ABSTRACT:
The invention provides a method and system to compare data objects. Each data object is converted into a directed acyclic graph forest, which comprises one or more directed acyclic graphs. The directed acyclic graph forests corresponding to data objects are then compared to calculate a similarity score between the data objects. The similarity score is then used as a measure to determine the extent of similarity between the data objects.
