Graph annotations in modeling complex network topologies
2009
ACM Transactions on Modeling and Computer Simulation

We introduce a network topology modeling framework that treats annotations as an extended correlation profile of a network. ...
In this work, we abstract such additional information as network annotations. ...
CONCLUSIONS In this work, we have focused on the problem of generating synthetic annotated graphs that model real complex net- works. ...
