Techniques are disclosed for comparing data between dissimilar data hierarchies. Techniques provide an entity pool comprising multiple entities having established relationships and hierarchies. A user selects data from one hierarchy, and a mapping to a node in a structure that provides a normalized hierarchy is found. After identifying a node mapped to the data selection, elements corresponding to a second hierarchy that also maps to the same node (or otherwise obtained from using known natural language processing techniques) are identified. Doing so allows comparable elements of otherwise dissimilar hierarchies to be identified.
