【摘要】 运用复杂网络理论,基于北京大学语言研究所做出的《人民日报》和国家语委现代汉语的语料库,构建了四个汉语词同现网络;并计算了测度指标。由结果绘制出分布曲线,证实了该词同现网络具有小世界效应和无标度特性。对上述词同现网络进行抗毁性分析,用最大连通子图尺寸下降率和整体效能下降率作为衡量复杂网络抗毁性的指标。实验结果表明对于词同现网中度和介数很大的节点的挖除,会使整个网络破裂为若干孤立的网,将使文章变的支离破碎。从侧面反映了汉语词中的核心词汇,对接下来为研究汉语词中的核心词汇提供了方案。更多还原

【Abstract】 Using complex network theory,the four Chinese word co-occurrence networks are constructed based on the corpora of the People’s Daily made by Peking University Institute of Languages and modern Chinese of The National Language Committee. The indices are calculated and the distribution curves are plotted by the results. It is proved that the word co-occurrence networks followed with small-world effect and scale-free property. For the above word co-occurrence networks,the analysis of invulnerabilitis carry out. The indices to measure the invulnerability of complex network are the decline rate of maximum connected subgraph size and overall efficiency. The experiment results show that the entire network rupture into several isolated network with the node of great degree and betweenness in the word co-occurrence networks removed. The article will become fragmented. It reflects laterally the core vocabulary in the Chinese words. Next,it provides a solution to study on the core vocabulary in Chinese words.更多还原
