基于主成分分析的B2C客户分类方法研究

随着电子商务的发展,以"客户为中心"已成为电子商务企业的经营策略,而任何高效的客户关系管理都是以扎实的客户分类为基础。然而电子商务中所搜集到的客户信息往往具有海量、高维度和不完备等特点,如何对其正确、高效地分类是一个难题。根据电子商务客户信息的特点,构建B2C客户分类模型,提出了先对客户信息进行主成分分析以消除属性之间的依赖性,而后用朴素贝叶斯算法进行分类的新方法。实验表明了该方法的有效性。     

Barriers and drivers for non-shoppers in B2C e-commerce: A latent class exploratory analysis

The barriers and drivers of e-shopping, as well as segmentation and behavior of e-shoppers, have been long studied in the last two decades, but the behavior of non-shoppers in business-to-consumer (B2C) e-commerce is still an open field for research which has seldom been dealt with. Our exploratory study has as its main objective the classification of non-shoppers in B2C e-commerce based on the barriers which keep deterring them from purchasing on the Internet and the drivers which might lead them to engage in e-shopping. In order to achieve this goal, data was gathered from 1499 Spanish respondents from a nationwide household panel survey. The responses were analyzed using a latent class analysis (LCA) approach and the results show four different types of non-shoppers based on the barriers for online shopping, while six different groups were identified based on the drivers to start shopping on the Internet. Implications for research and practice from the findings of the study are discussed in the final section.

Business value of B2B electronic commerce: the critical role of inter-firm collaboration

B2B (business-to-business) electronic commerce provides firms with different business value depending on how organizations use the online network. In this paper, we distinguish two different types of B2B e-commerce adoption: basic and collaborative B2B e-commerce. With “basic B2B e-commerce”, firms implement the electronic network simply to automate the exchange of commercial documents. In contrast, B2B networks are used to create new inter-firm operations with channel partners in “collaborative B2B e-commerce.” The central claim of this paper is that firms are unlikely to achieve significant benefits with Basic B2B e-commerce. B2B electronic networks offer dramatic performance improvement only when the B2B network is used to create new collaboration with channel partners. Based on the survey conducted in the grocery industry, this study suggests that the real source of performance improvement in the B2B electronic commerce is not an electronic linkage itself, but the collaboration enabled by the electronic network.     

A growth theory perspective on B2C e-commerce growth in Europe: An exploratory study

Information and communication technologies (ICTs) continue to have a profound effect on the economies and societies where they are used. In this article, we propose three related theories to describe the underlying mechanism for growth in e-commerce revenues at the national level. Endogenous growth theory posits that the primary drivers of e-commerce growth are internal to a country. Exogenous growth theory suggests that the primary drivers of e-commerce growth are external to an economic system, and reflect the forces of the regional economy. A blend of these, a mixed endogenous–exogenous growth theory, incorporates drivers from both the economy and the region of a country. We test a number of hypotheses about e-commerce growth in the context of these theories. The key variables include Internet penetration, telecommunication investment intensity, venture capital and credit card availability, and education level. The data are drawn from 17 European countries over a five-year period from 2000 to 2004, and are analyzed using panel data regression with robust error terms, a variant of weighted least squares. The results show the differential efficacy of internal and external drivers as endogenous and exogenous precursors of e-commerce growth across the countries for a number of different modeling specifications. We conclude with a discussion of alternative approaches to model e-commerce growth in a country. The results also suggest the appropriateness of exploring models of regional contagion for e-commerce growth.     

From business to software: a B2B survey

In recent years business-to-business (B2B) e-commerce has been subject to major rethinking. A paradigm shift can be observed from document centric file-based interchange of business information to process-centric and, finally to service-based information exchange. On a business level, a lot of work has been done to capture business models and collaborative business processes of an enterprise; further initiatives address the identification of customer services and the formalization of business service level agreements (SLA). On a lower, i.e., technical level, the focus is on moving towards service-oriented architectures (SOA). These developments promise more flexibility, a market entry at lower costs and an easier IT-alignment to changing market conditions. This explains the overwhelming quantity of specifications and approaches targeting the area of B2B—these approaches are partly competing and overlapping. In this paper we provide a survey of the most promising approaches at both levels and classify them using the Open-edi reference model standardized by ISO. Whereas on the technical level, service-oriented architecture is becoming the predominant approach, on the business level the landscape is more heterogeneous. In this context, we propose—in line with the services science approach—to integrate business modeling with process modeling in order to make the transformation from business services to Web services more transparent.     

An efficient algorithm of frequent XML query pattern mining for ebXML applications in e-commerce

Providing efficient query to XML data for ebXML applications in e-commerce is crucial, as XML has become the most important technique to exchange data over the Internet. ebXML is a set of specifications for companies to exchange their data in e-commerce. Following the ebXML specifications, companies have a standard method to exchange business messages, communicate data, and business rules in e-commerce. Due to its tree-structure paradigm, XML is superior for its capability of storing and querying complex data for ebXML applications. Therefore, discovering frequent XML query patterns has become an interesting topic for XML data management in ebXML applications. In this paper, we present an efficient mining algorithm, namely ebXMiner, to discover the frequent XML query patterns for ebXML applications. Unlike the existing algorithms, we propose a new idea by collecting the equivalent XML queries and then enumerating the candidates from infrequent XML queries in our ebXMiner. Furthermore, our simulation results show that ebXMiner outperforms other algorithms in its execution time.
