Research for WWW Information Service in Digital Archives of Japanese Literature

我们开发了WWW信息系统来搜索互联网上日本文学的数字档案，如翻译文本和象形文字图像数据，这些都是互联网上这一领域的研究材料。首先，为了识别是否存在数字档案，我们利用该领域的技术术语，如书名、人名和地名，分析了已知的拥有数字档案的网站的页面描述。然后，我们提取了典型的描述模式。在此基础上，我们开发了JLDA_Filter(日本文学数字档案馆过滤器)，这是一种特定领域的过滤器，用于提取足够的描述来判断这是一个数字档案馆。利用这个过滤器，我们开发和评估的WWW信息系统包括两个部分：第一部分是利用该领域的技术术语词典来缩小URL的范围；第二部分是使用JLDA_Filter来判断网站是否有预期的归档。一种是通过更多地分析描述，给出每个档案的来源和特征作为元数据，例如，哪些是原著和不同的版本，谁翻译的，谁是所有者等。二是利用我们的日文典籍位置信息数据库，实现了在互联网上同时检索原著和电子书的位置的功能。

We developed the WWW Information system to search the digital archives of Japanese Literature, such as translated text and hieroglyphic image data, which are research materials in this field on Internet.At the first to recognize if there is digital archives, we analyzed the page description of known sites which have such digital archives by using technical terms of this domain, such as book name, person name, and place name. Then we extracted the typical pattern of descriptions. Based on this analysis, we developed jlda_filter ( Japanese Literary Digital Archive_filter ) which is the domain specific filter to extract the description enough to judge that is the digital archiving site. By using this filter, we developed and evaluated WWW Information system consists of two parts; the first is to narrow down URL by using technical term dictionaries in this domain and the second is to judge if the site has expected archives by using jlda_filter.In the next, we have two plans. The one is to give origin and feature of each archive as metadata by analyzing descriptions more, for example, which is the original book and different editions, who translated, and who is the owner, etc... The other is to give the function to retrieve both locations of original book and its electric copy on Internet by using our Location Information DB of classical Japanese Literary books simultaneously.
