LIAAD at SemDeep-5 Challenge: Word-in-Context (WiC)
This work addresses the problem of word sense detection in sentences for natural language processing, with incremental improvements in mitigating overfitting.
The paper tackled the Word-in-Context challenge by adapting a Word Sense Disambiguation system using contextual and sense embeddings, achieving second place in the competition and competitive performance without using provided training data.
This paper describes the LIAAD system that was ranked second place in the Word-in-Context challenge (WiC) featured in SemDeep-5. Our solution is based on a novel system for Word Sense Disambiguation (WSD) using contextual embeddings and full-inventory sense embeddings. We adapt this WSD system, in a straightforward manner, for the present task of detecting whether the same sense occurs in a pair of sentences. Additionally, we show that our solution is able to achieve competitive performance even without using the provided training or development sets, mitigating potential concerns related to task overfitting
