Abstract

In this paper, we present a system for detecting complex named entities in multilingual and code-mix settings. We discuss the results obtained in task 11 (MultiCoNER) of the SemEval 2022 competition. The model is an ensemble of various transformer-based language models combined with a Conditional Random Field (CRF) layer. Our model ranks fourth in track 12 (multilingual track) and fifth in track 13 (code-mixed track). We describe the details of our model implementation and discuss the effect of different aggregation methods. Finally, we conduct additional analyses to understand the performance differences between languages.
