Defx at SemEval-2020 Task 6: Joint Extraction of Concepts and Relations for Definition Extraction

Marc Hübner, Christoph Alt, Robert Schwarzenberg, Leonhard Hennig


Abstract
Definition Extraction systems are a valuable knowledge source for both humans and algorithms. In this paper we describe our submissions to the DeftEval shared task (SemEval-2020 Task 6), which is evaluated on an English textbook corpus. We provide a detailed explanation of our system for the joint extraction of definition concepts and the relations among them. Furthermore we provide an ablation study of our model variations and describe the results of an error analysis.
