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.

Successful societies: Decision-making and the quality of attentiveness

Combining moral philosophy with sociological theory to build on themes introduced in Hall and Lamont’s Successful Societies (2009), the paper outlines a distinctive perspective. It holds that a necessary condition of successful societies is that decision-makers base their decisions on a high level of attentiveness (concern and comprehension) towards subjectively valued and morally legitimate forms of life. Late modern societies consist of a plurality of forms of life, each providing grounds for what Alasdair MacIntyre has called internal goods—valued and morally valuable practices. The status of such goods is examined, and distinctions are drawn between their manifest and latent, and transposable and situationally specific, characteristics. We integrate this refined idea of internal goods into a developed conception of habitus that is both morally informed and situationally embedded. The sociological approach of strong structuration theory (SST) is employed to demonstrate how this conception of habitus can guide the critique of decision-making that damages internal goods. We identify the most pervasive and invidious forms of damaging decision-making in contemporary societies as those involving excessive forms of instrumental reasoning. We argue that our developed conception of habitus, anchored in the collectively valued practices of specific worlds, can be a powerful focus for resistance. Accounts of scholarship in higher education and of the white working class in America illustrate the specificities of singular, particular, social worlds and illuminate critical challenges raised by the perspective we advocate.     

Risk Communication in The Netherlands: The Monitored Introduction of the EC "Post-Seveso" Directive

Implementation of article 8.1 of the EC-"Seveso" Directive (82/501/EC) is now under way in many countries in Europe. In The Netherlands, the implementation of the Directive started with a carefully monitored introduction of active information provision at two sites (Dordrecht and Elst). This introduction was supported by a multidisciplinary research group. This group helped to develop the risk communication program and also played a role in the evaluation of the program. This paper describes these processes and their evaluation. We will focus on the design of the risk communication programs and the effects of the programs on knowledge and attitudes of the local target groups. This effort and its results clearly started an institutional learning process involving governmental bodies at several organizational levels (local, regional, and national), and industrial organizations (individual firms and organizations of industries). Monitoring the design, the implementation, and the effects of active information provision proves an effective means to gain experience with the implementation of the Seveso Directive and could help to facilitate further implementation.     

Survey investigations of the hidden economy: Some methodological results

In 1982 the Netherlands Central Bureau of Statistics started large-scale survey research on the supply of hidden labour. As it was not known what type of survey would yield the best results, eight survey variants were tried out. They differed in the medium of communication between the researcher and respondent (face-to-face, mail and telephone) and in interview design (direct approach, gradual approach and ‘free-form’ conversation). Several criteria were used to assess the survey variants on their suitability for obtaining statistical information on the magnitude and structure of the hidden labour market. With respect to non-response and item non-response, face-to-face methods yielded the best results. In combating incorrect responses, a gradual introduction of the topic ‘hidden income’ is to be preferred.     

Panel accretion and external validity in adolescent substance use research

This study investigates the relationship of panel accretion to panel attrition and examines its impact on threats to external validity in adolescent substance use research. Panel accretion involves the addition of new participants to a panel design after initial baseline data has been obtained. Accretion occurs in longitudinal studies in which data is routinely gathered on all participants, as is often the case in prevention or epidemiological research on adolescent substance use. Accretion, attrition, and panel findings for three, 2-year panel samples in grades 7 through 9 are examined. The results indicate that accretion and attrition samples have an isomorphic relationship to one another on a range of dependent measures when drawn from the same population. The results are discussed in terms of their implications for adolescent substance use research, the examination of validity threats due to panel bias, and understanding the ecological validity of research findings.     

Were UK Culture, Sport and Recreation Charities Prepared for the 2008 Economic Downturn? An Application of Tuckman and Chang’s Measures of Financial Vulnerability

UK charities experienced rapid growth during the middle years of the first decade of the new millennium. The issue investigated in this study is whether the charities took the opportunity to strengthen their financial positions before the economic recession of 2008–2009. Having evaluated, and established the empirical robustness of, Tuckman and Chang’s measures of financial vulnerability, they are used as the basis for constructing a Charities Financial Exposure Index (CFEI). Variants of the index are applied to a panel of more than 300 large UK charities in the Culture, Sport and Recreation sector for the period 2002–2007. The findings are that by 2008 these charities were in a stronger financial position than they had been in 2002 and were therefore better prepared to face the onset of the so-called credit crunch recession.
