| 中文摘要 | 随着Internet的快速发展，它已成为一种获取信息的新媒体。为了引导Internet用户到达他需要的资源，人们通过Internet通用资源搜索引擎和专业化的资源导航系统来对资源进行定位。ChIN(the Chemical Information Network)网站是在联合国教科文组织UNESCO（United Nations Educational, Scientific and Cultural Organization）和国家自然科学基金委员会支持下建立的化学和化工领域方面的一个专业化资源导航系统。在本论文中对已经运行了3年的ChIN网站进行了分析。研究了由于采用文件目录来管理和存储信息的方式和维护的效率，对 ChIN进行了重新设计和实施，采用基于数据库的方法对ChIN的数据有效地进行管理；编制了ChIN站点的管理工具：“ChIN-Manager (ChIN管理系统)。”通过ChIN-Manager可以减少ChIN的数据整理和存储、分类和维护分类结构等工作量，将数据发布的工作自动完成，从而可以使编辑人员集中精力处理数据的内容和相互之间的关系。本论文介绍了ChIN-Manager的设计和实施。根据对ChIN的数据内容的分析提取出若干种数据模式，并根据这些模式设计数据库表。在论文中针对一些具体问题以及解决办法进行了介绍。针对第一版ChIN中分类维护困难的问题，在第二版ChIN中采用先建立分类参考模型然后建立ChIN分类结构的做法，通过ChIN-Manager方便了分类结构维护，解决了目录页中的资源合理分组的排序的问题。本论文还介绍了简介页中的一些改进。通过以上方面的改进，方便了第二版ChIN的维护与管理，为ChIN向Internet用户提供更好的资源导航提供了保障。 |
| 英文摘要 | With the rapid growth of Internet, it is becoming a new media for scientific information. Search engine and subject oriented navigator are the two essential tools for users to access information on Internet. ChIN(the Chemical Information Network) is an Internet chemical resources navigator to help chemists to find chemistry information on Internet, which was developed under the joint support UNESCO(United Nations Educational, Scientific and Cultural Organization) and NNSFC(the National Natural Science Foundation of China). The current version of ChIN pages mainly consists of HTML documents. ChIN's maintenance relies heavily on the HTML editor at present, which has become more and more difficult for editors to keep it up to data as the size of ChIN grows larger. To improve the maintaining efficiency and performance of ChIN, a database based software "ChIN-Manager" has been created. ChIN-Manager is a program that ChIN editors can use to edit, categorize and store the resource information they collect from Internet, and it can generate the HTML files (including list pages and summary pages) and upload the files to the Web server. With the help of ChIN-Manager, it is easy and efficient for the editors to accomplish their daily work, including data editing, categorizing, and automated publishing, so the editors can concentrate on the content of the data and the relevancy among the resources. The design and construction of ChIN-Manager will be introduced. Tables of ChIN's database are created based on the analysis on ChIN's data. To overcome the difficulty of maintaining the category structure of ChIN, some reference category models were setup, and the category structure of ChIN was setup according to the referenced models. The summary page links in the list pages are first grouped and then sorted, according to the weights that the summary pages have. Improvements of the summary pages in the new edition of ChIN are also introduced in this paper. With the improvements above, ChIN is more efficient to maintain, and will provide better performance. |
