On the Implementation of an Internet-based Retrieval system in Oriental Historical Documents and the processing of Non-Standard Characters

通过分析东方学史料的文档结构，构建两个或两个以上相关史料的交叉引用(集成)检索系统，以促进历史研究的发展。基于Web上的CGI(Common Gateway Interface)功能，设计开发了东方学史料检索系统。首先，为了提高检索效率和多种高效的检索手段，我们用标准通用标记语言SGML(Standard Generalized Markup Language)对外国船只访问琉球王国的旧文献进行了检索。更详细地说，我们通过网络以标准通用标记语言(SGML)访问历史文档，将它们存储在数据库管理系统(Open Text)中，并使使用高速搜索引擎PAT50的应用程序和PIPE程序能够高速检索-这是为了创建一个有效的交叉引用系统，不仅通过文档编号检索信息，还通过发送者、接收者、日期、注释和内容检索信息。开发了基于汉字属性数据库的汉字检索功能、汉字显示功能和汉字转发功能。此外，我们还设计和构建了一个英日全文协同检索系统，该系统以日文、英文翻译和原始文档的图像页面的形式存储日本经典文献(小枝和日本本)以及琉球相关资料，并在网页(http://www.okinawa.oiu.ac.jp).)上向公众开放

The aim of this research was to promote history study such as to provide a new interpretation or analysis of historical materials by analyzing the document structures of the Orient study historical materials, and by constructing a cross-referential (integrated) retrieval system of two or more related the materials.The Orient study historical material retrieval system was designed and developed on the basis of the CGI (Common Gateway Interface) function on Web. First of all, to achieve an improvement of the retrieval efficiency and various, efficient retrieval means, we made the old documents concerning the foreign country ship visits to Ryukyu kingdom accessible in SGML (Standard Generalized Markup Language). To be more in detail, we made historical documents accessible in Standard Generalized Markup Language (SGML) via the web, stored them in the database management system (Open Text), and made it possible to retrieve at high speed by the application program that uses a high-speed search engine, PAT50, and the pipe programs_ This is to create an effective, cross-referential system to retrieve information not only via a document number but also via sender, receiver, date, annotation, and content. We also developed the Gaiji characters retrieval function, the Gaiji characters display function and the Gaiji characters forwarding function based on the Gaiji characters attribute database. Moreover, we designed and constructed an English-Japanese full text coordinated retrieval system, by storing Japanese classic documents (Kojiki and Nihonshoki), as well as Ryukyu-related materials, in the form of Japanese, English translations, image pages of original documents, and by adding simplified tags to them.These systems are open to the public on web page (http://www.okinawa.oiu.ac.jp).
