{"pk":21594,"title":"Bi-Branch Meta-Learning for Few-Shot Word Sense Disambiguation","subtitle":null,"abstract":"Word Sense Disambiguation (WSD) has been a fundamental task for human language understanding. In specific contexts, a word may have different meanings. For rarely seen word senses, the disambiguation becomes challenging with limited examples. Meta-learning, as a widely adopted machine learning method for few-shot learning, addresses this by extracting metacognitive knowledge from training data, aiding models in \"learning to learn\". Hence, the advancement of meta-learning hinges on leveraging high-quality metacognitive knowledge. In light of this, we propose a Bi-Branch Meta-Learning method for WSD to enrich and accumulate metacognitive insights. Our method employs two branches during training and testing. During training, we use a bi-branch loss with original and augmented data from large language models to compensate for data scarcity. In testing, information from base classes generates bi-branch scores to refine predictions. Experiments show our method achieves a 74.3 F1 score in few-shot scenarios, demonstrating its potential for few-shot WSD.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Computer Science; Language understanding; Machine learning; Natural Language Processing; Neural Networks"}],"section":"Papers with Poster Presentation","is_remote":true,"remote_url":"https://escholarship.org/uc/item/0r56j71p","frozenauthors":[{"first_name":"Qingying","middle_name":"","last_name":"Chen","name_suffix":"","institution":"Tianjin University","department":""},{"first_name":"Jing","middle_name":"","last_name":"Zhang","name_suffix":"","institution":"Tianjin University","department":""},{"first_name":"Peng","middle_name":"","last_name":"Zhang","name_suffix":"","institution":"Tianjin University","department":""},{"first_name":"Hui","middle_name":"","last_name":"Gao","name_suffix":"","institution":"Tianjin University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2024-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/21594/galley/11193/download/"},{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/21594/galley/21987/download/"}]}
