Olle Olsson, SICS/W3C, SwedenOlle Olsson works at the Swedish InstituteofComputer Science, SICS (http://www.sics.se ), an international research institute within the field of IKT. There he has been active in areas of expert systems, knowledge representation, agent technology, and conceptual modelling. He also holds the responsibility for the Swedish W3C office (http://www.w3c.se), which is part of the global “World Wide Web Consortium", W3C (http://www.w3.org). Among other things, W3C develops open (i.e. non-proprietary) standards for web languages and protocols for the semantic web.

The Semantic WebThe web and web technologies are developing quickly and the services are adopted at high speed. Web 2.0 and Ajax are known terms. The semantic web is regarded as being the next step in the development process and has even started being referred to as “Web 3.0". So, what is the semantic web? And how can we develop our information and our IT platform, to benefit from the advantages of this new web paradigm? The aim of this presentation is to create a concrete picture of the semantic web and its technologies. An important linchpin is the fact that the semantic web is concentrated on tying data together on the web, and representing information in a way which enables us to mechanically obtain interoperability (on information level). A prerequisite for this is that information is marked by meaning units and that various markings, based on compatible conceptual models, can be linked. This is what constitutes the “semantics" - that the marking is based on the importance of the information. There is already a set of technologies for the semantic web, of which the most known are RDF, OWL and SPARQL. These are all included in the tool box of semantic technologies. How are they used? How do they interrelate? And how is this connected to other web technologies, as for instance XML, HTML, and WSDL? We have the basic technologies in place, but already complementary technologies are developed - technologies supporting the use of semantic technologies in specialised contexts.What about practical usage? Who have adopted the semantic technologies, and what are they using them for? Concrete examples of usage give a good insight into where the market usage stands today, what are reasonable approaches and what is going on. Some examples, as inspiration for the mind.And what about products in the field? That is, what type of support does one need and what is available? The current situation is illustrated, as well as the prognosis for the future. There are also some interesting relations between the semantic web and parts of what we can see within the Web 2.0 world.
