1. A method for determining associations between data objects, the method comprising: for a group of data objects including a first data object, a second data object, and a third data object, executing a matching algorithm to determine one or more duplicate data object propositions among the data objects, a duplicate data object proposition between two objects indicating a possibility that the two objects are duplicates of each other; detecting a duplicate data object proposition between the first data object and the second data object; identifying the first data object as a potential duplicate of the second data object based on the duplicate data object proposition between the first data object and the second data object; and in response to the identifying of the first data object as a potential duplicate of the second data object, determining whether the first data object identified as a potential duplicate of the second data object is an actual duplicate of the second data object by examining one or more duplicate data object propositions including at least a duplicate data object proposition between the third data object and the first data object.
