First site for Semantic Web ! site is automatically generated using Semantic Web Technology. The content of the site is modelled in an ontology (a formal shared representation of a domain), which formally specifies the concepts and relations relevant for this site (an IST R&D project). The content is represented in the Semantic Web language RDF/S, and is thus accesible for any software agent that commits to the ontology and understands RDF. In other words, the agent should be able to process the publically published ontology in RDFS, and the site content (the instances of the ontology) in RDF. We, humans, can of course not read such languages, and need a more intuitive format. For this reason, we also built an ontology of visualization, in which we can define how the concepts and relations should be visualized. We might even decide to not visualize some concepts or relations. The visualization ontology can be browsed in RDFS. The link between the two ontologies is formed by RDQL (RDF query language). Final visualization is performed through XSL stylesheets. This approach enables us to decouple ''what you see'' from ''what you represent'' in a scalable manner, which is currently a problem with many semantic portals. Both ontologies have been build using the Protege2000 editor of SMI/Stanford. Therefore, you can import the ontologies in Protege [download here], or in any RDF-compatible editor and inspect them.

По Semantic Web Greetings, Semedia ( http://semedia.deit.univpm.it ) is pleased to announce the DBin 0.4 "Barbera" release. ( http://www.dbin.org ) DBin is a platform enabling "Semantic Web Communities", that is, communities of people who want to create and share semantically structured knowledge bases about topics of common interest. (e.g. might be "all about a specific research topic", "Italian Opera", "Vegetarian cooking", "Pubs around the WWW2006 site" etc..) The following screendemo (just a few minutes long) shows DBin in action and explains the main concepts: http://www.dbin.org/screendemo/dbintease.html DBin 0.4 "Barbera" release introduces features such as: * Geotagging and Geobrowsing based on our GMaps and GEarth Eclipse Plugins. GEarth is embedded directly in the rich client interface while GEarth is controlled real time (Great with multiple monitors setup) DBin now can be used for plenty of geotagged based use cases ranging from earth quakes studies, disaster management, wildlife tracking, architecture and urbanistic, ecommerce, ufology.. * Semantic Query driven browser component can be used in brainlets for a variety of purposes * P2P: Much improved knowledge exchange algorithms, more stable and up to 5 times faster * Semantics: Increased OWL support in both the editing and the viewing interface * User Interface: New Look! (Modern SWT), Minimizes to tray icon, property view shows property definitions (when available in the ontology) and "zooms" on complex literals, New quick menu buttons to perform specific actions * Information filtering: New filtering policies based on revocations, Digital user identity (private and public keys) can be stored locally and reused in later DBin installations. * Network: Socks 5 Proxy Support, support for intranet based Knowledge exchange servers DBin is an Open Source project and looks forward to development/research and project proposal cooperations. For those attending WWW2006, we''ll be presenting at dev day, semantic web track, so see you there Giovanni Tummarello, on behalf of the DBin development team ... WSRI ... The Web is the largest human information construct in history. The Web is transforming society. In order to... understand what the Web is engineer its future ensure its social benefit ...we need a new interdisciplinary field that we call Web Science. The Web Science Research Initiative brings together academics, scientists, sociologists, entrepreneurs and decision makers from around the world. These people will create the first multidisciplinary research body to examine the World Wide Web and offer the practical solutions needed to help guide its future use and design.
