Abstract:
1. A method for obtaining hierarchical information of planar data, the method comprising: mapping at least one data item from a same data set in the planar data to at least one node in a full tree structure formed by a structured terminology system; obtaining at least one sub tree structure in the full tree structure, each of the at least one sub tree structure taking the at least one node as leaf nodes of the sub tree structure; selecting a target tree structure from the at least one sub tree structure; obtaining hierarchical information in the target tree structure; determining a path length from a root node of the sub tree structure to a certain leaf node for each of the at least one sub tree structure; and selecting a sub tree structure with a path length shorter than at least one other determined path length as the target tree structure; wherein the step of obtaining at least one sub tree structure in the full tree structure comprises: wherein the step of obtaining at least one sub tree structure in the full tree structure further comprises:
