What is a Semantic Web Application?

A Semantic Web Application has to meet the following minimal requirements.
  1. First, the information sources used
    • should be geographically distributed,
    • should have diverse ownerships (i.e. there is no control of evolution),
    • should be heterogeneous (syntactically, structurally, and semantically), and
    • should contain real world data, i.e. are more than toy examples.

  2. Second, it is required that all applications assume an open world, i.e. assume that the information is never complete.
  3. Finally, the applications should use some formal description of the meaning of the data.

What are the additional desires?

Besides the minimal criteria,a number of desires are formulated. The more desires are met, the higher an application can score. The desires are:
  • The application uses data sources for other purposes or in another way than originally intended
  • Using the contents of multi-media documents
  • Accessibility in multiple languages
  • Accessibility via devices other than the PC
  • Other applications than pure information retrieval
  • Combination of static and dynamic knowledge (e.g. combination of static ontologies and dynamic work-flows)
  • The results should be as accurate as possible (e.g. use a ranking of results according to validity)
  • The application should be scalable (in terms of the amount of data used and in terms of distributed components working together)

How to participate

Visit http://challenge.semanticweb.org in order to participate and register for the Semantic Web Challenge by submitting the required information as well as a link to the application on the online registration form. The form will be open until June 15, 2005, 12 p.m. CET. The requirements of this entry are:
  1. Abstract: no more than 200 words.
  2. Description: The description will show details of the system including why the system is innovative, which features or functions the system provides, and why it is relevant to the challenge. Examples of its use must be provided and if the application includes the additional desires these should be mentioned. The description should not exceed four pages (LNCS format). Selected descriptions will be published in the conference proceedings.
  3. Accessibility: The application should be accessible via the web. If the application is not publicly accessible, passwords should be provided. We also ask to provide a (short) instruction on how to start and use the application.

Prizes

The prizes for the winners are available as travel support and book vouchers:
  1. Prize: 1.000 travel support plus 250 books
  2. Prize: 500 travel support plus 250 books
  3. Prize: 250 travel support plus 250 books
The winners will also be asked to give a live demonstration of their application at the ISWC 2005 conference.
