SU-NLP at SemEval-2022 Task 11: Complex Named Entity Recognition with Entity Linking

This paper describes the system proposed by Sabanci University Natural Language Processing Group in the SemEval-2022 MultiCoNER task. We developed an unsupervised entity linking pipeline that detects potential entity mentions with the help of Wikipedia and also uses the corresponding Wikipedia context to help the classifier in finding the named entity type of that mention. The proposed pipeline significantly improved the performance, especially for complex entities in low-context settings.
