Augenstein and Søgaard (2017) use a multi-task learning strategy to improve the performance of supervised keyphrase classification, but they only report dev set performance on SemEval Task 10, we also include their result here and refer it as MULTITASK.
we observe that ULM+GRAPHFEAT* can greatly reduce the confusion, with 3.5% relative improvement of PRO-CESS and 3.6% relative improvement of PROCESS over ULM+GRAPHINTERP on token level.
