Mapping Technology Space by Normalizing Patent Networks
Jeff Alstott, Giorgio Triulzi, Bowen Yan +1
Technology is a complex system, with technologies relating to each other in a space that can be mapped as a network. The technology network's structure can reveal properties of tec…
Asymmetry in in-degree and out-degree distributions of large-scale industrial networks
Jianxi Luo, Daniel E. Whitney
Many natural, physical and social networks commonly exhibit power-law degree distributions. In this paper, we discover previously unreported asymmetrical patterns in the degree dis…
Loops and autonomy promote evolvability of ecosystem networks
Jianxi Luo
The structure of ecological networks, in particular food webs, determines their ability to evolve further, i.e. evolvability. The knowledge about how food web evolvability is deter…
Filtering Patent Maps for Visualization of Diversification Paths of Inventors and Organizations
Bowen Yan, Jianxi Luo
In the information science literature, recent studies have used patent databases and patent classification information to construct network maps of patent technology classes. In su…
Measuring Technological Distance for Patent Mapping
Bowen Yan, Jianxi Luo
Recent works in the information science literature have presented cases of using patent databases and patent classification information to construct network maps of technology fiel…
