Yi Luan, Mari Ostendorf, Hannaneh Hajishirzi · 2018
This paper describes our submission for the SemEval 2018 Task 7 shared task on semantic relation extraction and classification in scientific papers.We extend the end-to-end relation extraction model of (Miwa and Bansal, 2016) with enhancements such as a characterlevel encoding attention mechanism on selecting pretrained concept candidate embeddings.Our official submission ranked the second in relation classification task (Subtask 1.1 and Subtask 2 Senerio 2), and the first in the relation extraction task (Subtask 2 Scenario 1).
