SeaLLMs - Large Language Models for Southeast Asia

ACL 2024system demonstrations

Despite the remarkable achievements of large language models (LLMs) in various tasks, there remains a linguistic bias that favors high-resource languages, such as English, often at the expense of low-resource and regional languages. To address this imbalance, we introduce SeaLLMs, an innovative seri…

A Hierarchical Encoding-Decoding Scheme for Abstractive Multi-document Summarization

EMNLP 2023long findings

Pre-trained language models (PLMs) have achieved outstanding achievements in abstractive single-document summarization (SDS). However, such benefits may not fully extend to multi-document summarization (MDS), where the handling of cross-document information is more complex. Previous works either des…

MReD: A Meta-Review Dataset for Structure-Controllable Text Generation

ACL 2022findings

When directly using existing text generation datasets for controllable generation, we are facing the problem of not having the domain knowledge and thus the aspects that could be controlled are limited. A typical example is when using CNN/Daily Mail dataset for controllable text summarization, there…
