OPI at SemEval 2023 Task 1: Image-Text Embeddings and Multimodal Information Retrieval for Visual Word Sense Disambiguation
This work addresses a challenging multimodal problem for NLP and computer vision researchers, but it is incremental as it builds on existing models like CLIP.
The paper tackled visual word sense disambiguation by integrating multimodal embeddings, learning to rank, and knowledge-based approaches, achieving third place in the multilingual task and first in the Persian subtask.
The goal of visual word sense disambiguation is to find the image that best matches the provided description of the word's meaning. It is a challenging problem, requiring approaches that combine language and image understanding. In this paper, we present our submission to SemEval 2023 visual word sense disambiguation shared task. The proposed system integrates multimodal embeddings, learning to rank methods, and knowledge-based approaches. We build a classifier based on the CLIP model, whose results are enriched with additional information retrieved from Wikipedia and lexical databases. Our solution was ranked third in the multilingual task and won in the Persian track, one of the three language subtasks.
