Implicit Discourse Relation Recognition using Neural Tensor Network with Interactive Attention and Sparse Learning

no code implementations COLING 2018 Fengyu Guo, Ruifang He, Di Jin, Jianwu Dang, Longbiao Wang, Xiangang Li

In this paper, we propose a novel neural Tensor network framework with Interactive Attention and Sparse Learning (TIASL) for implicit discourse relation recognition.

A Semi-Supervised Stable Variational Network for Promoting Replier-Consistency in Dialogue Generation

no code implementations IJCNLP 2019 Jinxin Chang, Ruifang He, Longbiao Wang, Xiangyu Zhao, Ting Yang, Ruifang Wang

However, the sampled information from latent space usually becomes useless due to the KL divergence vanishing issue, and the highly abstractive global variables easily dilute the personal features of replier, leading to a non replier-specific response.

TransS-Driven Joint Learning Architecture for Implicit Discourse Relation Recognition

no code implementations ACL 2020 Ruifang He, Jian Wang, Fengyu Guo, Yugui Han

Implicit discourse relation recognition is a challenging task due to the lack of connectives as strong linguistic clues.

Aligning Recommendation and Conversation via Dual Imitation

no code implementations5 Nov 2022 Jinfeng Zhou, Bo wang, Minlie Huang, Dongming Zhao, Kun Huang, Ruifang He, Yuexian Hou

Human conversations of recommendation naturally involve the shift of interests which can align the recommendation actions and conversation process to make accurate recommendations with rich explanations.

Enhancing Personalized Dialogue Generation with Contrastive Latent Variables: Combining Sparse and Dense Persona

1 code implementation19 May 2023 Yihong Tang, Bo wang, Miao Fang, Dongming Zhao, Kun Huang, Ruifang He, Yuexian Hou

We design a Contrastive Latent Variable-based model (CLV) that clusters the dense persona descriptions into sparse categories, which are combined with the history query to generate personalized responses.

Mind vs. Mouth: On Measuring Re-judge Inconsistency of Social Bias in Large Language Models

no code implementations24 Aug 2023 Yachao Zhao, Bo wang, Dongming Zhao, Kun Huang, Yan Wang, Ruifang He, Yuexian Hou

We propose that this re-judge inconsistency can be similar to the inconsistency between human's unaware implicit social bias and their aware explicit social bias.

Infusing Hierarchical Guidance into Prompt Tuning: A Parameter-Efficient Framework for Multi-level Implicit Discourse Relation Recognition

1 code implementation23 Feb 2024 Haodong Zhao, Ruifang He, Mengnan Xiao, Jing Xu

First, we leverage parameter-efficient prompt tuning to drive the inputted arguments to match the pre-trained space and realize the approximation with few parameters.

CRFR: Improving Conversational Recommender Systems via Flexible Fragments Reasoning on Knowledge Graphs

no code implementations EMNLP 2021 Jinfeng Zhou, Bo wang, Ruifang He, Yuexian Hou

Although paths of user interests shift in knowledge graphs (KGs) can benefit conversational recommender systems (CRS), explicit reasoning on KGs has not been well considered in CRS, due to the complex of high-order and incomplete paths.

TopKG: Target-oriented Dialog via Global Planning on Knowledge Graph

no code implementations COLING 2022 Zhitong Yang, Bo wang, Jinfeng Zhou, Yue Tan, Dongming Zhao, Kun Huang, Ruifang He, Yuexian Hou

We design a global reinforcement learning with the planned paths to flexibly adjust the local response generation model towards the global target.
