Zusammenfassung

Wir stellen eine Reihe von innovativen Methoden zur webbasierten multilingualen Fragebeantwortung in offenen Domänen vor. Insbesondere werden neuartige Strategien zur Bestimmung optimaler Antwortkontexte und zur Extraktion von exakten Antworten auf Basis von sprachunabhängigen, datengetriebenen maschinellen Lernverfahren beschrieben. Es werden zwei alternative Methoden für die crosslinguale Frageanalyse skizziert mit deren Hilfe für eine Anfrage in einer natürlichen Sprache Antworten in Dokumenten einer anderen natürlichen Sprache bestimmt werden können. Alle Methoden sind detailliert evaluiert und weisen eine vielversprechende Performanz auf.

Abstract

We present a series of innovative methods for a webbased multilingual question answering in open domains. In particular, we present novel strategies for the determination of optimal answer contexts and for the extraction of exact answers on the basis of language-independent, data-driven Machine Learning algorithms. Two alternative methods for the crosslingual question analysis are presented that are used for finding answers in documents of one natural language using a query formulated in another natural language. All methods are evaluated in detail and demonstrate a promising performance.
