Abstract

Text und Data Mining sind ein Bündel von Technologien, die eng mit den Themenfeldern Statistik, Maschinelles Lernen und dem Erkennen von Mustern verbunden sind. Die üblichen Definitionen beziehen eine Vielzahl von verschiedenen Verfahren mit ein, ohne eine exakte Grenze zu ziehen. Data Mining bezeichnet die Suche nach Mustern, Regelmäßigkeiten oder Auffälligkeiten in stark strukturierten und vor allem numerischen Daten. "Any algorithm that enumerates patterns from, or fits models to, data is a data mining algorithm." Numerische Daten und Datenbankinhalte werden als strukturierte Daten bezeichnet. Dagegen gelten Textdokumente in natürlicher Sprache als unstrukturierte Daten.
