摘要
传统的知识组织系统评价方式存在缺乏宏观测度,时滞过长,不能动态揭示等缺陷。本文结合复杂网络理论,从基本特性、动态特性和鲁棒性三个角度着手,对汉语科技词系统网络特性进行分析。基本特性的分析表明,汉语科技词系统同时具有小世界特性和无尺度特性,连通性良好,但是存在错误建设和重复建设的问题;动态特性的分析则表明,汉语科技词系统的小世界特性越来越显著,同时网络的性能有待进一步提高;鲁棒性的分析表明,汉语科技词系统网络面对随机删除时,具有良好的鲁棒性,面对蓄意攻击时,表现出较强的脆弱性。建议在以后的建设过程中采用有导向的建设,在系统管理和维护的过程中要注重词汇间相互关系,保证系统的连通性。
The evaluation of the traditional knowledge organization systems lacks of macroeconomic measure,works out very late,and cann＇t reveal dynamic process.Based on complex network theory,this paper has analyzed the network properties of the Chinese science and technology vocabulary system from the aspects of basic characteristics,dynamic characteristics and robustness.The analysis of basic characteristics shows that the Chinese science and technology vocabulary system is a small-world and scale-free network,and it has good connexity.But there are errors and multiplicity; The analysis of dynamic property shows that the system is much more small-world,while the networks performance should be further improved.The analysis of robustness shows that the systerm is much robust.So that the suggestion has been advanced that the vocabulary system should be constructed under the direction,and the importance should be attached to each and every vocabulary to ensure the connectivity of the system.
