【摘要】：化学家利用Internet通用资源搜索引擎如Yahoo、Google获取Internet资源时,检索结果常包含大量相关性较小的内容。Internet化学资源导航系统如ChemDex用人工方法收集和组织资源使资源内容质量和相关性比通用搜索引擎有所提高,但进行细致的分类仍比较困难。由中国科学院过程工程研究所建立、Internet化学化工资源导航系统ChIN的维护工具ChIN-Manag-er采用把两个内容相关的资源简介页互链来表示资源之间的密切相关关系,目前维护人员主要通用测览分类目录来确定相关资源,但这种方式在被索引的资源数量日益增大时其可用性降低。本论文开发了一种新的基于ChIN数据库检索的链接两个关系密切的相关简介页的方法。该方法针对ChIN数据库中简介页的组织特点设计了面向不同资源类型数据表的多种检索策略,这些策略侧重于被检索字段的确定;并为20余种不同类型的资源描述表建立了实现相应检索策略的检索界面。这些检索界面无缝集成到了ChIN-Manager相应的资源编辑界面中,为ChIN提供了一种快速确定被索引资源的密切相关资源的方法。
[Abstract]:Such as Yahoo search engine using Internet universal resource chemist, Google access Internet resources, search results often contain a large number of relatively small content of.Internet chemical resource navigation systems such as ChemDex resources quality and relevance than the general search engine is improved by artificial methods and organizational resources, but the detailed classification established by still more difficult. Process engineering research China academy, Internet chemical resources navigator ChIN system maintenance tool ChIN-Manag-er two content related to the resources of one introduction page to represent the relationship between resources are closely related, the maintenance staff of major general browse catalogs to determine the related resources, but in this way the number is increasing when the index of resources the reduced availability. This paper developed a new algorithm based on ChIN database link two The method is closely related to the relevant introduction page. The method for tissue features in the ChIN database page is designed for a variety of different types of resource data table retrieval strategies, these strategies are focused on the search field to determine; and more than 20 different types of resource description table is established to achieve the corresponding search strategy search interface. The retrieval interface seamlessly into the corresponding ChIN-Manager resource editor interface, provides a rapid method to determine the resources is closely related to the resource index is ChIN.
