【摘要】：當(dāng)前微博迅速流行,由于它交互結(jié)構(gòu)的復(fù)雜性,其研究分析難度較大,該文提出了一種新穎的方法分析微博信息傳播網(wǎng)絡(luò)的屬性。首先定義了信息源的概念,針對6個(gè)不同主題事件的微博傳播結(jié)構(gòu),對各信息傳播網(wǎng)絡(luò)結(jié)構(gòu)進(jìn)行了可視化分析,并給出了信息源分布特征分析。帶有時(shí)間標(biāo)簽的信息傳播網(wǎng)絡(luò)通常是有向非循環(huán)圖,定義了3種信息傳播微元結(jié)構(gòu),分別對應(yīng)信息分散、信息聚集、信息傳遞。利用斯皮爾曼等級相關(guān)系數(shù)研究了它們之間的關(guān)聯(lián)度,發(fā)現(xiàn)3種結(jié)構(gòu)間有相當(dāng)大的差異,基于這3種關(guān)系分析了信息傳播網(wǎng)絡(luò)的演變情況,得出信息分散結(jié)構(gòu)在各時(shí)間片上的數(shù)量最多。
[Abstract]:Because of the complexity of interaction structure, the research and analysis of Weibo is very difficult. In this paper, a novel method to analyze the properties of Weibo information transmission network is proposed. Firstly, the concept of information source is defined, and the information transmission network structure is visually analyzed for the Weibo propagation structure of six different topic events, and the distribution characteristics of information source are analyzed. The information transmission network with time label is usually directed aperiodic graph. Three kinds of information propagation microelement structures are defined, which correspond to information dispersion, information aggregation and information transmission respectively. The correlation degree between them is studied by using Spelman rank correlation coefficient. It is found that there are considerable differences among the three kinds of structures. Based on these three relationships, the evolution of information dissemination network is analyzed. It is concluded that the number of information dispersive structures in each time slice is the highest.
