Development of Kanji Dectinoary for foreigners in Japanese Language Education

本文介绍了为外国人学习日语而开发的电子汉字词典“Kanjirin”和电子汉字成语词典“KIDS”。关于汉字林，在汉字信息处理领域中提出了一些汉字数据库，但这些汉字数据库不能将汉字知识表示为表意文字。我们整理了1945年汉字（Joyo kanji）的1，011个部分结构。这些部件结构将属性继承给汉字。我们称这些部分结构为“基元”，并开发了汉字知识库，其中汉字是由基元表示，可以通过各种条件进行搜索。用户可以从知识库中得到汉字的意义和发音的解释。我们使用这个汉字知识库开发了汉字林。Kanjirin具有用户友好的界面。初学者可以撤消汉字搜索操作的crrections和搜索复杂的汉字从简单的汉字部分。关于KIDS，据说外国人了解他们应该学习的汉字成语的区域，并且他们试图学习与上述成语相关的其他成语。对于这类学习，我们认为词典的框架适合于汉字成语的自由学习。KIDS可以进行以下检索：汉字成语与其组成部分汉字之间关系的知识检索、汉字成语与汉字之间关系的知识检索以及利用汉字成语的语义、发音等属性进行的关系词检索。另外，KIDS的知识库是基于可扩展数据库的，学生可以对知识库进行自定义，我们在EWS NWS-1750（SONY）上开发了KIDS。KIDS有一个OSF/Motif界面，可以轻松地搜索汉字成语及其知识。此外，我们还利用汉字林和KIDS的知识库开发了两个汉字学习ICAI系统“汉字实验室”和“JUGAME”。

This paper describes development of an electronic kanji dictionary called"Kanjirin" and an electronic kanji idioms dictionary called KIDS, for foreigners to learn Japanese language. With regard to Kanjirin, some kanji data bases are proposed in the field of information processing on kanji but these kanji data bases can not represent kanji knowledge as ideograph. We have arranged 1,011 partial structures from 1945 kanji(Joyo kanji). These parts structures give inheritance of attributes to kanji. We call these part structures "primitives" and have developed kanji knowledge base wherein kanji is represented by primitives and can be searched by various conditions. Useres can get the explanation of meaning and pronunciation of kanji from the knowledge base. We have developed Kanjirin by using this kanji knowledge base. Kanjirin has user friendly interface. Novices can undo crrections of kanji search operations and search complicated kanji from easer kanji parts. With regard to KIDS, it is said that the foreigners understand the area of kanji idioms which they should be learned and they try to learn other idioms related with the above idioms. For this type of learning, we think the framework of dictionary is appropriate to learn kanji idioms freely. KIDS can perform the following searching : a knowledge search about the relation between kanji idiom and its component kanji, a knowledge search about the relation berween the two of kanji, and a relational-word search using the kanji idiom's attributes such as meaning and pronunciation. In addition, a knowledge base of KIDS is based on extensible database and the student can customize it. We have developed KIDS on EWS NWS-1750(SONY). KIDS has an OSF/Motif interface to search kanji idioms and their knowledge easily. In addition, we have developed two kanji learning ICAI system "Kanji Laboratory" and "JUGAME" by using the knowledge bases of Kanjirin and KIDS.
