"One of the most interesting scientific challenges nowadays deals with\r\nthe analysis and the understanding of complex networks' dynamics and how their\r\nprocesses lead to emergence according to the interactions among their components.\r\nIn this paper we approach the definition of new methodologies for the visualization\r\nand the exploration of the dynamics at play in real dynamic social networks.We\r\npresent a recently introduced formalism called TVG (for time-varying graphs), which\r\nwas initially developed to model and analyze highly-dynamic and infrastructure-less\r\ncommunication networks. As an application context, we chose the case of scientific\r\ncommunities by analyzing a portion of the ArXiv repository (ten years of publications\r\nin physics). The analysis presented in the paper passes through different data\r\ntransformations aimed at providing different perspectives on the scientific community\r\nand its evolutions.\r\nOn a first level we discuss the dataset by means of both a static and temporal\r\nanalysis of citations and co-authorships networks. Afterward, as we consider that\r\nscientific communities are at the same time communities of practice (through coauthorship)\r\nand that a citation represents a deliberative selection pointing out the\r\nrelevance of a work in its scientific domain, we introduce a new transformation aimed\r\nat capturing the interdependencies between collaborations' patterns and citations'\r\neffects and how they make evolve a goal oriented systems as Science.\r\nFinally, we show how through the TVG formalism and derived indicators, it is\r\npossible to capture the interactions patterns behind the emergence (selection) of\r\na sub-community among others, as a goal-driven preferential attachment toward a\r\nset of authors among which there are some key scientists (Nobel prizes) acting as\r\nattractors on the community."^^ .
