## 4 An Efficient Korean Embedding Model  
In this section, we aim to create an efficient Korean sentence embedding models by utilizing KLUE-RoBERTa-base, a pre-trained model based on a large Korean corpus. The pre-trained models are fine-tuned using the Korean datasets introduced in Section 3.1. We select different combinations of Korean datasets to train and evaluate our models, and the results are reported in Table 4. Additionally, we present the results of publicly available Korean SBERT models from Hugging Face and GitHub. The table presents accuracy as a percentage, where a value of 50.00 indicates that the corresponding model correctly \begin{table}
