FINKRX: Establishing Best Practices for Korean Financial NLP
Guijin Son | Hyunwoo Ko | Hanearl Jung | Chami Hwang
Proceedings of the 63rd Annual Meeting of the Association for Computational Linguistics (Volume 6: Industry Track)

In this work, we present the first open leaderboard for evaluating Korean large language models focused on finance. Operated for abouteight weeks, the leaderboard evaluated 1,119 submissions on a closed benchmark covering five MCQA categories: finance and accounting, stock price prediction, domestic company analysis, financial markets, and financial agent tasks and one open-ended qa task. Building on insights from these evaluations, we release an open instruction dataset of 80k instances and summarize widely used training strategies observed among top-performing models. Finally, we introduce FINKRX, a fully open and transparent LLM built using these best practices. We hope our contributions help advance the development of better and safer financial LLMs for Korean and other languages.

KRX Bench: Automating Financial Benchmark Creation via Large Language Models
Guijin Son | Hyunjun Jeon | Chami Hwang | Hanearl Jung
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

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.
