    Content
    Lizenzfreie Bilder mit einer Suchmaschine aufstöbern Im Internet gibt es fast auf jeder Website Bilder, die Sie im Browser auf Ihrer Festplatte speichern und in anderen Anwendungen weiterverarbeiten können. Entsprechend riesig ist das Gesamtangebot an Fotos, Grafiken und Clipart-Elementen. Allerdings dürfen Sie Grafikelemente, die in eine Website eingebaut sind, nur dann für eigene Zwecke einsetzen, wenn der Urheber das ausdrücklich gestattet. Diese Erlaubnis ist normalerweise mit einem Begriff wie "rechtefrei", "lizenzfrei", "zur freien Nutzung" oder -englischsprachig - "royalty-free" gekennzeichnet. Das Problem: Auf den meisten Websites finden Sie keine Urheberrechtshinweise zu den eingebetteten Bildern. Am einfachsten ist die Suche nach lizenzfreien Web-Bildern mit einer für Grafiken und Fotos optimierten Suchmaschine wie Google (www.google.de), Fotos.de (www. fotos.de) oder Picsearch (www.picsearch. com). Für die Foto-Indizierung verwenden Suchmaschinen normalerweise den Text auf der Web-Seite, auf der sich auch das betreffende Bild befindet. Dabei werden doppelte Fundstellen automatisch aussortiert und Bilder mit der höchsten Qualität an den Anfang der Ergebnisliste gestellt. In Google sind laut Betreiber derzeit 880 Millionen Grafiken registriert. Zum Bildersuchdienst gelangen Sie auf der Google-Startseite per Klick auf die Registerkarte "Bilder". Geben Sie einen oder mehrere Suchbegriffe - durch Leerzeichen getrennt - in das Suchfeld ein, und klicken Sie auf den Button "Google Suche". Die Fundstellenanzeige erfolgt in Form von Miniaturvorschaubildern. Ein Klick auf das gewünschte Motiv öffnet die Website mit dem Foto. Um eine Grafik auf Ihrer Festplatte abzuspeichern, klicken Sie mit der rechten Maustaste darauf und wählen anschlie ßend im Kontextmenü den Befehl "Bild speichern unter". Lizenzfreie Bilder oder ganze Online-Fotogalerien stöbern Sie auch ohne spezielle Bildersuchfunktion mit einer Standardrecherche in einer Suchmaschine wie Alltheweb (www.alltheweb.com) auf. Geben Sie dazu einen Begriff wie "Foto", "Bilder" oder "Picture" in Kombination mit "lizenzfrei" oder "royalty-free" in das Suchfeld der verwendeten Suchmaschine ein.

    Abstract
    Die deutschen Suchmaschinen, Abacho, Acoon, Fireball und Lycos sowie die Web-Kataloge Web.de und Yahoo! werden einem Qualitätstest nach relativem Recall, Precision und Availability unterzogen. Die Methoden der Retrievaltests werden vorgestellt. Im Durchschnitt werden bei einem Cut-Off-Wert von 25 ein Recall von rund 22%, eine Precision von knapp 19% und eine Verfügbarkeit von 24% erreicht

    "Google forscht an einer neuen Version der Bildersuche. Zwei Wissenschaftler des Suchmaschinenbetreibers stellten auf der World-Wide-Web-Konferenz in Peking das neue Verfahren vor: Es kombiniert Bilderkennung und Googles Bewertungssystem "Page Rank". Das Rankingverfahren sorgt dafür, dass Google möglichst nur relevante Treffer anzeigt. Durch die geschickte Kombination beider Elemente hoffen die Forscher, jetzt deutlich bessere Bilder-Suchergebnisse zu erhalten. Die Wissenschaftler nutzen für ihr Projekt die 2.000 beliebtesten Google-Anfragen und verknüpfen diese Angaben mit der Bildersuche. Die Anzahl der unzutreffenden Bildfunde konnte durch dieses Verfahren um 83 Prozent gesenkt werden. INFO: www.google.de"
