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.     

现代化中的传统道德与传统道德的现代化

如何对待中国传统道德问题 ,是中国现代化过程中不能绕过和回避的现实问题。中国的现代化过程 ,其实也是不断扬弃传统道德的过程。同时 ,传统道德自身也存在着一个自我不断发展的过程 ,实现传统道德自身的现代化 ,是传统道德的必然出路。现代化中的传统道德和传统道德的现代化是一个互动的过程 ,二者相互统一于有中国特色的社会主义现代化的大业之中。     

Tourist number prediction of historic buildings by singular spectrum analysis

A wooden historic building located in Tibet, China, experienced structural damage when subjected to tourists visit. This kind of ancient building attends to too many visitors every day because heritage sites never fail to attract tourists. There should be a balance between accepting the visitors and the protection of historic buildings considering the importance of the cultural relics. In this paper, the singular spectrum analysis (SSA) is used for forecasting the number of tourist for the building management to exercise maintenance measures to the structure. The analyzed results can be used to control the tourist flow to avoid excessive pedestrian loading on the structure. The relationship between the measured acceleration from the structure and the tourist number is firstly studied. The root-mean-square (RMS) value of the measured acceleration in the passage route of the tourist is selected for forecasting future tourist number. The forecasting results from different methods are compared. The SSA is found slightly outperforms the autoregressive integrated moving average model (ARIMA), the X-11-ARIMA model and the cubic spline extrapolation in terms of the RMS error, mean absolute error and mean absolute percentage error for long-term prediction, whereas the opposite is observed for short-term forecasting.     

Breaking the outsourcing path: Backsourcing process and outsourcing lock-in

The objective of this paper is to develop research on backsourcing, which consists in recalling outsourced activities back in-house. We focus on the processes that firms follow to backsource these activities, particularly when they are locked into outsourcing. We refer to path dependence and path creation concepts to conduct this research. Using a case study methodology, we analyze the process related to the backsourcing of information technology activities in a telecommunications company. This paper highlights the negative effects of the need to control outsourced activities as it maintains outsourcing lock-in. Organizational crises and the perception of backsourcing as a success are two elements that enable significant mindful deviations from outsourcing practices and the development of a backsourcing path. The decision to backsource and its implementation can be facilitated by past successful integration experiences, internal productive capabilities, and capabilities to control activities. Changes in power relations within the firm can sustain the development of a backsourcing path. Our research contributes to research on organizational path breaking by studying the backsourcing process as an outsourcing path breaker. This paper complements studies on organizational practices such as outsourcing and backsourcing and their interplay.     

Nonlinear dynamics of the finance-inequality nexus in developing countries

This study examines the dynamics of the finance-inequality nexus in 35 developing countries during the past two decades, using two data sets of income inequality: the University of Texas Inequality Project (UTIP) and the Standardized World Income Inequality Database (SWIID). The empirical results of this study, based on the dynamic panel models, provide new evidence that highlights the nonlinear U-shaped relationship between financial deepening and income distribution. It implies the narrowing of the income-inequality gap at the early stage of financial development of the countries. This improvement, however, will only be sustainable dynamically below a certain threshold level. Further deepening above that level will lead to a reverse effect, which deteriorates income inequality. This reflects the inefficiency of financial markets in improving economic inequality when the threshold level is overshot.

Long‐term Outcomes for Children with Early Language Problems: Beating the Odds

Using the 1970 British Cohort Study, this study examines factors promoting positive language development and subsequent successful education and employment transitions among children showing early receptive language problems (age 5). We find that 61 per cent of children with early receptive language problems develop into competent readers by age 10. Factors promoting positive language development include parental support and more importantly a good school environment, characterised by only few children receiving remedial help. Post‐16 education and employment experiences indicated competent reading to be associated with a less challenging journey into adulthood. Findings are discussed in terms of their policy implications.     

The Effect of Globalization on Financial Development in the MENA Region

This paper provides new evidence that sheds light on the effect of globalization on financial development using data from 9 MENA countries over the period 1991?C2007. The empirical results based on the Panel-data Vector Autoregression and Fully Modified Ordinary Least Squares methods reveal that globalization affects financial development and economic growth in the MENA region while globalization does not play any role in institutional reforms, which promote financial development and economic growth. Hence, governments can play a crucial role in improving the necessary economic conditions for the benefits of globalization to be felt in the MENA region. Also institutional reform policies can be important for policy makers who are attempting to accelerate globalization and financial development.     

Social Bookmarking–Repository–Networking: Possibilities for Support of Teaching and Learning in Higher Education

Abstract

Social bookmarking, repositories, networking, and other Web 2.0 technologies have the capacity to engage enormous numbers of ordinary people in networking, sharing, and working with digital resources. The Faculty of Education at The University of Hong Kong has been pioneering new educational applications. Through grants from the University we have developed a social bookmarking and repository system based on Web 2.0 ideas. RISAL—Repository of Interactive Social Assets for Learning has an unrealized potential to support teaching and learning at the University level. It is designed to facilitate and encourage sharing and collaboration of teachers and students with similar interests or learning foci across levels and programs. This form of learning support builds on and encourages the Web 2.0 culture of social networking and contribution of the individual to the community. In addition, the system is designed to incorporate compliance with Hong Kong's Copyright Ordinance (Creative Commons). The authors discuss the RISAL and describe its features and benefits that this system can offer to teaching and learning.     

Good Passages, Bad Passages

This chapter explores the relation between subjectivities, materialities (including technological arrangements) and bodily competencies. Starting from the assumption that all material and bodily arrangements are specific, it considers some of those specificities, and the 'passages' through which these specific arrangements are fitted together for a particular person, Liv, who is physically disabled. It explores the character of some of Liv's 'passages'—some are 'good', some 'bad', some public, and some discrediting—and the ways in which they are shaped to produce personal and biographical continuity and relative autonomy for her—an autonomy and capacity discretionary decision making which she highly values. The paper thus uses some of the tools developed in the actor-network approach, but also in feminism, to interpret the material and corporeal relations involved in the formation of contemporary subjectivities.
