Semantic Web is a concept that enables better machine proccesing of information on the Web, by structuring documents written for the Web in such a way that they become understandable by machines. This can be used for creating more complex applications (intelligent browsers, more advanced Web agents), global databases with the data from the Web, reuse of information, etc.

This tutorial explains all above, using both the basic theory and the appropriate examples. Semantic modeling languages like the Resource Description Framework (RDF) and topic maps employ XML syntax to achieve this objective. New tools exploit cross domain vocabularies to automatically extract and relate the meta information in a new context. Web Ontology languages like DAML+OIL extend RDF with richer modeling primitives and provide a technological basis to enable the Semantic Web. These concepts are explained thru examples and case studies. Finally, the logic languages for Semantic Web are discussed (which build on the top of RDF and ontology languages). They, together with digital signatures, enable a web of trust, which will have levels of trust for its resources and for the rights of access, and will enable generating proofs for the actions and resources on the Web.

This tutorial was the most attended tutorial at several conferences in the recent past!

Prof. Veljko Milutinović

Prof. Milutinovic was responsible for the architecture/design of the world's first 200MHz microprocessor, for US defence agency DARPA, about a decade before Intel (in GaAs technology).

He published about 50 papers in IEEE journals and about 20 books (for major publishers in the USA: Wiley, Prentice-Hall, North- Holland, etc.). For 7 of his edited books, forewords were written by 7 different Nobel Prize winners, and 3 of his original books (himself as a single author) were bestsellers for their publishers in the USA (Wiley, IEEE CS Press, Kluwer).

His Ph.D. is from U. of Belgrade; after that for about a decade he was on the faculty of Purdue University in the USA (one of the top 5 out of about 2000 USA schools in electrical and computer engineering). He returned to Belgrade in 1990 (so as not to miss any of the excitements in that part of the World, during the decade of 90s). There he continued to do consulting and product developments for the cutting edge industry in the USA (he has consulted for Intel, Honeywell, IBM, SUN, and others, and he is credited for some of the advanced features in the recent products of NCR, COMPAQ, Virtual, MainStreetNetworks, and others).

His work is referenced extensively in SCI (over 100 times), plus in numerous conference papers and university textbooks (he is the most referenced author in several well known books of the major USA publishers, by authors from Stanford, Harvard, Boston, MIT, etc).

His current research is in infrastructure (software systems and related hardware accelerators) for e-business on the Internet. He served on the Scientific Advisory Boards of several start-ups in the USA, and is the General Chair of the successfull series of IPSI conferences (

He is a Fellow of the IEEE.
