    Adoubés par Tim Berners Lee lui-même, les wikis sémantiques sont "des wikis dans lesquels on peut ajouter des données, les extraire, les manipuler en utilisant toutes sortes d'outils du web sémantique". Exposés ainsi, on ne voit pas forcément la d...

  • Most of the Web's content today is designed for humans to read, not for computer programs to manipulate meaningfully. Computers can adeptly parse Web pages for layout and routine processing—here a header, there a link to another page—but in general, computers have no reliable way to process the semantics
  • The Semantic Web will bring structure to the meaningful content of Web pages, creating an environment where software agents roaming from page to page can readily carry out sophisticated tasks for users.
  • The Semantic Web is not a separate Web but an extension of the current one
  • ...8 more annotations...
  • To date, the Web has developed most rapidly as a medium of documents for people rather than for data and information that can be processed automatically.
  • For the semantic web to function, computers must have access to structured collections of information and sets of inference rules that they can use to conduct automated reasoning.
  • Semantic Web researchers, in contrast, accept that paradoxes and unanswerable questions are a price that must be paid to achieve versatility.
  • Adding logic to the Web—the means to use rules to make inferences, choose courses of action and answer questions—is the task before the Semantic Web community at the moment.
  • Two important technologies for developing the Semantic Web are already in place: eXtensible Markup Language (XML) and the Resource Description Framework (RDF).
  • Subject and object are each identified by a Universal Resource Identifier (URI), just as used in a link on a Web page.
  • the URIs ensure that concepts are not just words in a document but are tied to a unique definition that everyone can find on the Web
  • The semantic web is not "merely" the tool for conducting individual tasks that we have discussed so far. In addition, if properly designed, the Semantic Web can assist the evolution of human knowledge as a whole.

  • the URIs ensure that concepts are not just words in a document but are tied to a unique definition that everyone can find on the Web.
  • he third basic component of the Semantic Web, collections of information called ontologies.
  • an ontology is a document or file that formally defines the relations among terms. The most typical kind of ontology for the Web has a taxonomy and a set of inference rules.
  • even agents that were not expressly designed to work together can transfer data among themselves when the data come with semantics.
  • your computer asks the service for a proof of its answer
  • Another vital feature will be digital signatures, which are encrypted blocks of data that computers and agents can use to verify that the attached information has been provided by a specific trusted source
  • URIs can point to anything, including physical entities, which means we can use the RDF language to describe devices such as cell phones and TVs.
  • The semantic web is not "merely" the tool for conducting individual tasks that we have discussed so far. In addition, if properly designed, the Semantic Web can assist the evolution of human knowledge as a whole.
