Various methods have been proposed for automatic synonym acquisition, as synonyms are one of the most fundamental lexical knowledge. Whereas many methods are based on contextual clues of words, little attention has been paid to what kind of categories of contextual information are useful for the purpose. This study has experimentally investigated the impact of contextual information selection, by extracting three kinds of word relationships from corpora: dependency, sentence co-occurrence, and proximity. The evaluation result shows that while dependency and proximity perform relatively well by themselves, combination of two or more kinds of contextual information gives more stable performance. We've further investigated useful selection of dependency relations and modification categories, and it is found that modification has the greatest contribution, even greater than the widely adopted subjectobject combination.

Recently, society has expressed increased demands for translation of Japanese statutes into foreign languages. The various motivations behind these demands include social and economic globalization and the need for technical assistance to legal reform. In this paper, we describe the problem of translating Japanese statues and show how to solve it by utilizing technologies developed for natural language processing. In particular, we show how to support both the compilation of a standard bilingual dictionary and the unification of translation equivalents of legal technical terms in compliance with the dictionary by using word alignment.

Automatic Consolidation of Japanese Statutes based on Formalization of Amendment Sentences 査読有り

Yasuhiro Ogawa, Shintaro Inagaki, Katsuhiko Toyama

Proc. 1st Int. Workshop on Juris-informatics 頁： 18-29 2007年6月

To realize computer-supported works in the areas of legislation and the practical use of laws, a statute database is indispensable so that users can easily retrieve desired versions of desired statutes. However, almost all former versions of statutes need to be restored since they cannot
be easily obtained or digitalized. This task can be achieved by repeatedly consolidating
amendment statutes with each version of the statute from the first one. In this paper, for Japanese statutes, we show that amendment clauses, which are parts of amendment sentences, can be formalized in terms of sixteen regular expressions.
We also propose an automatic consolidation system for Japanese statutes based on the formalization and experts' knowledge about consolidation. System evaluation is shown through a consolidation experiment.
