摘要：This study aims at characterizing the collaboration ties between the centres of the Distributed Computing ALICE infrastructure based on social networks methods. A selfadministered questionnaire was sent to all center managers about support, email interactions, conflict and future collaborations in the infrastructure. Answers for 50 centers were received and considered in the empirical analysis (68% response rate). Empirical analysis shows that the network is centralized on CERN. There are however a series of centers which form cohesive subgroups, and a willingness to promote more interactions at the regional level. Interestingly, social relationships are only loosely correlated with computer exchanges.
