Abstract:

The study constructs a prediction model for university patent transfers and explores the characteristic variables that affect the predictive accuracy to improve the patent conversion rate of Chinese universities. After cleaning and standardizing the patent fields, the study uses LDA, SBERT, and SBERT-LDA to extract the patent technology topics. The impact of these topic extraction models on the prediction performance is compared. Additionally, six commonly used classification algorithms are evaluated on accuracy, precision, recall, and F1 score. The experimental results show that in the field of blockchain technology, the random forest algorithm combined with the SBERT-LDA topic extraction method achieves the best prediction performance. Furthermore, the SHAP framework is employed to analyze the characteristic variables affecting model performance. These characteristic variables can be divided into four types: dichotomy, positive correlation, negative correlation, and random fluctuation.
