Talk at Future Search Engines 2014 (FoRESEE), INFORMATIK2014 (http://www.informatik2014.de/) Abstract (DE): Die gezielte Suche von Informationen in großen Dokumentenmengen ist eine der wesentlichen Herausforderungen der heutigen Zeit. In diesem Papier wird beschrieben, wie wir die Analyse von und Suche in mehrsprachigen Kundenspezifikationen in einem aktuellen Kundenprojekt im Maschinenbau realisiert haben. Im Rahmen der Dokumentenanalyse kommen computerlinguistische und semantische Technologien zum Einsatz. Basis für die Suche bildet das Paradigma des Faceted Browsing.
