Improving Factual Consistency in Abstractive Summarization with Sentence Structure Pruning

COLING 2024main

State-of-the-art abstractive summarization models still suffer from the content contradiction between the summaries and the input text, which is referred to as the factual inconsistency problem. Recently, a large number of works have also been proposed to evaluate factual consistency or improve it b…

Zero-Shot Spoken Language Understanding via Large Language Models: A Preliminary Study

COLING 2024main

Zero-shot Spoken Language Understanding (SLU) aims to enable task-oriented dialogue systems to understand user needs without training data. Challenging but worthwhile, zero-shot SLU reduces the time and effort that data labeling takes. Recent advancements in large language models (LLMs), such as GPT…

Enhancing Code-Switching for Cross-lingual SLU: A Unified View of Semantic and Grammatical Coherence

EMNLP 2023short main

Despite the success of spoken language understanding (SLU) in high-resource languages, achieving similar performance in low-resource settings, such as zero-shot scenarios, remains challenging due to limited labeled training data. To improve zero-shot cross-lingual SLU, recent studies have explored c…

MCLF: A Multi-grained Contrastive Learning Framework for ASR-robust Spoken Language Understanding

EMNLP 2023long findings

Enhancing the robustness towards Automatic Speech Recognition (ASR) errors is of great importance for Spoken Language Understanding (SLU). Trending ASR-robust SLU systems have witnessed impressive improvements through global contrastive learning. However, although most ASR errors occur only at local…

Towards Unified Spoken Language Understanding Decoding via Label-aware Compact Linguistics Representations

ACL 2023findings

Joint intent detection and slot filling models have shown promising success in recent years due to the high correlations between the two tasks. However, previous works independently decode the two tasks, which could result in misaligned predictions for both tasks. To address this shortcoming, we pro…

LiteVL: Efficient Video-Language Learning with Enhanced Spatial-Temporal Modeling

EMNLP 2022main

Recent large-scale video-language pre-trained models have shown appealing performance on various downstream tasks. However, the pre-training process is computationally expensive due to the requirement of millions of video-text pairs and the redundant data structure of each video. To mitigate these p…

Towards Joint Intent Detection and Slot Filling via Higher-order Attention

IJCAI 2022poster

Recently, attention-based models for joint intent detection and slot filling have achieved state-of-the-art performance. However, we think the conventional attention can only capture the first-order feature interaction between two tasks and is insufficient. To address this issue, we propose a unifie…
