Abstract:Since the innovation paths in the current technology opportunity identification are often abstract and vague, and in many cases require the participation of experts in the field of interpretation, the study builds a technology innovation path identification model based on text mining, machine learning algorithms, and multidimensional spatial patent maps, taking cold storage technology as an example. The technological innovation path identification method is proposed through, and multi-dimensional spatial patent map. Firstly, the technological innovation path identification framework is constructed to pre-process the relevant patent documents by word separation and cleaning and establish the knowledge map; secondly, the fused word frequency-inverse document frequency (TF-IDF) text mining method is used to extract keywords from patent documents, followed by the implicit Dirichlet distribution (LDA) algorithm to reduce the dimensionality of topic clustering and extract innovation dimensions; again, based on the target technical problem and the target Finally, the topology is used to calculate the comprehensive correlation degree of each innovation path. To reduce innovation cost, improve innovation efficiency, and provide decision-making references for enterprises to accurately carry out technological innovation and continuously improve their core competitiveness.
