Patent information-based analysis of EEG technology maturity and network analysis of EEG technology / 中华医学图书情报杂志

ABSTRACT

The life cycle, evolution and trend of EEG technology were studied by plotting its S curve model ac-cording to its maturity theory with Derwent Innovation Index Database-covered EEG technology patent data as a sample. Cluster analysis and strategic coordinate analysis according to the co-classification network of Derwent pa-tent classification code showed the linkage relationship and evolution trend in different fields of EEG technology. The frequency and centrality of EEG technology were analyzed according to the co-word network of Derwent manual code in order to identify the distribution and hotspots of research on EEG technology.
