Large language models (LLMs) trained on massive corpora demonstrate impressive capabilities in a wide range of tasks. While there are ongoing efforts to adapt these models to languages beyond English, the attention given to their evaluation methodologies remains limited. Current multilingual benchmarks often rely on back translations or re-implementations of English tests, limiting their capacity to capture unique cultural and linguistic nuances. To bridge this gap for the Korean language, we introduce the HAE-RAE Bench, a dataset curated to challenge models lacking Korean cultural and contextual depth. The dataset encompasses six downstream tasks across four domains: vocabulary, history, general knowledge, and reading comprehension. Unlike traditional evaluation suites focused on token and sequence classification or mathematical and logical reasoning, the HAE-RAE Bench emphasizes a model’s aptitude for recalling Korean-specific knowledge and cultural contexts. Comparative analysis with prior Korean benchmarks indicates that the HAE-RAE Bench presents a greater challenge to non-Korean models by disturbing abilities and knowledge learned from English being transferred.

Proceedings of the Joint Workshop of the 7th Financial Technology and Natural Language Processing, the 5th Knowledge Discovery from Unstructured Data in Financial Services, and the 4th Workshop on Economics and Natural Language Processing @ LREC-COLING 2024

In this work, we introduce KRX-Bench, an automated pipeline for creating financial benchmarks via GPT-4. To demonstrate the effectiveness of the pipeline, we create KRX-Bench-POC, a benchmark assessing the knowledge of LLMs in real-world companies. This dataset comprises 1,002 questions, each focusing on companies across the U.S., Japanese, and Korean stock markets. We make our pipeline and dataset publicly available and integrate the evaluation code into EleutherAI’s Language Model Evaluation Harness.

ESG Classification by Implicit Rule Learning via GPT-4

Proceedings of the Joint Workshop of the 7th Financial Technology and Natural Language Processing, the 5th Knowledge Discovery from Unstructured Data in Financial Services, and the 4th Workshop on Economics and Natural Language Processing @ LREC-COLING 2024

In this work, we adopt multiple prompting, chain-of-thought reasoning, and in-context learning strategies to guide GPT-4 in solving ESG classification tasks. We rank second in the Korean subset for Shared Task ML-ESG-3 in Impact Type prediction. Furthermore, we adopt open models to explain their calibration and robustness to different prompting strategies. The longer general pre-training correlates with enhanced performance in financial downstream tasks.
