Papers with Conversational Recommendation System
Improving Conversational Recommendation Systems via Bias Analysis and Language-Model-Enhanced Data Augmentation (2023.findings-emnlp)
Copied to clipboard
| Challenge: | Conversational Recommendation System (CRS) is a rapidly growing research area, along with advancements in language modelling techniques. |
| Approach: | They propose to use a benchmark dataset to develop CRS models and address biases arising from feedback loop inherent in multi-turn interactions to enhance model performance while mitigating biase. |
| Outcome: | The proposed strategies improve on ReDial and TG-ReDial benchmark datasets and offer additional insights on addressing multiple newly formulated biases. |

| Challenge: | Existing methods to analyze filter bubbles in the static recommendation environment are unable to burst them during user interactions. |
| Approach: | They propose a paradigm to learn multi-grained user preferences during dynamic user-system interactions via natural language conversations to burst filter bubbles. |
| Outcome: | The proposed paradigm achieves state-of-the-art performance and the superior of bursting filter bubbles in the conversational recommendation system. |

Zujie Liang, Huang Hu, Can Xu, Jian Miao, Yingying He, Yining Chen, Xiubo Geng, Fan Liang, Daxin Jiang
| Challenge: | Recent advances in neural models have shown promising progress on this task, but key challenges remain . |
| Approach: | They propose a framework that can decouple dialogue generation from item recommendation . they use a response template generator and item selector to generate a responses template . |
| Outcome: | The proposed framework outperforms the state-of-the-art methods on the benchmark ReDial. |
Towards a Unified Conversational Recommendation System: Multi-task Learning via Contextualized Knowledge Distillation (2023.emnlp-main)
Copied to clipboard
| Challenge: | Existing models that use separate recommendation and dialogue modules produce inconsistent results . a multi-task learning model is proposed to bridge the gap between recommendation and generated responses . |
| Approach: | They propose a multi-task learning model that integrates knowledge from two teachers and selectively gates between them via Contextualized Knowledge Distillation. |
| Outcome: | The proposed model significantly improves recommendation performance while enhancing fluency and achieves comparable results in terms of diversity. |
