AmpleHate: Amplifying the Attention for Versatile Implicit Hate Detection

EMNLP 2025

Implicit hate speech detection is challenging due to its subtlety and reliance on contextual interpretation rather than explicit offensive words. Current approaches rely on contrastive learning, which are shown to be effective on distinguishing hate and non-hate sentences. Humans, however, detect im

CodeComplex: Dataset for Worst-Case Time Complexity Prediction

EMNLP 2025

Reasoning ability of large language models (LLMs) is a crucial ability,especially in complex decision-making tasks. One significant task to show LLMs’reasoning capability is code time complexity prediction, which involves variousintricate factors such as the input range of variables and conditional

SuperST: Superficial Self-Training for Few-Shot Text Classification

COLING 2024main

In few-shot text classification, self-training is a popular tool in semi-supervised learning (SSL). It relies on pseudo-labels to expand data, which has demonstrated success. However, these pseudo-labels contain potential noise and provoke a risk of underfitting the decision boundary. While the pseu…

GDA: Grammar-based Data Augmentation for Text Classification using Slot Information

EMNLP 2023long findings

Recent studies propose various data augmentation approaches to resolve the low-resource problem in natural language processing tasks. Data augmentation is a successful solution to this problem and recent strategies give variation on sentence structures to boost performance. However, these approaches…

Boosting Code Summarization by Embedding Code Structures

COLING 2022main

Recent research on code summarization relies on the structural information from the abstract syntax tree (AST) of source codes. It is, however, questionable whether it is the most effective to use AST for expressing the structural information. We find that a program dependency graph (PDG) can repres…

Self-Training using Rules of Grammar for Few-Shot NLU

EMNLP 2021finding

We tackle the problem of self-training networks for NLU in low-resource environment—few labeled data and lots of unlabeled data. The effectiveness of self-training is a result of increasing the amount of training data while training. Yet it becomes less effective in low-resource settings due to unre…
