项目摘要

The object of this international joint research is for the researchers from Japan as well as Germany and the United States of America to analyze logically 'rule based reasoning', which belongs to the continental statutory law culture and 'case based reasoning' which belongs to the Anglo-American case law culture, clarify the mechanism of the interpretation of legal rules and legal analogy and amalgamate a rule based legal reasoning system with a case based legal reasoning system. In this international joint research the following results have been achieved :(1)Logical structures of 'rule based reasoning' in the continental law and 'case based reasoning' in the Anglo-American law have been in many points clarified.(2)The relationship between rule based reasoning and case based reasoning in law and the way to combine the both have been also clarified.(3)The methods of the representation of legal knowledge in terms of the logical flow chart and the compound predicate formula (CPF) has bee … More n developed.(4)The logical structure of the second part of United Nations Convention on Contracts for the International Sale of Goods (CISG) has been clarified. The part was represented in the computer in terms of the logical flow chart in English as well as in Japanese and also in terms of CPF partly. These knowledge representation methods have been adapted as a common representation form between the Japanese researchers and the American researchers.(5)Japanese researchers and American researchers discussed interpretation problems of several articles of CISG on the basis of logical flow charts of CISG, so that it was proved that this representation form is a fruitful method for Japanese and American lawyers, who have the different language and culture, to communicate with each other.(6)The several interesting issues of interpretation problems of CISG have been found. The relationship between these different interpretations and the different cultures of law became clear.(7)A Hyper Card system of CISG in German, English and French has been developed by the German researchers.On the following points the final object of the joint research to make a integrated system has been achieved only in the very restricted range :(1)A rule base legal reasoning system as well as a experimental system of legal analogy was developed. However we could not install any amalgamating system of rule based reasoning and case based reasoning in law.(2)Some experimental generating system of Japanese legal text and English Legal text from CPF was developed. However we could not develop any interface between Japanese and English language in law. Less

这项国际联合研究的对象是日本、德国和美国的研究人员对属于大陆成文法文化的“基于规则的推理”和属于欧洲大陆成文法文化的“基于案例的推理”进行逻辑分析。英美判例文化，明确法律规则的解释机制和法律类比，将基于规则的法律推理体系与基于案例的法律推理体系相结合，本次国际联合研究取得了以下成果：（1）。 “基于规则的推理”的逻辑结构大陆法与英美法中的“基于案例的推理”在很多方面都得到了澄清。(2)法律中基于规则的推理与基于案例的推理之间的关系以及两者结合的方式也得到了澄清。(3) )用逻辑流程图和复合谓词公式(CPF)来表示法律知识的方法已经发展起来。(4)《联合国国际合同公约》第二部分的逻辑结构货物销售 (CISG) 已该部分在计算机中以英语和日语的逻辑流程图以及部分CPF的形式表示，这些知识表示方法已被改编为日本研究人员和日本研究人员之间的通用表示形式。 (5)日本研究者和美国研究者在CISG逻辑流程图的基础上讨论了CISG几条条款的解释问题，从而证明这种表示形式对于日本和美国律师来说是一种卓有成效的方法。不同的语言和文化，相互交流(6)发现了CISG解释中几个有趣的问题，这些不同的解释与不同法律文化之间的关系变得清晰。(7)德语、英语和法语的CISG超级卡系统已经建立。联合研究的最终目标是在非常有限的范围内实现了一个综合系统：（1）基于规则的法律推理系统以及法律类比的实验系统但是我们无法安装任何合并系统。 (2)开发了一些基于CPF的日语法律文本和英语法律文本的实验性生成系统，但是我们无法在法律中开发任何日语和英语语言之间的接口。
