Extraction of important numerical pairs from text documents and visualization of them.

2. Our system’s overview This system first extracts two units and one item expression from documents, it then extracts numerical pairs from sentences including the two units and the item expression; finally, it arranges the pairs and displays them in graphs. (Ex.) When documents on typhoon are given, the system extracts “hectopascal” and “m/s” as units and “maximum wind speed” as an item expression. It next extracts values related to “hectopascal” and “m/s”. Finally, it produces a graph where the value related to “hectopascal” is used for the horizontal axis, and the value related to “m/s” is used for the vertical axis.
