摘要
本文简要介绍中国科学院过程工程所(原化工冶金所)在Internet化学化工信息资源系统挖掘方面正在形成的一个较完整的化学专业信息获取平台,包括:(1)国家科学数字图书馆化学学科信息门户ChIN;(2)网络化学化工专业搜索引擎ChemEngine;(3)化学深层网挖掘工具ChemDB Portal。其中ChIN已经成熟,是国内权威、中国唯一被国际承认的网络化学资源导航系统;ChemEngine是通用搜索引擎技术与化学相关的领域知识相结合形成的化学化工专业搜索引擎,初步测试优于国际具有类似功能的系统:德国的ChemGuide和美国的ChemIndustry。ChemDB Portal则是正在进行的、基于XML对化学深层网数据进行提取和索引方法的研究,这一方法尚未见报道。这些工具可为检索网络化学相关信息提供更方便、更好的专业化解决方案。
This paper will briefly introduce a set of discovery and searching tools for Intemet chemical information established by Institute of Process Engineering, Chinese Academy of Sciences. Firstly, ChIN is a comprehensive web guide of Intemet chemistry resources created in 1997 and is running as the Chemistry Portal of the Chinese National Science Digital Library （ CSDL）, which is a international recognized and authoritative chemistry Web guide in China. Secondly, ChemEngine is a chemistry search engine that combines the t technique of general search engine for web information and the chemistry domain knowledge and comes out with beret performance when compared with the two similar services available, the FIZ Chieme＇s ChemGuide and CbemIndustry. corn based on preliminary test. Finally, ChemDB Portal is a new approach currently going for chemistry Deep Web data indexing and searching based on XML technology which has not yet been reported. These tools should provide better solutions for searching web chemical information for the professionals in chemical community.
