Academic Evaluation

I participated a series of evaluation competitions holded by SemEval and several workshops colocated with ACL, EMNLP and NAACL. The name of our team is THU_NGN.

  • 1st EMNLP 2018 SMM4H Task 1&3
  • 1st NAACL metaphor Shared Task
  • 2nd SemEval-2018 Task 3
  • 1stIJCNLP-2017 Shared Task 2

My team achieved the 1st place in EMNLP 2018 SMM4H shared task 1 & 3, NAACL 2018 metaphor shared task, and the IJCNLP 2017 shared task 2. We achieved the 2nd place in SemEval task 3.
