Development of Japanese textbooks for Science and Technology

本项目研究开发如下：(1)需求分析;我们调查了理工科学生和他们的导师，了解他们必须如何学习专业课程，以及他们对自己的日语能力的感受。根据这项调查。我们注意到，来自非汉字地区的外国学生由于日语能力不足，在学习上存在更严重的问题。(2)为了给学生提供好的教材，我们尝试为理工科学生编写新的实用教材。本文收集了16本本科科学领域教科书，并将其制作成数据库，从以下几个层面进行分析。(a)汉字分析；(b)词形分析；利用词法自动分析系统，提取了近50万个语素，并按语法词类进行了分析。(c)句法分析;为特殊目的挑选重要的粒子等效词和短语(d)语篇分析；我们尝试开发语篇结构分析的算法。为此，我们编制了关键词矩阵程序，并用数据库对其进行了检验。我们也试着构建话语结构框架。这种方法将导致自动生成语篇分析算法。(4)编辑课本：(a)《技术日语阅读导论》。即语体、等价小品、指示词、名词短语、复句。(b)专家编写的简易日文科学技术教材（b1）测量血压（控制工程）（b2）石油与环境问题（化学）（b3）计算机体系结构

This project studied and developed as the followings. (1)Needs Analysis; We surveyed students of science and technology and their supervisors to know how they must study specialized subjects and how they feel about their Japanese languageability. According to this survey. we noticed that foreign students from non-kanji areas have more serious problems in studying because of lach of Japanese language ability.(2)In order to supply good textbooks for the students, we tried to made new practical textbooks for scientific and technical students. 16 textbooks for undergraduate students on scientific domains are collected and made as a database, which are analyzed from various levels such as the following.(a) analysis of kanji; frequency of Chinese characters (b)molphorogical analysis; using automatic morphology analysis system we got about 500,000 morphems, and examined them by the grammatical parts of speech.(c)syntactic analysis; picking important particle equivalent words and phrases for special purpose(d)discourse analysis; we tried to develop algolythms of discourse structure analysis. For this purpose we made keywords matrix program and examine it using database. And also we tried to make discourse structur frames. This approach will lead to automatic generation of discourse analysis algorithms.(4)Editing text boos : (a) Introduction to Reading Technical Japanese. i.e. style, particle equivalents, demonstratives, noun phrase, complex sentence.(b)The Science and Technical textbook in easy Japanese by specialists (b1) Measuring blood pressure(control engineering) (b2)petrolium and environmental problems (chemistry) (b3)computer architecture
