Abstract: A method, system, computer program product, server, and interface for managing query results includes receiving query results and semantic structuring information, and defining a root node corresponding to the query to which the results relate. A semantically structured tree descending from a root node has intermediate nodes in layers according to the semantic structuring information. The leaf nodes each correspond to a query result. The leaf nodes are attached to the tree based on an uptree relation. The tree has a space cube structure balanced on the basis of a semantic threshold.

Abstract: Collected user parameters include category 210, category weight 230, and value 240 information. A search support application creates 300 a query based on the user parameters. The query is sent to structured 450 and unstructured 470 databases, and heterogeneous query results are stored 630. Stored query results are ordered in a tree-shaped hierarchy (FIG. 8). The tree-shaped hierarchy has ordered levels of nodes 710-750 with levels corresponding to categories, and nodes 1.0-3.9 corresponding to values for categories. Leaf nodes 4.0-4.15 correspond to actual results 900-915, but the intermediate nodes 1.0-4.15 correspond to conceptual or meta relationships. Display of the results is restricted using the tree-shaped hierarchy to help manage result complexity.
