snips-nlu ist eine Python-Bibliothek und eine Engine für Natural Language Understanding, die entwickelt wurde, um unstrukturierten Text in strukturierte Daten umzuwandeln. Sie identifiziert Benutzerabsichten (Intents) und extrahiert zugehörige Entitäten aus natürlichsprachlichen Sätzen, um eine maschinenlesbare Befehlsverarbeitung zu ermöglichen. Die Engine fungiert als mehrsprachiger Parser, der in der Lage ist, Text in mehreren Sprachen zu verarbeiten. Sie bildet identifizierte Entitäten auf kanonische Werte oder standardisierte ISO-Formate ab, wie z. B. Zeitstempel, um die Datenkonsistenz sicherzustellen. Das Projekt deckt Intent-Klassifizierung und Named Entity Recognition ab und nutzt Sequenz-Labeling und Tokenisierung, um Benutzerziele und spezifische Daten-Slots zu identifizieren.
