摘要：Based on Standard Literature Library of CNKI, opportunities for technical standards development are identified. The initial keywords of technical standard are determined based on LDA model, whose similar keywords are further confirmed by Word2Vec, and then combining LDA model with Word2Vec the representative keywords of technical standard of manufacturing industry are determined. According to confirmed representative keywords, the core technical standards of manufacturing industry are identified by using the center degree and “M-core” method. The dimensions of the frequency square matrix are reduced by using the PCA module of Python, and the scatter plot is brawn, the technology gaps are identified by combing the consideration on the core technical standards, and then the future development opportunities are confirmed based on the map of patent technology effect matrix.
