Abstract: Systems and methods for establishing and studying networks of professionals and how they associate, learn, and behave are disclosed. In methods according to embodiments of the invention, networks of professionals are defined by administering sociometric surveys to a group of professionals, or by culling already available data about the professionals from other data sources. Behavioral data is also imported, and methods and systems according to embodiments of the invention allow behavioral data to be overlaid on network data. Metrics can be calculated indicating the importance of a particular professional based on his or her influence on the behavior of others in his or her network. This network data and other data can then be used to define business goals and objectives, segment a customer base according to user-defined characteristics, deliver targeted marketing interventions, and understand the effects of those interventions.
