Abstract: An online social networking system receives a first set of data associated with activities between its members and its competitors. The system uses the first set of data to develop and train propensity models to predict when the members and the competitors are likely to establish a business relationship. The system tests the propensity models to determine a best propensity model and selects that best propensity model. The system receives a second set of data associated with activities between a particular member and particular competitor. The system uses the best propensity model for predicting when the particular member and the particular competitor are likely to establish a business relationship based on the second set of data, and transmits an electronic message to the particular member relating to the business relationship between the particular member and the particular competitor.
