As the new work mode develops, virtual collaborative environments play an increasingly important role in future business and personal activities. Our research proposes a new method of constructing collaborators social network model which considers both communication relations and cooperative relations between cooperators. This method uses public information on the work platform to discover the cooperator’s behaviors, discovers community relationship intensity between collaborators and uses these to construct the coordinators social network model. Finally, we use the test data from the open source community website
to prove the validity of the model and the method. As a result, this method does not only improve the connectivity of social networks, but also reflects each collaborator’s role of team better.
