An approach for visualizing versions of a hierarchically organized object is provided. A visualization is generated to include first and second versions including information from multiple hierarchical levels of trees representing the versions. The visualization is generated so that the second version highlights a value of a dimension for a labeled path of the tree representing the second version. The highlighted value differs from a corresponding value of a dimension for a labeled path of the tree representing the first version based on a vector space constructed to have multiple dimensions for each labeled path of the trees. A similarity measure between the first and second versions is computed by normalizing a first vector associated with the first version, normalizing a second vector associated with the second version, and determining a product of the normalized first vector and the normalized second vector. |
