Textgraphs@EMNLP-IJCNLP-2019 Shared Task Paper

This paper for the workshop Shared Task was accepted to the Textgraphs-13 workshop at EMNLP-IJCNLP-2019 in Hong Kong.


The TextGraphs-13 Shared Task on Explanation Regeneration asked participants to develop methods to reconstruct gold explanations for elementary science questions. Red Dragon AI's entries used the language of the questions and explanation text directly, rather than a constructing a separate graph-like representation. Our leaderboard submission placed us 3rd in the competition, but we present here three methods of increasing sophistication, each of which scored successively higher on the test set after the competition close.
