Enhanced Multi-Channel Graph Convolutional Network for Aspect Sentiment Triplet Extraction

1 code implementation ACL 2022 Hao Chen, Zepeng Zhai, Fangxiang Feng, Ruifan Li, Xiaojie Wang

Specifically, we first define ten types of relations for ASTE task, and then adopt a biaffine attention module to embed these relations as an adjacent tensor between words in a sentence.

Concept Conductor: Orchestrating Multiple Personalized Concepts in Text-to-Image Synthesis

1 code implementation7 Aug 2024 Zebin Yao, Fangxiang Feng, Ruifan Li, Xiaojie Wang

Current methods struggle with attribute leakage and layout confusion when handling multiple concepts, leading to reduced concept fidelity and semantic consistency.

Dual Graph Convolutional Networks for Aspect-based Sentiment Analysis

1 code implementation ACL 2021 Ruifan Li, Hao Chen, Fangxiang Feng, Zhanyu Ma, Xiaojie Wang, Eduard Hovy

To overcome these challenges, in this paper, we propose a dual graph convolutional networks (DualGCN) model that considers the complementarity of syntax structures and semantic correlations simultaneously.
