This study introduces a novel approach to creating a Korean-based knowledge graph by employing zero anaphora resolution, dependency parsing, and knowledge base extraction using ChatGPT. In order to overcome the limitations of conventional language models in handling the grammatical and morphological characteristics of Korean, this research incorporates prompt engineering techniques that combine zero anaphora resolution and dependency parsing. The main focus of this research is the 'Ko-Triple Extraction' method, which involves restoring omitted information in sentences and analyzing dependency structures to extract more sophisticated and accurate triple structures. The results demonstrate that this method greatly enhances the efficiency and accuracy of Korean text processing, and the validity of the triples has been confirmed through precision metrics. This study serves as fundamental research in the field of Korean text processing and suggests potential applications in various industries. Future research aims to apply this methodology to different industrial sectors and by expanding and connecting knowledge graph, generate valuable business insights. This approach is expected to contribute significantly make an important contribution not only to the advancement of natural language processing technologies but also to the effective of Korean in the field of artificial intelligence.
