Speaker: Eran Shir, founder and CEO of Dapper Inc. Title: Practical Semantic Web: Web Plumbing 101 The semantic web is a decade old vision promoted by web visionaries like Sir Tim Berners Li in which the web will become a set of semantically interconnected "databases" for programs to interact with, mash together and in general make sense of it all. As a bottom up technological adoption approach, it has failed miserably, and outside some research labs none of its icon technologies ( e.g. RDF/OWL) have gained much traction. In fact, the web has continued to evolve as a messy technological babel tower. We will advocate a new, top-down approach that transforms the existing web into a semantic web, where every site becomes a semantically aware API, using a combination of structure analysis algorithms and user generated effort. We will showcase the Dapper service that allows the creation of semantic APIs from any site and will present the promise such approach holds for the advancement of fields such as semantic search. We will discuss some of the algorithmic challenges faced with when attempting to transform each and every web site into a nicely behaved programmatic lego block. Eran Shir is the founder and CEO of Dapper Inc., a M.Sc. physics graduate from the Technion and a Ph.D. student at the EE-Systems Dept., Tel-Aviv university under the supervision of Dr. Yuval Shavitt. As part of his academic research work, Eran founded in 2004 the DIMES project ( www.netdimes.org) - an international research effort to map the low level infrastructure of the Internet using distributed agents.
