Negation Triplet Extraction with Syntactic Dependency and Semantic Consistency

1 code implementation15 Apr 2024 Yuchen Shi, Deqing Yang, Jingping Liu, Yanghua Xiao, ZongYu Wang, Huimin Xu

To achieve NTE, we devise a novel Syntax&Semantic-Enhanced Negation Extraction model, namely SSENE, which is built based on a generative pretrained language model (PLM) {of Encoder-Decoder architecture} with a multi-task learning framework.

Don't Forget Your Reward Values: Language Model Alignment via Value-based Calibration

1 code implementation25 Feb 2024 Xin Mao, Feng-Lin Li, Huimin Xu, Wei zhang, Anh Tuan Luu

While Reinforcement Learning from Human Feedback (RLHF) significantly enhances the generation quality of Large Language Models (LLMs), recent studies have raised concerns regarding the complexity and instability associated with the Proximal Policy Optimization (PPO) algorithm, proposing a series of order-based calibration methods as viable alternatives.

MRAEA: An Efficient and Robust Entity Alignment Approach for Cross-lingual Knowledge Graph

1 code implementation The International Conference on Web Search and Data Mining (WSDM) 2020 Xin Mao, Wenting Wang, Huimin Xu, Man Lan, Yuanbin Wu

To tackle these challenges, we propose a novel Meta Relation Aware Entity Alignment (MRAEA) to directly model cross-lingual entity embeddings by attending over the node's incoming and outgoing neighbors and its connected relations' meta semantics.
