1. Parameter Updating for Digital Satellite Model via Data Mining Approach
   • Utilized text mining techniques to analyze the text similarity of the ontology-based satellite parameters obtained from web-crawled open-access journal articles.
   • Constructed a knowledge graph containing the satellite parameters and their similarity, correlation, and sensitivity
   • Updated digital satellite model parameters that are selected and grouped by utilizing graph reasoning and data mining algorithms
2. Satellite Collision Risk Analysis based on Data Mining

• Analyzed and predicted the collision risk of satellites by using data mining techniques, including clustering and classification, based on orbital data web-crawled from the CelesTrak website
• Developed a GUI to automate the entire analysis process and generate an analysis report
