Knowledge flows from science to AI technology: Identifying core and brokerage technological roles
Table 2
Top 10 main group CPCs by centrality in network analysis (10-year periods). This table presents the top ten main-group CPC codes for each ten-year period of AI patent filings, identified through CPC co-occurrence network analysis and ranked by weighted degree centrality and betweenness centrality. Weighted degree centrality reflects the extent to which a CPC connects to other CPCs and indicates its role as a core technology, while betweenness centrality captures its brokerage technology in bridging distinct technological domains.
