CATE: A Contrastive Pre-trained Model for Metaphor Detection with Semi-supervised Learning

no code implementations EMNLP 2021 Zhenxi Lin, Qianli Ma, Jiangyue Yan, Jieyu Chen

Metaphors are ubiquitous in natural language, and detecting them requires contextual reasoning about whether a semantic incongruence actually exists.

Multi-perspective Improvement of Knowledge Graph Completion with Large Language Models

1 code implementation4 Mar 2024 Derong Xu, Ziheng Zhang, Zhenxi Lin, Xian Wu, Zhihong Zhu, Tong Xu, Xiangyu Zhao, Yefeng Zheng, Enhong Chen

Knowledge graph completion (KGC) is a widely used method to tackle incompleteness in knowledge graphs (KGs) by making predictions for missing links.

Perturbation-based Self-supervised Attention for Attention Bias in Text Classification

no code implementations25 May 2023 Huawen Feng, Zhenxi Lin, Qianli Ma

In text classification, the traditional attention mechanisms usually focus too much on frequent words, and need extensive labeled data in order to learn.

Multi-modal Contrastive Representation Learning for Entity Alignment

1 code implementation COLING 2022 Zhenxi Lin, Ziheng Zhang, Meng Wang, Yinghui Shi, Xian Wu, Yefeng Zheng

Multi-modal entity alignment aims to identify equivalent entities between two different multi-modal knowledge graphs, which consist of structural triples and images associated with entities.
