Systems and methods for determining whether a first document is a potential duplicate of a second document such that the two documents describe the same or substantially the same subject matter, wherein the first and second documents include attribute data in attribute fields. A set of rules is obtained for determining whether the first document is a potential duplicate of the second document. Moreover, for each rule in the set of rules, a determination is made as to whether data in a first set of attributes of the first document is contained in a second set of attributes of the second document. According to the results of the evaluated rules in the rules set, determining whether the first document is a potential duplicate of the second document. If, according to the evaluated rules in the rules set, the first document is determined to be a potential duplicate of the second document, storing a reference to the first document in a set of potential duplicates of the second document.
