We performed corpus correction on a modality corpus for machine translation
by using such machine-learning methods as the maximum-entropy method. We thus
constructed a high-quality modality corpus based on corpus correction. We
compared several ki...

We have developed systems of two types for NTCIR2. One is an enhenced version
of the system we developed for NTCIR1 and IREX. It submitted retrieval results
for JJ and CC tasks. A variety of parameters were tried with the system. It
used such char...

It is often useful to sort words into an order that reflects relations among
their meanings as obtained by using a thesaurus. In this paper, we introduce a
method of arranging words semantically by using several types of `{\sf is-a}'
thesauri and ...

Robertson's 2-poisson information retrieve model does not use location and
category information. We constructed a framework using location and category
information in a 2-poisson model. We submitted two systems based on this
framework to the IREX ...

ACL Workshop, the Data-Driven Machine Translation, 2001      Dec 2001
This paper describes experiments carried out using a variety of
machine-learning methods, including the k-nearest neighborhood method that was
used in a previous study, for the translation of tense, aspect, and modality.
It was found that the supp...
