Nation Achievement of Science and Technology Database (CNKI Version) collected more than 560,000 achievements from 1978 till now. It mainly provided ifve kinds of function: Navigation function, search function, knowledge network node function, evaluating function and user management function. Knowledge Network Node is a special search-result display page created by CNKI. It is similar to citation links but much more powerful. hTe purpose is to improve research efficiency and make all closely related articles in contents available on a single page. Compared with usual achievement databases, every node of achievement in Nation Achievement of Science and Technology Database (CNKI Version) collects its bibliographic information and related journal articles, doctoral dissertations, masters' theses, proceedings papers, newspaper articles, standards, patents and so on,which ifnally formed the knowledge hierarchy of the achievement. In addition, this paper explored the new mode of database value-added services based on semantic navigation.%中国科技项目创新成果鉴定意见数据库（知网版）收录了1978年以来所有正式登记的中国科技成果数据，共计56万余项，集成了科技成果著述信息、知网学术文献总库中的期刊文章、硕博论文、会议论文、标准规范和专利文献等在内的各类资源，最终形成科技成果知识网络，并提供了导航功能、检索功能、知网节功能、评价功能和用户管理等各项服务。其中，知网节功能是对检索结果进行挖掘分析的资源整合模式，将所有具有密切联系的知识集成在一个汇编页面上。此外，文章基于语义分类导航理念，探索了数据库增值服务的新模式。
