Defx at SemEval-2020 Task 6: Joint Extraction of Concepts and Relations for Definition Extraction
This work addresses definition extraction for knowledge acquisition in NLP, but it is incremental as it builds on existing shared task frameworks.
The paper tackled the problem of jointly extracting definition concepts and their relations from an English textbook corpus, achieving competitive results in the SemEval-2020 Task 6 shared task.
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.
