Abstract: “Regulatory compliance checking is crucial for power grid designs with respect to their safe operation.Traditional design checking depends greatly on the knowledge and experiences of human expert, and accordingly the manual checking is often tedious, time consuming and error prone.Recently, the application of Natural Language Processing (NLP) approach to extract information from design codes written in English leads to promising results. Unfortunately, the robustness of NLP-based information extraction approach should be furthered in order to analyze the textual codes written in Chinese. In this regard, GIM-CNL is developed as a controlled language for rewriting Chinese design code for power grid infrastructures. This study explores the difficulties in understanding design code written in Chinese. The framework of the GIM-CNL and the associated ontology of power grid engineering is also developed. Finally, an example of information extraction from the design codes is studied to demonstr”
