SalesBot: Transitioning from Chit-Chat to Task-Oriented Dialogues
Ssu Chiu, Maolin Li, Yen-Ting Lin +1
Dialogue systems are usually categorized into two types, open-domain and task-oriented. The first one focuses on chatting with users and making them engage in the conversations, wh…
BARCOR: Towards A Unified Framework for Conversational Recommendation Systems
Ting-Chun Wang, Shang-Yu Su, Yun-Nung Chen
Recommendation systems focus on helping users find items of interest in the situations of information overload, where users' preferences are typically estimated by the past observe…
Adapting Pretrained Transformer to Lattices for Spoken Language Understanding
Chao-Wei Huang, Yun-Nung Chen
Lattices are compact representations that encode multiple hypotheses, such as speech recognition results or different word segmentations. It is shown that encoding lattices as oppo…
Tree Transformer: Integrating Tree Structures into Self-Attention
Yau-Shian Wang, Hung-Yi Lee, Yun-Nung Chen
Pre-training Transformer from large-scale raw texts and fine-tuning on the desired task have achieved state-of-the-art results on diverse NLP tasks. However, it is unclear what the…
Towards Understanding of Medical Randomized Controlled Trials by Conclusion Generation
Alexander Te-Wei Shieh, Yung-Sung Chuang, Shang-Yu Su +1
Randomized controlled trials (RCTs) represent the paramount evidence of clinical medicine. Using machines to interpret the massive amount of RCTs has the potential of aiding clinic…
DyKgChat: Benchmarking Dialogue Generation Grounding on Dynamic Knowledge Graphs
Yi-Lin Tuan, Yun-Nung Chen, Hung-yi Lee
Data-driven, knowledge-grounded neural conversation models are capable of generating more informative responses. However, these models have not yet demonstrated that they can zero-…
Learning ASR-Robust Contextualized Embeddings for Spoken Language Understanding
