knowledge about AI and information systems.

Ontologies constitute the foundation for very many intelligent systems nowadays. The have gained popularity for very different needs of groups like the World Wide Web community, the database community and the machine learning community. They are applied to applications and infrastructures like the Semantic Web, information extraction, e-Commerce, or E-Learning applications. The goal of this tutorial is to acquaint the reader with the basics of ontologies that are used for appli-cations: 1.How are they represented? 2.How are they engineered? 3.How can they be learned? 4.How can they be applied? It is the objective of this tutorial to communicate to the audience a comprehensive picture in order to understand the role of ontologies in future information systems.

T2: Description Logics for Conceptual Design, Information Access, and Ontology Integration: Research Trends

Presenter: Enrico Franconi , Dept. of Computer Science, Univ. of Manchester, UK
Duration: half day

Description logics (DL) are a very promising research area in knowledge representation (see The main effort of the research in DL is in providing both theories and systems for expressing structured knowledge and for accessing and reasoning with it in a principled way. Recently, basic progress has been made by establishing the theoretical foundations for the effective use of DL in information systems. DL offer promising formalisms for solving several problems concerning Conceptual Data Modelling and Ontology Design, Intelligent Information Access and Query processing, and Information Integration.
In the tutorial I will argue that good conceptual modelling and ontology design is required to support powerful query management and to allow for semantic based information integration. Therefore, the tutorial has been structured into three parts. In the first part an extended ontology language and a methodology for conceptual and ontology design will be introduced; a demo of the conceptual design tool will be given. In the second part the query management problem in the presence of the previously devised conceptual model will be considered: a global framework will be introduced, together with various basic tasks involved in information access. In the last part general issues about ontology integration will be presented.
This tutorial will have a popular style showing research trends, rather than a strictly theoretical one. Its aim is to let the audience understand why DL technologies could be useful to semantic web research and applications, and it will mostly make use of examples. Nonetheless, precise links to the important theoretical results and to the relevant references will be given.

T3: Semantic web services

Presenters: Christoph Bussler, Dieter Fensel, Terry Payne, Katia Sycara
Duration: full day

Web Services is one of the hot areas in web technology supporting the remote invocation of business functionality over the Internet through message exchange. Research activities as well as industrial developments focus on implementing the mechanisms required for remote invocation and automation of Web Services (using standards such as UDDI, WSDL, X-lang, WSFL, e-speak, .NET etc). Concurrently, the idea and vision of the Semantic Web is catching on and researchers as well as companies have started to realize the benefits of this great vision, which includes ontologies that allow machine-supported data interpretation.
While both efforts are very powerful in themselves, their combination, termed Semantic Web enabled Web Services (SWWS) opens tremendous possibilities. Web services will transform the web from a static collection of information into a distributed device of computation. Semantic Web technology makes the World Wide Web machine-interpretable. Semantic Web enabled Web Services, such as the DAML-S effort, will allow the automatic Discovery, selection and execution of inter-organization business logic making areas like dynamic supply chain composition a reality.
This tutorial brings together theories, challenges, issues, languages and tools from the Semantic Web, Web Services and Agent Technology. We will present the current state of the art in Web-Based Services and sort through the increasing array of relevant tools, languages and theories both from academia and industry. The tutorial includes an exploration of the following:

  • Current state of the art in web service research and industrial standards.
  • Vision and implications of the Semantic Web and Web Service symbiosis.
  • Exploration of the current work and approaches to SWWS


  • Introduction to the Semantic Web and Web Services
  • Web Services: The Vision & Truth
  • Web Services Modeling Framework
  • Semantic Web Enabled Web Services: DAML-S
  • Mediation & Matchmakign
  • Advertising Services
  • Service Process Description & Invocation
  • Discussion & Wrap Up

T4: Jena Tutorial

Presenters: Jeremy Carroll, Brian McBride, Andy Seaborne (HP Labs)
Duration: half day
Prerequisites: Java, basic RDF, basic DAML+OIL, a laptop, a Java IDE

Jena is a leading implementation of RDF within Java, and is widely used by semantic web developers. This tutorial is aimed at the researcher who wishes to be able to start using Jena for developing and deploying semantic web prototypes. The tutorial is a hands-on experience with attendees expected to complete a number of simple exercises. The exercises will form about half the content.
Attendees who already know Jena and wish to consider reusing the material to teach others Jena are also welcome.

After the tutorial you will be able to:

  • Read and write RDF/XML and DAML ontologies from within Jena
  • Create and execute RDQL queries
  • Navigate an RDF graph within Jena:
    • as a graph;
    • using RDQL queries;
    • and using a DAML ontology
  • Navigate a DAML Ontology
  • Introduction to RDF as a graph
  • The Core Jena API
  • Query using RDQL
  • DAML+OIL in Jena
