Abstract
Abstract In method of displaying items of information organized in a hierarchical structure, a hierarchical tree of nodes is displayed, which are items of information, classified based on a specified concept. The user selects an intended node from among the nodes on the displayed hierarchical tree and enters a concept for classifying nodes of sub-concepts of the selected nodes. The selected node and a partial hierarchical tree that is created based on the entered; concept are displayed.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
186 words
A method of displaying a hierarchical tree of nodes, each node of which comprises an item of information representing a concept defining a noun, a name of numerical value or a unit, wherein at least two of said concepts have an is-a relation as a hierarchical relationship therebetween, a generic relation comprising a general relation as a non-hierarchical relationship therebetween or an instance relation that comprises an exemplified relation of a corresponding generic relation, said method comprising the steps of: displaying a hierarchical tree of nodes indicative of is-a relations among the concepts; selecting a first node from the hierarchical tree of nodes; displaying, in response to the first node, the selected first node and a partial hierarchical tree of nodes lower than the selected first node; displaying an attribute representing the generic relation corresponding to the instance relation which exists among the nodes of the partial hierarchical tree; selecting an attribute from among the displayed attributes; classifying the partial hierarchical tree of nodes according to the selected attribute so as to extract nodes associated with the selected attribute; and displaying the classified partial hierarchical tree.
Claim 2
Independent Claim

A method of displaying a hierarchical tree of nodes, each node of which comprises an item of information representing a concept defining a noun, a name of numerical value or a unit, wherein at least two of said concepts have an is-a relation as a hierarchical relationship therebetween, a generic relation comprising a general relation as a non-hierarchical relationship therebetween or an instance relation that comprises an exemplified relation of a corresponding generic relation, said method comprising the steps of: displaying a hierarchical tree of nodes indicative of is-a relations among the concepts; selecting a first node from the hierarchical tree of nodes; displaying, in response to the first node, the selected first node and a partial hierarchical tree of nodes lower than the selected first node; displaying an attribute representing the generic relation corresponding to the instance relation which exists among the nodes of the partial hierarchical tree; selecting an attribute from among the displayed attributes; classifying the partial hierarchical tree of nodes according to the selected attribute so as to extract nodes associated with the selected attribute; and displaying the classified partial hierarchical tree.
Claim 3
Dependent Claim
61 words
The hierarchical structure display method according to claim 1, further including the steps of: displaying nodes associated with the selected attribute; inputting a second node selected by a user from among the nodes associated with the selected attribute; classifying the partial hierarchical tree of nodes according to the selected attribute and the second node; and displaying the classified partial hierarchical tree.
Claim 4
Dependent Claim
71 words
The hierarchical structure display method according to claim 1, further including the steps of: displaying nodes and their lower nodes as a second partial hierarchical tree associated with the selected attribute; inputting a second node selected by a user from among the nodes of the second partial hierarchical tree; classifying the second partial hierarchical tree of nodes according to the selected second node; and displaying the classified second partial hierarchical tree.
Claim 5
Dependent Claim
67 words
The hierarchical structure display method according to claim 1, further including the steps of: displaying nodes as a second partial hierarchical tree associated with the selected attribute; inputting a second node selected by a user from among the nodes of the second partial hierarchical tree; classifying the second partial hierarchical tree of nodes according to the selected second node; and displaying the classified second partial hierarchical tree.
Claim 6
Dependent Claim
23 words
The hierarchical structure display method according to claim 1, further including the step of displaying nodes associated with the classified partial hierarchical tree.
Claim 7
Dependent Claim
34 words
The hierarchical structure display method according to claim 1, further including the steps of: replacing the first node with a lower node from the first node; and, displaying attributes according to the lower node.
Claim 8
Dependent Claim
25 words
The hierarchical structure display method according to claim 1, further including the step of displaying the classified partial hierarchical tree together with the first node.
