    "Yahoo hat angekündigt einige der wesentlichen Standards des semantischen Webs in seine Suchmaschine zu integrieren. Das Unternehmen will einige semantische Web-Indexate in seine Suchtechnik einbauen. Anstatt eine lange Liste von Links auszuspucken, könnte eine semantische Suchmaschine verstehen, welche Art von Objekt oder Person gesucht wird und zusätzliche Information anbieten. Die neue Technologie könnte etablierte Angebote unter Druck setzen, erwarten Experten. Google setzt nach wie vor auf konventionelle Technologie. Der Schachzug des Unternehmens könnte der Verbreitung der Technologie erheblichen Auftrieb geben. Trotz des bemerkenswerten Fortschritts des semantischen Webs der vergangenen Jahre habe der durchschnittliche User davon noch nichts bemerkt, meint Amit Kumar, Product Management Director bei Yahoo. Yahoo habe nun gemerkt, dass sich das langsam ändere. Wie in den Anfangstagen des Web würden viele Menschen Daten mit Kennzeichnungen und Indextermen versehen, die semantische Suchmaschinen brauchen, um das Web zu durchsuchen. Yahoo hat erkannt, dass es nun genug Informationen als Grundlage für eine semantische Websuche gibt."

    "Wie kann man semantische Informationen übermitteln? Die Antwort auf diese Frage ist - zur großen Verwunderung Vieler - nicht einfach XML. Die Standardsprache XML (mit ihren verschiedenen Add-Ons wie Xlink, Xpath) wird heutzutage vielfach benutzt, um Informationen zu übermitteln (etwa mittels XML/EDI für B2B-Transaktionen). Obwohl sie dabei bereits eine deutliche Erleichterung verschafft im Vergleich zu früheren ideosynkratischen Mechanismen (z.B. EDIFACT), ist XML per se nur bedingt geeignet, um semantische Zusammenhänge auszudrücken. Die Struktur eines XMLDokuments ist nicht gleichzusetzen mit der Semantik der darin enthaltenen Informationsbestandteile. Die Schemasprachen DTD (Document Type Definition) und XML-Schema sind zu schwach, um alle semantischen Zusammenhänge zu transportieren. Zur Lösung des Problems wurde ein Schichtenmodell konzipiert. Es baut auf den existierenden Standards für XML mit den Namespace-Mechanismen und XMLSchemadefinitionen auf, um Informationen auf syntaktischer Ebene zu transportieren. Allerdings wird die Ausdrucksfähigkeit von XML deutlich erweitert. Der Erweiterung liegt der Standard RDF (Ressource Description Framework) zugrunde. Mit diesem Ansatz können komplexe Aussagen über Tripel modelliert werden. "Alexander glaubt, dass Andreas ein Experte im Clustering ist", wird repräsentiert durch "Alexander glaubt X",X ist eine Aussage", "Das Subjekt von X ist Andreas",das Prädikat von X ist Experteln" und "das Objekt von X ist Clustering". Jede Ressource wird durch ein URI (Uniform Ressource Identifier) repräsentiert, z.B. wäre für Andreas www.aifb.unikarlsruhe.de/WBS/aho eine mögliche URI. Mit RDF Schema können darüber hinaus Gattungshierarchien aufgebaut werden, etwa um auszudrücken: "Andreas ist ein Experte" oder - exakter dargestellt - "Das Ding" hinter www.aifb.unikarlsruhe.de/WBS/aho ist ein Experte". Die darauf folgenden Ebenen des Schichtenmodells befassen sich mit einer zunehmend feineren Darstellung von inhaltlichen Beziehungen. Zum Beispiel umfassen semantische Technologien sogenannte "Ontologien", die für ein Fachgebiet nicht nur Kategorisierungen, sondern auch Regeln beschreiben. Mit ontologischen Regelmechanismen lassen sich auch implizite Verknüpfungen erkennen."
