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.

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.

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.

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.
