Innovation Networks: Emerging Technological Trajectories on Ethanol Fermentation Processes.
Silveira, Jose Maria
Three methodological approaches – throught patents
* According to OTTE & ROUSSEAU, 2002, based on graph theory literature
Centrality (indegree): 0,0119191
Not tipical of innovation net. This is the same net of the last slide. Density does not changes, despite GD = 1,0.
Low relationships variance.
No tech trajectory defined.
No pattern of highly cited and highly connected nodes.
Innovation is a star war for SSF.
