Development of Writing Tools for Japanese Documents on a Personal Computer

日本的文字处理器被设计成只用于文档的输入、编辑、错误和输出，而不积极地支持提高写作水平。我们为机器可读的日语文档开发了一个书写工具系统，称为SUIKOU，它可以对日语文档进行文本分析，并为撰写者提供有用的信息来完善写作。首先，我们在主机上开发了随口。在本研究中，我们将SUIKOU移植到个人电脑上，扩展其功能，改进其用户界面，并将其投入实际使用。SUIKOU运行在个人电脑NEC PC9801上，内存超过512KD。SUIKOU的程序是用c语言编写的，采用高速滚动和简单的多窗口，改进了用户界面。SUIKOU有两种命令：原语和宏。后一种命令是通过组合原始命令为主要用户准备的。当用户调用时，SUIKOU在屏幕上显示宏命令菜单。用户可以通过在菜单中选择功能来执行功能。每个宏命令在一秒钟内响应，分析包含10000个日文字符的文档并显示结果。我们设计了原始命令，分别对句子集和字符串集进行操作。基本命令分为五类：显示命令、提取命令、排序命令、设置命令和杂项命令。为了实现提取命令，我们设计了几种算法，在没有机器字典和语法分析的情况下对文档进行文本分析，并从中提取有用的信息。在实现这些算法时，我们使用了我们开发的适合日语文档的模式匹配技术。我们准备了一份在线手册，方便您在使用随口时参考。

Japanese word processors are so designed as only for input, editing, stror, and output of documents, but do not positively support to improve the writing. We have developed a system of writing tools for machine-readable Japanese documents, called SUIKOU, which analyzes a Japanese document textually and provides the writer with the useful information for polishing the writitg. At first we developed SUIKOU on mainframe. In this research, we transferred SUIKOU on a personal computer, extended its functions, improved its user interfaces, and put it to the practical use.1. SUIKOU runs on a personal computer NEC PC9801 with more than 512KD RAM. The program of SUIKOU is written in the language C. By adopting the high speed scrolling and simple multi-window, we improved the user interfaces.2. SUIKOU has two kinds of commands : primitives and macros. The latter commands which are prepared for primary users by combining the primitive commands. When invoked by a user, SUIKOU displays the macro command menu on a screen. The user can perform a function by selecting it among the menu. Each macro command responds within a second to analyze a document with 10000 Japanese characters and display the result.3. We designed primitive commands to operate on sets of sentences and sets of character strings, respectively. primitive commands are classified into five groups : displaying, extracting, sorting, setoperating, and miscellaneous command.4. To implement the extracting commands, we devised several algorithms which analyze a document textually without machine dictionaries nor grammatical analyses and extract the useful information from it. While implementing these algorithms, we used pattern matching techniques which we developed to be suitable for Japanese documents.5. We prepare an online manual which can be easily referenced while using SUIKOU.
