Research on Early Patent Value Evaluation Method Integrating SAO Features
[Research purpose]In the context of the strategy of strengthening China through intellectual property rights,there is a dilem-ma that patent quantity increases but quality decreases,and technology transfer rate is low.Evaluating the value of early patents is of great significance for the cultivation of high-value patents and the transfer of patent technologies.[Research method]We propose an early pa-tent value assessment method that integrates features from the patent SAO(Subject-Action-Object)network and text.Firstly,we extract the SAO structures from patent abstracts and titles.Secondly,we employ social network analysis to identify the core components of the pa-tent SAO network and obtain centrality features.Next,we input the SAO structure sequence text into the Doc2Vec model to derive the pa-tent SAO text features.Finally,we combine the basic patent features with the SAO features to construct an early patent value assessment model based on the AutoGluon automated machine learning framework.[Research conclusion]Using patents in the field of artificial intel-ligence industry as an example,an empirical research is carried out.Experimental results demonstrate that the introduction of patent SAO fea-tures improves the accuracy,recall,and Fl score of the model by 2-5%compared to the baseline model,which confirms the effectiveness of patent SAO features in identifying early-stage high-value patents.
