A Comprehensive Graph Framework for Question Answering with Mode-Seeking Preference Alignment

ACL 2025finding

Recent advancements in retrieval-augmented generation (RAG) have enhanced large language models in question answering by integrating external knowledge. However, challenges persist in achieving global understanding and aligning responses with human ethical and quality preferences. To address these i…

Zero-shot Cross-lingual NER via Mitigating Language Difference: An Entity-aligned Translation Perspective

EMNLP 2025

Cross-lingual Named Entity Recognition (CL-NER) aims to transfer knowledge from high-resource languages to low-resource languages. However, existing zero-shot CL-NER (ZCL-NER) approaches primarily focus on Latin script language (LSL), where shared linguistic features facilitate effective knowledge t

Cross-domain NER with Generated Task-Oriented Knowledge: An Empirical Study from Information Density Perspective

EMNLP 2024main

Cross-domain Named Entity Recognition (CDNER) is crucial for Knowledge Graph (KG) construction and natural language processing (NLP), enabling learning from source to target domains with limited data. Previous studies often rely on manually collected entity-relevant sentences from the web or attempt…

One-Teacher and Multiple-Student Knowledge Distillation on Sentiment Classification

COLING 2022main

Knowledge distillation is an effective method to transfer knowledge from a large pre-trained teacher model to a compacted student model. However, in previous studies, the distilled student models are still large and remain impractical in highly speed-sensitive systems (e.g., an IR system). In this s…
