Abstract

Moderne Suchmaschinentechnologie soll in Zukunft die heterogenen wissenschaftlichen Fachdatenbanken zusammenführen und durch den Aufbau eines Suchmaschinen-Clusters den integrierten Zugriff auf das Deep Web erlauben. Das hbz hat den technischen Betrieb des vascoda-Portals übernommen und entwickelt das System zu einer offenen und innovativen Informationsplattform weiter. Auf dem 95. Deutschen Bibliothekartags in Dresden stellt das hbz den Einsatz der Suchmaschinentechnologie vor: beim Dreiländerkatalog - 30 Mio. Titel der deutschsprachigen wissenschaftlichen Literatur sind bereits sekundenschnell abrufbar - und bei vascoda, dem Internetportal für wissenschaftliche Information. Die Anreicherung von Katalogen mit Digitalmedien ist Aufgabe des hbz-Medienservers. Er hilft seinen Nutzern, alle Arten von Mediendateien (Text, Bild, Audio, Video) zu speichern, zu verwalten und benutzerfreundlich und langfristig im Web anzubieten. Hinzu kommen weitere Schwerpunkte wie Scan-Projekte und der Nachweis elektronischer Pflichtexemplare.
