A Neural Network for Open Information Extraction from German Text i

Master

Systems that extract information from natural language texts usually need to consider language-dependent aspects like vocabulary and grammar. Compared to the development of individual systems for different languages, development of multilingual information extraction (IE) systems has the potential to reduce cost and effort. One path towards IE from different languages is to port an IE system from one language to another. PropsDE is an open IE (OIE) system that has been ported from the English system PropS to the German language. There are only few OIE methods for German available. Our goal is to develop a neural network that mimics the rules of an existing rule-based OIE system. For that, we need to learn about OIE from German text. By performing an analysis and a comparison of the rule-based systems PropS and PropsDE, we can observe a step towards multilinguality, and we learn about German OIE. Then we present a deep-learning based OIE system for German, which mimics the behaviour of PropsDE. The precision in directly imitating PropsDE is 28.1%. Our model produces many extractions that appear promising, but are not fully correct.
