Method for node mapping, network visualizing and screening

A network visualization method comprising the steps of:

• extracting, from a table which includes as elements node types, the number of connecting nodes to be connected to the nodes, and the number of end nodes to be connected to the nodes, connecting nodes which are connected to a predetermined number of, or more, end nodes;
• arranging the extracted connecting nodes onto a visualization space at a distance from each other, the distance being not less than a predetermined distance in accordance with the number of connecting nodes existing therebetween;
• arranging the remaining connecting nodes onto the visualization space;
• computing arrangement of the end nodes in the visualization space;
• adjusting the distance between the connecting nodes so that the end nodes do not overlap;
• and
• screen-visualizing line segments which represent the connections between mutually connected nodes.

A method for screening a regulatory substance, comprising the steps of:

• extracting, from a table which includes as elements node types, the number of connecting nodes to be connected to the nodes, and the number of end nodes to be connected to the nodes, connecting nodes which are connected to a predetermined number of, or more, end nodes;
• arranging the extracted connecting nodes onto a visualization space at a distance from each other, the distance being not less than a predetermined distance in accordance with the number of connecting nodes existing therebetween;
• arranging the remaining connecting nodes onto the visualization space;
• computing arrangement of the end nodes in the visualization space;
• adjusting the distance between the connecting nodes so that the end nodes do not overlap;
• screen-visualizing line segments which represent the connections between mutually connected nodes;
• and
• screening the regulatory substance which regulates an interaction between the nodes on the basis of the screen-visualized information.
