Observations about 232 members of the Eclipse Marketplace and 16 suppliers' solutions are used to: (i) define a model to measure trust; (ii) implement an automated approach to calculate trust opinion values of suppliers' solutions offered in the marketplace; and (iii) produce insights on ways to increase belief and decrease customer's uncertainty about suppliers' solutions. Results suggest that trust values decrease customer uncertainty about a supplier's solution but do not increase customer belief in the solution.
