Fine-tuned KoR-SRoBERTa for Corporate News Relevance Classification

⸻

Overview

This model is a fine-tuned version of the base model jhgan/ko-sroberta-multitask, adapted specifically for relevance classification of Korean corporate-related news articles. The goal of this model is to improve performance in distinguishing significant news within firm-specific news contexts, which often contain domain-specific financial language.

This work is based on the methodology and dataset presented in the following academic paper:
