Research on the development trend prediction of steel material technology based on social perception analysis

Tracking technology hotspots, identifying technology market demands and predicting the future development prospects of technology are of great significance to the formulation of national strategies and the improvement of enterprises’ technological competitiveness. The research constructs an iron and steel material technology evolution trend prediction model embedded in social perception, and extracts and analyzes the perceptual information of iron and steel material technology from two aspects of perceptual semantic keywords and perceptual semantic correlation network. Iron and steel material technology presents two-dimensional evolution characteristics of horizontal basic technology-key core technology breakthrough-frontier technology integration and vertical basic research-technology application-marketization-industrialization. And from the material research, market level, and industry level, the future development hotspots and trend forecasts of steel materials are carried out.
