Seminar "Informationsorganisation und -suche mit XML"
Seminar |
Dr.-Ing.
Ralf Schenkel Lehrstuhl für Datenbanken und Informationssysteme |
Die Extended Markup Language XML findet heute als universelles Format für Datenspeicherung und Datenaustausch verbreitet Anwendung in vielen Bereichen, so dass immer mehr Daten als XML vorliegen. Die geschickte Speicherung und Organisation solcher Informationen, aber auch die Migration vorhandener, relationaler Datenbestände sind daher eine fundamentale Notwendigkeit für zukünftige Anwendungen. Daneben sind auch Mechanismen für eine effiziente und effektive Suche in XML-Dokumenten, aber auch im semantischen Web der Zukunft hochgradig aktuelle und wichtige Forschungsthemen.Das Seminar behandelt ausgewählte, spannende Forschungsarbeiten der international renommierten Konferenzen der letzten Jahre.
