HAWK: Highlighting Entity-aware Knowledge for Alleviating Information Sparsity in Long Contexts

EMNLP 2025

As the textual data given as the context of various tasks lengthens, having necessary information scattered throughout makes it more difficult for large language models (LLMs) to capture relevant details. This challenge is particularly prominent in tasks such as question answering (QA), where key in

LimaCost: Data Valuation for Instruction Tuning of Large Language Models

EMNLP 2025

Instruction tuning (IT) is an effective approach for aligning large language models (LLMs) with human intentions. There is ongoing discourse regarding the data quality for IT. As an effort to find the robust criteria of data quality for IT, we introduce LimaCost, a data quality measure that exhibits

Semantic Inversion, Identical Replies: Revisiting Negation Blindness in Large Language Models

EMNLP 2025

Large language models (LLMs) often fail to capture semantic changes in queries due to negation, and generate incorrect responses. Negation frequently exists in the real world and is useful for understanding the opposite or absence of a statement, so it is an essential element in logical reasoning. P

Detecting Critical Errors Considering Cross-Cultural Factors in English-Korean Translation

COLING 2024main

Recent machine translation (MT) systems have overcome language barriers for a wide range of users, yet they still carry the risk of critical meaning deviation. Critical error detection (CED) is a task that identifies an inherent risk of catastrophic meaning distortions in the machine translation out…

PANDA: Persona Attributes Navigation for Detecting and Alleviating Overuse Problem in Large Language Models

EMNLP 2024main

In the persona-grounded dialogue (PGD) task, it is required not only to respond fluently, but also to ground the attributes according to the current conversation topic properly. However, due to their tendency to overly ground given attributes, LLMs often generate unnatural responses provoked by usin…

Search if you don’t know! Knowledge-Augmented Korean Grammatical Error Correction with Large Language Models

EMNLP 2024finding

Grammatical error correction (GEC) system is a practical task used in the real world, showing high achievements alongside the development of large language models (LLMs). However, these achievements have been primarily obtained in English, and there is a relative lack of performance for non-English…

Where am I? Large Language Models Wandering between Semantics and Structures in Long Contexts

EMNLP 2024main

As the utilization of Large Language Models (LLMs) becomes more widespread, there is a growing demand for their ability to handle more complex and longer external knowledge across various use cases. Most existing evaluations of the open-ended question answering (ODQA) task, which necessitates the us…

KEBAP: Korean Error Explainable Benchmark Dataset for ASR and Post-processing

EMNLP 2023long main

Automatic Speech Recognition (ASR) systems are instrumental across various applications, with their performance being critically tied to user satisfaction. Conventional evaluation metrics for ASR systems produce a singular aggregate score, which is insufficient for understanding specific system vuln…

A Dog Is Passing Over The Jet? A Text-Generation Dataset for Korean Commonsense Reasoning and Evaluation

NAACL 2022findings

Recent natural language understanding (NLU) research on the Korean language has been vigorously maturing with the advancements of pretrained language models and datasets. However, Korean pretrained language models still struggle to generate a short sentence with a given condition based on compositio…
