The workshop will have a challenge (shared task) on evaluating contextualized word representations called Word-in-Context (WiC). The task is based on the WiC dataset (https://pilehvar.github.io/wic/, NAACL 2019) and targets different areas of lexical semantics including, but not limited to, sense representation, word sense disambiguation, and contextualised word embeddings. Training, development and test data will be provided for the participants. More information about the challenge and how to participate can be found at https://competitions.codalab.org/competitions/20010. Important dates are shown below.
