How can we understand the behaviour of networks? The relation between network structure and information processing capacity is essential. So far, a vast amount of data has been collected to understand the structure and functioning of networks. However, analysing these data can be challenging. The EU-funded SmartNets project aims to conduct research on networks and to use visualisation tools across three analysis dimensions: structure, activity and information processing. SmartNets will combine existing and novel techniques, from different types of research domains and across all three analysis dimensions. Ultimately, the project will provide new insights into the properties, behaviour and dynamic evolution of biological networks.
