Visual Word Sense Disambiguation (VWSD) task aims to find the most related image among 10 images to an ambiguous word in some limited textual context.In this work, we use Alt-CLIP features and a 3-layer standard transformer encoder to compare the cosine similarity between the given phrase and different images.Also, we improve our model's generalization by using a subset of LAION-5B.The best official baseline achieves 37.20% and 54.39% macro-averaged hit rate and MRR (Mean Reciprocal Rank) respectively.Our best configuration reaches 39.61% and 56.78% macro-averaged hit rate and MRR respectively.The code will be made publicly available on GitHub.
