Claim One:
1. A method performed by one or more processors configured with computer-executable instructions, the method comprising: obtaining an initial classification structure tree, the initial classification structure tree including an initial root node and at least a first child node and a second child node, the first child node and the second child node including a same name, the second child node having a parent node that is at least one level higher than the second child node in the initial classification structure tree; generating a reorganized classification structure tree that at least uses the first child node or the second child node as a root node of a reorganized classification structure tree and the parent node of the second child node in the initial classification tree as a child node of the root node of the reorganized classification structure tree without including either the first child node or the second child node as the child node of the root node of the reorganized classification structure tree; and using the initial root node of the initial classification structure or the root node of the reorganized classification structure tree as guidance information of data source characteristics for display at a display interface.
