KIT-19: A Comprehensive Korean Instruction Toolkit on 19 Tasks for Fine-Tuning Korean Large Language Models
Introduction
In the current landscape of language models, achieving high performance in Korean NLP tasks requires specialized instruction datasets tailored to the unique aspects of the Korean language. To address the scarcity of such datasets, we introduce KIT-19, a comprehensive Korean Instruction Toolkit that encompasses 19 distinct tasks for fine-tuning Korean Large Language Models (LLMs). Unlike existing datasets that largely rely on translated instructions or outputs from models like ChatGPT, KIT-19 is meticulously crafted to capture the nuances of Korean language and culture, offering a robust foundation for advancing Korean LLMs.
Overview of KIT-19 Datasets
KIT-19 amalgamates 19 existing open-source datasets, each converted into an instruction format to facilitate instruction tuning for Korean LLMs. Here's a brief overview of the datasets included in KIT-19:
| Task Category | Datasets Included |
|---|---|
| Hate Speech Detection | APEACH, UnSmile, HateScore |
| Boolean Question Answering (QA) | KoBEST_BoolQ |
| Natural Language Inference (NLI) | KoBEST_COPA, korNLI |
| Text Generation | KoBEST_HellaSwag, kowiki_text |
| Semantic Textual Similarity (STS) | korSTS, pawsx_paraphr, ParaKQC, KoBEST_WIC, Style_KQC, Question_Pair |
| Sentiment Analysis (SA) | NSMC |
| Intent Argument Extraction | sae4k_sum, petitions_archive |
| Math | math_korean |
| Closed Book QA | kowiki_text (utilized differently for Closed Book QA and Text Generation) |
| Summarization | lbox_summarization |
Each dataset is selected and formated to ensure a wide coverage of tasks and scenarios relevant to the Korean language, making KIT-19 an exhaustive resource for developing and fine-tuning Korean LLMs.
Fine-Tuned Models
To demonstrate the effectiveness of KIT-19, we have fine-tuned representative Korean Pretrained LLMs, including Polyglot-Ko-5.8b and Polyglot-Ko-1.3b. The fine-tuned models showcase significant performance improvements across a variety of benchmark datasets:
- KoBEST_COPA
- KoBEST_BoolQ
- KoBEST_HellaSwag
- KLUE_STS
- KoBEST_SentiNeg
- KLUE_YNAT
The experimental results affirm that models trained with KIT-19 significantly outperform existing Korean LLMs, highlighting the potency and necessity of instruction datasets crafted specifically for the Korean language.
