We collected a large number of Japanese-English parallel sentences
from many electronic media sources. Then we selected simple sentences
from these Japanese-English parallel sentences[Murakami
2007]. We
used these Japanese-English simple sentences for training and
development and test data.
Also we formed these sentences as follows. We used the English punctuation system, which means we changed ``,'' and ``.'' to `` '' and `` ''. And, we did not take into account English case forms. Also, we used Chasen [Asahara and Matsumoto2000] as the Japanese morphological analyzer.
