Abstract Accurately identifying innovation technology opportunities in massive patent information is a key measure to reduce corporate innovation risk. This study relies on the multidimensional map of technology innovation to build a path for identifying innovation technology opportunities. First, we use the Latent Dirichlet Allocation (LDA) algorithm to extract technical elements and topics from many patent documents. Second, we navigate and classify technical innovation elements combined with the multidimensional map of technology innovation, and then explore multiple potential technological innovation paths and multiple innovation rules. Third, the TextRank-IDF novelty evaluation index is proposed to sort the innovation opportunities to identify innovation paths with a higher value. Finally, the technical innovation of submersible motors is considered as an example to verify the technology opportunity discovery path's effectiveness. The results show that the technological innovation path under the massive patent information constructed in this study can provide a useful reference for companies to choose innovation schemes and continuously improve innovation efficiency scientifically.
