Building a Japanese Parsed Corpus

该项目的目标是建立一个日语句法分析语料库，同时改进词法分析器和句法分析器。在两年的时间里，我们取得了以下成果：(A)我们增强了词法分析器Juman，能够对整个词串进行处理，并发现并输入正常词法分析不正确的有问题的固定短语。我们于1996年10月发布了增强版的Juman，JUMAN3.0。(B)我们在我们的句法分析器KNP中增强了对并列结构和从属结构的处理。KNP也得到了增强，可以处理几种具有特殊句法功能的短语。我们在1997年3月发布了KNP的增强版本KNP2.0。(C)我们制作了一个基于鼠标的界面，以帮助和加快对Juman和KNP分配的标记的人工更正。该界面还提供了语料库的检索功能。(D)截至1997年3月，我们已经构建了大约20,000个经过句法分析和手动更正的语料库。其中，我们在1997年3月开放了大约10,000个句子。

The goal of the project was to construct a Japnese parsed corpus and to simultaneously improve a morphological analyzer and a parser. In the period of two years' project, we have achieved the following results :(a) We enhanced our morphological analyzer JUMAN to handle a word string as a whole, and to find and enter problematic fixed expressions which were analyzed incorrectly by the normal morphological analysis. We released the enhanced version of JUMAN,JUMAN3.0 in October 1996.(b) We enhanced the treatment of coordination structures and subordinate structures in our parser, KNP.KNP was also enhanced to handle several types of phrases with exceptional sentential functions. We released the enhanced version of KNP,KNP2.0 In March 1997.(c) We made a mouse-based interface to help and to speed up the human correction of tags assigned by JUMAN and KNP.The interface also provides the retrieval functions for the corpus.(d) As of March 1997, we have constructed about 20,000 sentences of parsed and manually-corrected corpus. Out of them, we opened about 10,000 sentences in March 1997.
