version process reinforced with a neural net-
work handler. The network is used by the
neural network handler and word associations
are done in parallel with kana-kanji conver-

To avoid these problems without increasing
computational costs, we propose the use of the
associative functionality of neural networks.
The use of association is a natural extension t...
