Kivonat:

Network science has undergone a spectacular development over the last
decade for two main reasons: i) Information technology has made
available an unprecedented abundance of data; ii) the notions and
techniques of statistical physics have penetrated into network science.

Due to these components, social network theory is in the process of a
conceptual change from detailed, multi-property analysis of
questionnaire-based, limited-size networks to the investigation of
less diverse, sometimes huge, IT-based networks. In this talk Prof.
Kertész will present an example for the latter approach. He and his
colleagues analyse a mobile-phone-based network of about 7 million
users. They argue that using the records of phone conservations one
can map out a proxy for the network of human interactions at the
societal level and provide, for the first time, solid evidence for
Granovetter's hypothesis on the role of weak ties. Prof. Kertész will
show that the links of medium strength are the main carriers of new
information. The findings of the team have strong implications for
modeling society. If time permits, some further studies on social
interactions will also be mentioned.
