Psychology-guided Controllable Story Generation

no code implementations COLING 2022 Yuqiang Xie, Yue Hu, Yunpeng Li, Guanqun Bi, Luxi Xing, Wei Peng

Inspired by psychology theories, we introduce global psychological state chains, which include the needs and emotions of the protagonists, to help a story generation system create more controllable and well-planned stories.

Do You Know My Emotion? Emotion-Aware Strategy Recognition towards a Persuasive Dialogue System

1 code implementation24 Jun 2022 Wei Peng, Yue Hu, Luxi Xing, Yuqiang Xie, Yajing Sun

Specifically, CFO-Net designs a feedback memory module, including strategy pool and feedback pool, to obtain emotion-aware strategy representation.

Control Globally, Understand Locally: A Global-to-Local Hierarchical Graph Network for Emotional Support Conversation

1 code implementation27 Apr 2022 Wei Peng, Yue Hu, Luxi Xing, Yuqiang Xie, Yajing Sun, Yunpeng Li

Emotional support conversation aims at reducing the emotional distress of the help-seeker, which is a new and challenging task.

Multi-CPR: A Multi Domain Chinese Dataset for Passage Retrieval

1 code implementation7 Mar 2022 Dingkun Long, Qiong Gao, Kuan Zou, Guangwei Xu, Pengjun Xie, Ruijie Guo, Jian Xu, Guanjun Jiang, Luxi Xing, Ping Yang

We find that the performance of retrieval models trained on dataset from general domain will inevitably decrease on specific domain.

CLSEG: Contrastive Learning of Story Ending Generation

1 code implementation18 Feb 2022 Yuqiang Xie, Yue Hu, Luxi Xing, Yunpeng Li, Wei Peng, Ping Guo

To address these two issues, we propose a novel Contrastive Learning framework for Story Ending Generation (CLSEG), which has two steps: multi-aspect sampling and story-specific contrastive learning.

Coarse-to-Careful: Seeking Semantic-related Knowledge for Open-domain Commonsense Question Answering

no code implementations4 Jul 2021 Luxi Xing, Yue Hu, Jing Yu, Yuqiang Xie, Wei Peng

It is prevalent to utilize external knowledge to help machine answer questions that need background commonsense, which faces a problem that unlimited knowledge will transmit noisy and misleading information.

MCR-Net: A Multi-Step Co-Interactive Relation Network for Unanswerable Questions on Machine Reading Comprehension

no code implementations8 Mar 2021 Wei Peng, Yue Hu, Jing Yu, Luxi Xing, Yuqiang Xie, Zihao Zhu, Yajing Sun

Most of the existing systems design a simple classifier to determine answerability implicitly without explicitly modeling mutual interaction and relation between the question and passage, leading to the poor performance for determining the unanswerable questions.

Uncertainty-Aware Semantic Augmentation for Neural Machine Translation

no code implementations EMNLP 2020 Xiangpeng Wei, Heng Yu, Yue Hu, Rongxiang Weng, Luxi Xing, Weihua Luo

As a sequence-to-sequence generation task, neural machine translation (NMT) naturally contains intrinsic uncertainty, where a single sentence in one language has multiple valid counterparts in the other.

On Learning Universal Representations Across Languages

no code implementations ICLR 2021 Xiangpeng Wei, Rongxiang Weng, Yue Hu, Luxi Xing, Heng Yu, Weihua Luo

Recent studies have demonstrated the overwhelming advantage of cross-lingual pre-trained models (PTMs), such as multilingual BERT and XLM, on cross-lingual NLP tasks.

Unsupervised Neural Machine Translation with Future Rewarding

no code implementations CONLL 2019 Xiangpeng Wei, Yue Hu, Luxi Xing, Li Gao

In this paper, we alleviate the local optimality of back-translation by learning a policy (takes the form of an encoder-decoder and is defined by its parameters) with future rewarding under the reinforcement learning framework, which aims to optimize the global word predictions for unsupervised neural machine translation.
