Non-hierarchical relationship UIs ("topology UIs") are difficult to scale to hundreds or more items. An embodiment of this invention provides indicators and quick access controls for the nodes in navigation tree that appear more than once in a hierarchy--where a pure hierarchical navigational tree falls short. The navigational tree is structured by grouping all matching nodes together. The display area displays the most frequent and the concatenated labels of the semantically grouped redundant nodes. A set of contextual proximity and similarity information and an exception list are stored in a semantic database which is configurable by system administrators. These navigation area controls and indicators will preemptively handle non-hierarchies directly within the navigation tree.
