中文网络客户评论的产品特征挖掘方法研究

随着互联网的广泛应用,在Blog、BBS、Wiki等网络站点中出现了大量的针对商品或服务的客户评论,这些客户评论中所包含的丰富信息,对企业管理具有重要的价值.通过数据挖掘算法对客户针对某一产品的大量评论进行分析,可以挖掘出这些产品的主要特征,并有望进一步发现客户对这些特征的意见和态度.在英文世界中已经有学者开始对这一研究进行探索,然而由于语言结构等方面的差异,英文的研究成果尚无法直接应用于中文客户评论的挖掘中.本研究针对中文的特点,提出了面向中文的客户评论挖掘方法.该方法基于改进关联规则算法实现了针对中文产品评论的产品特征信息挖掘.本研究采用通过互联网获得的针对手机、数码相机、书籍等5种产品的评论语料,对该方法进行了数据实验,实验结果初步验证了该方法有效性.     

Opportunities of Reforming the WTO: Resistance and Potentials of Change

This paper intends to show both that a reform of the WTO is severely needed in order to establish a fairer international trade order but also that it is possible. The first section of this paper analyzes the functioning and the most controversial rules of the organization. The second and third sections intend to look for current opportunities of reforming the WTO by analyzing the main existing critical responses to the institution’s deficiencies—namely coalitions of southern Nation-States and global civil society movements—and their potential to achieve some change. It is concluded that these two key group actors, while playing different roles, do have common goals on selected issues of international trade and if so, their combined negotiating power is considerably increased for achieving a progress in the direction of a positive reform of the WTO for the developing world.

融合内容分析和关联分析的短生命周期体验品需求特征模式挖掘方法研究

挖掘特定产品的需求模式无法从整体掌握该类产品的市场特征;短生命周期体验品因缺乏历史销售数据,并且销售总量波动性极大,尤其需要从整体掌握销售总量与产品属性间关系的需求特征规律,但又难以挖掘,亟待提出适用于该类产品的需求特征模式挖掘方法。基于按销售总量分区后各区的需求特征的规律性,提出了一种按销售总量分区、以已有产品介绍集和销售总量为源信息、适用于新产品开发前使用、融合内容分析和关联分析的短生命周期体验品需求特征模式挖掘方法。该方法包括基于内容分析法的产品属性挖掘方法和基于关联分析的产品属性关系模式挖掘方法。前者可以得到较全面的产品属性;后者能够构建不同销售总量区间内产品集的属性关系模式,得到各区间的产品属性关系网,获得高销售总量区间具备,但中、低区间不具备的属性关系模式,从而获得需求特征模式。通过不断更新产品介绍集和销售总量并迭代挖掘,该方法能够动态挖掘需求特征模式。最后利用2013至2016年国产犯罪和爱情类电影数据验证了该方法的可行性,并得到了这两类电影的产品属性及近年的需求特征模式,可用于指导这两类电影的创作。     

Organizations in the Public Sector in Hong Kong: Core Government, Quasi-Government and Private Bodies with Public Functions

Twenty-five years ago, the Hong Kong government was lauded as the model of a small, restricted government which was most suited to capitalist economic growth. Since that time, the government and the organizations which it has created have expanded to such an extent that there has been widespread concern that the public sector has grown too large. This article examines the reasons for the rapid growth in the size of the public sector, reflects on the organizational forms outside the traditional civil service that have been adopted, and analyzes the attempts that have been made to reduce the public bureaucracy by corporatizing and privatizing some of the services that it provides. Central to the argument presented is the question of whether an ideological commitment to small government or other functional and political factors have been the critical determinants of organizational change.

On the strengths of the self-updating process clustering algorithm

The self-updating process (SUP) is a clustering algorithm that stands from the viewpoint of data points and simulates the process how data points move and perform self-clustering. It is an iterative process on the sample space and allows for both time-varying and time-invariant operators. By simulations and comparisons, this paper shows that SUP is particularly competitive in clustering (i) data with noise, (ii) data with a large number of clusters, and (iii) unbalanced data. When noise is present in the data, SUP is able to isolate the noise data points while performing clustering simultaneously. The property of the local updating enables SUP to handle data with a large number of clusters and data of various structures. In this paper, we showed that the blurring mean-shift is a static SUP. Therefore, our discussions on the strengths of SUP also apply to the blurring mean-shift.     

The Box–Cox Transformation and Non‐Iterative Estimation Methods for Ordinal Log‐Linear Models

Recently Beh and Farver investigated and evaluated three non‐iterative procedures for estimating the linear‐by‐linear parameter of an ordinal log‐linear model. The study demonstrated that these non‐iterative techniques provide estimates that are, for most types of contingency tables, statistically indistinguishable from estimates from Newton's unidimensional algorithm. Here we show how two of these techniques are related using the Box–Cox transformation. We also show that by using this transformation, accurate non‐iterative estimates are achievable even when a contingency table contains sampling zeros.     

大学生报考公务员动机的探索性研究

通过对574名报考公务员大学生的问卷调查研究表明：大学生在报考公务员时的动机依次为追求工作待遇、缓解就业压力、追求社会地位、追求社会期望、追求权利资源、实现政治抱负、实现素质与职位匹配,并就不同性别、生源地、学校层次对大学生的报考动机进行了比较分析。     

公司章程自治价值分析

理论上,公司章程是公司的宪章,形式上公司章程是公司进行登记、取得公司资格的不可或缺性要件,而实际上,在我国,公司章程并未完全发挥其应有的作用,面临着尴尬的处境。本文首先介绍了自治价值在公司章程中的体现,然后对公司章程现状进行剖析,并提出实现公司章程自治价值的可行性办法。     

论社会公民权的保障——以国家义务的适当承担为出发点

社会福利制度与公民权的结合便形成社会公民权。社会公民权之目的是确保一定的福利水平,使公民过上一种“文明化的生活”。而国家一般通过宪法等形式来确认社会公民权。公民与国家在社会公民权方面的争议可通过社会公民权的适当限制、理性的公众参与以及相应的司法救济予以解决。
