Technology Element Extraction and Technology Opportunity Identification from Knowledge Element Perspective
[Research purpose]The extraction of technology elements and the analysis of technology opportunities based on the theory of knowledge elements are of great significance to the accurate prediction of technology opportunities and the efficient development of techno-logical innovation for enterprises.[Research method]Firstly,a deep learning based technology elemental extraction model and a seman-tic information based sub-technology identification method are constructed to acquire the existing technical knowledge;Secondly,technol-ogy opportunity identification using technology elemental knowledge networks with the help of link prediction and SVM algorithm.Final-ly,the validity of this research is verified with the example of water quality turbidity detection technology opportunity identification.[Re-search conclusion]The technological opportunity path identified by knowledge meta-theory in this paper not only expands the research scope of technological innovation theory,but also provides a scientific decision-making reference for enterprises to continuously improve innovation efficiency while reducing blind innovation risks.
