Ego-clustering based propagation prediction of time series in social networks 基于自我聚类的社交网络时间序列传播预测
Fei Teng, Rong Tang, Tianrui Li
Online social networks are now recognized as an important platform for propagating information. Recently, a lot of efforts are made to predict the popularity of social information, to help the government and companies effectively control and guide public opinions. Information propagation in social networks exist many different temporal patterns, which are useful reference for predicting the future spreading of news. Considering temporal patterns are related to the network structure and information content, some researchers formulated a time series clustering problem to obtain tem­poral patterns in social networks. Previous clustering based algorithms take each cluster center as a typical propagation pattern, and then classify prediction object into its nearest-neighbor cluster. However, the nearest pattern can not fit the prediction object very precisely. This paper proposes a novel E-CTPM (Ego-Clustering based Temporal Prediction Model). E-CTPM utilizes the prediction object itself as a fixed cluster center, which can attract the most similar time series into one cluster and generate an ego-pattern for the prediction object. The tailored pattern fits the prediction object well, so it is suitable to indicate the future propagation. Experiments are carried on twitter and phrase datasets, with the results that E-CTPM outperforms the existing algorithms by achieving lower prediction bias and prediction variance. Meanwhile, E-CTPM has general applicability, which is able to work with multiple clustering methods and avoids the prediction difference resulting from classification methods.
在线社交网络现在被认为是传播信息的重要平台。最近,人们在预测社会信息的流行程度方面做了很多努力,以帮助政府和企业有效地控制和引导舆论。信息在社交网络中的传播存在着多种不同的时间模式,这为预测新闻未来的传播提供了有益的参考。考虑到时间模式与网络结构和信息内容有关,一些研究者提出了一个时间序列聚类问题来获取社会网络中的时间-时间模式。以往基于聚类的算法将每个聚类中心作为典型的传播模式,然后将预测对象分类到最近邻的聚类中。然而,最接近的模式不能非常精确地拟合预测对象。提出了一种基于自我聚类的时间预测模型。E-CTPM利用预测对象本身作为固定的聚类中心,将最相似的时间序列吸引到一个聚类中,生成预测对象的自我模式。该裁剪模式与预测对象拟合较好,适合用于预测未来的传播。在twitter和短语数据集上进行了实验,结果表明,E-CTPM在预测偏差和预测方差方面均优于现有算法。同时,E-CTPM具有通用性,能够与多种聚类方法协同工作,避免了因分类方法导致的预测差异。

An explanation of the sentencing of willful and malicious injury crime based on inference rules 基于推理规则的故意恶意伤害罪量刑解释
Caijuan Zhang, Ming Jiang
In the criminal law of all countries, the crime of willful and malicious injury is a common accusation. The offender must bear the criminal responsibility and be punished by criminal penalty. However, because of the complexity of the circumstances for adjudication, the various kinds of statutory sentence, and the wide extent of the fixed-term imprisonment, the sentencing imbalance can be caused, such as different responsibility for same crime and different punishments for same responsibilities. In this paper, the penalty for the crime of willful and malicious injury is the main object of study, and some rules of sentencing reasoning are put forward to restrict the discretion of judges and to improve the impartiality and enforce-ability of punishment.
在各国刑法中,故意恶意伤害罪是一种常见的罪名。违法者必须承担刑事责任,依法追究刑事责任。但是,由于判决情节的复杂性、法定量刑种类的多样性、有期徒刑的适用范围的广泛性,会造成量刑不平衡,出现同罪不同责、同责不同刑等现象。本文以故意恶意伤害罪的刑罚为主要研究对象,提出了一些量刑推理规则,以限制法官的自由裁量权,提高刑罚的公正性和可执行性。

Chinese keyword extraction based on weighted complex network 基于加权复杂网络的中文关键字提取
Yin-feng Liang
Aiming at the problem of low precision of keyword extraction in traditional complex network method, we propose a keyword extraction method based on an improved weighted complex network, called IWCN algorithm. First, based on the word semantic similarity, we construct a complex network to obtain semantic weight of words. Next, the statistical weight of words is obtained by the introduction of term frequency (TF) and inverse document frequency (IDF). Finally, we combine semantic and statistical weights of words to get keywords. Comparing to traditional complex network approach, the proposed method can avoid the deviations and thus improves extraction accuracy. Simulation results shows that the proposed method achieves higher precision and recall.

Method for determining comprehensive weight vector based on multiple linear fitting 基于多重线性拟合的综合权向量确定方法
Junxuan He, Hailiang Zhao, Yi Jiang
Based on evaluation vectors derived from single factor and the comprehensive evaluation results of some known typical objects, the sample data is classfied into different kinds, and the weight vector of the multi-factor comprehensive evaluation problem is transformed into the solution of an overdetermined systems, which consist of inconsistent linear equation constituted by the vectors of single factor evaluation and the comprehensive evaluation results. The approximate numerical relationship of the standard sample data from the typical objects is fitted with the least squares method, so that the weight vectors to different kinds of objects for comprehensive evaluation are obtained. A learning and correction way to find a multiple linear weighted synthesis model with minimum number of sub-model for the classification of object is presented. A typical object is employed as the center for every sub-model. In applications, the objects are assigned to that class whose center is closest to the objects firstly, and the evaluation result can be derived by the corresponding sub-model. Finally, the effectiveness of the proposed method is illustrated by an example.
基于单因素评价向量和一些已知典型对象的综合评价结果,对样本数据进行分类,将多因素综合评价问题的权重向量转化为一个由单因素评价向量和综合评价结果构成的不一致线性方程组成的过定系统的解。采用最小二乘法拟合典型对象的标准样本数据的近似数值关系,从而得到不同类型对象的权重向量进行综合评价。提出了一种寻找子模型数量最少的多重线性加权综合模型的学习和修正方法。每个子模型都以一个典型对象为中心。在应用中,首先将对象分配到中心离对象最近的类中,通过相应的子模型推导出评价结果。最后,通过算例验证了该方法的有效性。

Comprehensive analysis of retinopathy of prematurity based on tortuosity with development of web connectivity 基于扭曲的早产儿视网膜病变与网络连接的综合分析
Abhishek M. Appaji, H. N. Suma, M. Madhurya, S. Sonia, A. Vinekar
Retinopathy of Prematurity (ROP) is a disease of the eye affecting the prematurely — born babies. It results in unorganized growth of retinal blood vessels which may result in scarring and retinal detachment. The severity of the disease is measured[1] by the stage of the disease and the presence or absence of Plus disease leading to Aggressive Posterior Retinopathy of Prematurity-APROP. The tortuosity index which is indicative of the twisting of the blood vessel calculated. This facilitates in deciding if the new born has APROP or not. A higher value of the index suggests that the baby has developed Plus disease, leading to APROP. The major disadvantage lies in the fact that the number of specialists in Retinopathy are comparatively less. [2] Thus many times this disease goes unnoticed and the baby might be blinded for life. Main objective is to curb the distance between the specialists and the patients in remote area. The importance lies in the fact that the doctor is able to receive the results and can prioritize appointments as per requirements and patients in remote areas can channelize their travel to meet the doctor.
早产儿视网膜病变(ROP)是一种影响早产儿的眼部疾病。它导致视网膜血管的无组织生长,这可能导致疤痕和视网膜脱离。疾病的严重程度是通过疾病的分期和是否存在导致侵袭性早产儿后视网膜病变- aprop的Plus疾病来衡量的[1]。计算血管扭曲程度的扭曲指数。这有助于决定新生儿是否患有APROP。该指数越高,表明婴儿患有Plus疾病,导致APROP。主要的缺点在于视网膜病变专家的数量相对较少。[2]因此,很多时候这种疾病没有被注意到,婴儿可能会终身失明。主要目的是减少偏远地区专家与患者之间的距离。重要的是,医生能够收到结果,并可以根据需要优先安排预约,偏远地区的患者可以通过他们的旅行来满足医生。

On distributivity equations for Mayor's aggregation operators and semi-uninorms 马约尔聚集算子和半一致子的分布性方程
Fengxia Zhang
Distributivity equations has been widely studied involving different classes of aggregation functions from t-norms and t-conorms to various aggregation operators, such as uninorms, t-operators and their generalizations. In this paper, we follow on these works by investigating Mayor's aggregation operators and semi-uninorms.
分配性方程已被广泛研究,涉及不同类别的聚集函数,从t-范数和t-符合到各种聚集算子,如一致子、t算子及其推广。在本文中,我们通过研究Mayor的聚合算子和半一致算子来继承这些工作。
