Bei der Informationsextraktion (IE) geht es um die automatische Extraktion von Information aus Volltexten. Die Anwendungen erstrecken sich von der Unterstützung von Internet-Suchmaschinen bis hin zum automatischen Aufbau von Fachdatenbanken. Die Methoden reichen von der Analyse natürlicher Sprache über automatische Termerkennung bis zu automatischen Lernverfahren, wobei symbolische, statistische und hybride Methoden zum Einsatz kommen. Komplexe Informationsstrukturen können mit sogenannten Templates (Informationsmustern) repräsentiert werden. In der Veranstaltung werden verschiedene Anwendungen und Methoden für diverse Anwendungsdomänen betrachtet.
Inhalte:
Das Seminar behandelt Ansätze, Verfahren und Werkzeuge der Informationsextraktion und legt einen besonderen Fokus auf die Erkennung von Eigennamen und von domänen- bzw. fachspezifischer Information. Auch sollen Fragestellungen der Evaluation derartiger Verfahren diskutiert werden.
Lernziele:
Die Teilnehmer sollen lernen, wie sie Ressourcen für IE Systeme bewerten können. Außerdem sollen sie befähigt werden, dass sie bei der Entwicklung, beim Einsatz und bei der Bewertung von IE-Systemen mitwirken können.
