Research on Identification Methods of Technological Innovation Elements and Their Associations:A Case Study on Synthetic Biology
[Purpose/Significance]Technological innovation can be regarded as a complex systematic project involving the synergistic effect of multiple technological innovation elements.Extracting technological innovation elements and their associations from technical texts,analyzing their temporal dynamic changes and cross-domain in-teractions can reveal the process and law of technological innovation at the micro level,and then predict innovation opportunities.One of the key issues is how to identify technological innovation elements and their associations from technical texts.Specifically,this includes what technological innovation elements and their associations are to be iden-tified and what methods are used for identification.[Method/Process]In order to solve the problem of object identifi-cation,the authors previously constructed a conceptual model of elemental associations oriented to the description of the technological innovation process.In order to solve the problem of identification method,this paper took the field of synthetic biology as an example,oriented to the text features of the elements and their associations in the conceptual model,and proposed a method for identifying the technological innovation elements and their associations.Based on patents and supplemented by papers,the method synthesized by textual content mining and citation analysis.which It revealed the interactions between technological innovation elements originated from the same or different fields in the technological innovation process,as well as the role of different technological innovation elements in different techno-logical innovation events.[Result/Conclusion]Applying the identification framework to the field of synthetic biology,it identifies 7 633 technical object elements,3 420 technical method elements,3 919 technical application elements,5 393 technical theory elements and their domain and time attributes,as well as 25 647 associative relationships of six different elements in 6 435 patents and their associated papers.This method can lay the foundation for revealing the process of technological innovation based on elemental correlation,analyzing the process and law of technological in-novation in frontier cross-cutting fields,and predicting the opportunities of convergent innovation.
