【摘要】：社會網(wǎng)絡中普遍存在著二元不對稱關(guān)系,在網(wǎng)絡動態(tài)演化過程中對二元不對稱關(guān)系預測是基于現(xiàn)有的大量網(wǎng)絡結(jié)構(gòu)信息,判定信息的有效性是提高預測效率和預測結(jié)果正確率的重要保證.文章針對二元不對稱關(guān)系預測提出了變量非獨立性假設(shè)以及檢驗算法,并通過建立正態(tài)性檢驗算法進一步提高非獨立性檢驗的效率.實例驗證表明本文所提出的方法是合理的.
[Abstract]:There are binary asymmetric relationships in social networks. In the process of network dynamic evolution, the prediction of binary asymmetric relationships is based on a large number of existing network information. The validity of decision information is an important guarantee to improve the prediction efficiency and the accuracy of prediction results. In this paper, the variable independence hypothesis and the test algorithm are proposed for the prediction of binary asymmetric relations. The efficiency of the non-independence test is further improved by establishing the normality test algorithm. The example shows that the method proposed in this paper is reasonable.
