Semantic Web unleashes your data! The Semantic Web will transform the use of Web data Physicians are acutely aware that each human being is unique. Different sets of genes, medical histories, and environments mean that certain individuals will respond better than others to any given drug. To realize personalized medicine, a physician must consider a patient's lifestyle, living and working environments, medical history, and much more. These patient details must be combined with external information from journal articles, chemical compounds, laboratory results, or standard medical procedures. The challenge, then, is to combine a bewildering array of data sets. The intelligent integration of such diverse data across different domains and sources is daunting. That is the goal of the Semantic Web: let computers do more useful work via the integration of diverse set of data Semantic Web – extends the principles of the Web from documents to data Semantic Web – provides a common framework to share data, enabling a more effective discovery, automation, integration, and re-use across various applications Semantic Web – enables computers and people to work in cooperation Semantic Web – gives information well-defined meaning Semantic Web – allows reasoning over the data and offering different views over the data The Semantic Web is a collaborative effort To learn more, please visit: http://www.w3.org/2001/sw/ Semantic Web – Application areas Businesses, governments, and customers experience an exciting range of possibilities using Semantic Web technologies and applications. Business to Business Semantic Web applications enable flexible and easy data exchange and integration from various sources. Application areas can be: • sharing of project data in R&D, engineering, … • shared human resources • knoweledge engineering Business to Customer Semantic Web helps to build richer services that integrate various information sources, provide better dedicated search and know user preferences. Applications areas can be: • personalised services • specialized information portals Customer to Customer Semantic Web helps to improve communication workflows, social interactions, and exchange of ideas. E-Government Semantic Web helps to integrate various information sources from governmental bodies enabling a seamless interaction between citizens and officials. Applications areas can be: • Semantic Desktop • Personal information management Applications areas can be: • transborder data flow within the nations and continents • improved quality in citizen participation and services. Testimonials on the use of Semantic Web • • • We have a better innovation management leading to faster time-to-market. (by Bankinter) We enhanced search and navigation of a complex corporate Web site. (by Siderean Software & Oracle Corporation) We enabled search of web sites based (also) on their reliability. (by Segala) Other Semantic Web application fields: aerospace, automobile, finance, oil & gas, personal management, pharmacy. Semantic Web – A Web of Data A Web of connected data It contextualizes the use of data through special vocabularies Existing data sources, Web content, or databases can be integrated using Semantic Web technologies Retrieval of information through a unified query interface, regardless how and where data is stored. Semantic Web Structure Rule: RIF - interchange of rules RDFS, OWL - characterization of concepts, terms, and relationships Query: SPARQL - query language and protocol for RDF Data interchange: RDF - resources and their properties Semantic Web applications are not required to use all these technologies: they can choose what they really need
