Taking into consideration technology acceptance factors, website service quality and specific holdup cost factors, this research explores how shopping websites to establish their competitive advantages through these dimensions. We begin with an examination of the literature on shopping websites about its competitive advantages upon which we propose a conceptual framework. Then this research adopts the fuzzy TOPSIS as the analytical tool that determines the weights of each criterion. Fuzzy theory provides a proper tool to encounter with uncertainties and complex environment. The purpose of this paper is to use the fuzzy TOPSIS method based on fuzzy sets in solving MCDM problems. From our research results, the security and trust are the most important factors for improving the competitive advantage of shopping website. Moreover, the PCHome and Yahoo Taiwan rank the first two positions for shopping websites. This paper draws on the research results for implications of managerial practice, and then suggests some empirical tactics in order to enhance management performance for the website shopping industry.  相似文献

In the wake of the rapid emergence of e-commerce, its evaluation is of great theoretical and practical importance. Among the various types of e-commerce, business-to-consumer (B2C) e-commerce has become a key, and especially influential, retailing channel. Its ascendancy raises core issues with respect to how the customer is to be satisfied by, and therefore inclined to trust, e-commerce websites. B2C e-commerce website evaluation, therefore, is an important related issue. First, while a number of studies have studied B2C e-commerce website evaluation using various multiple-criteria-decision-making (MCDM) methods, they have focused only on the perceived service quality of B2C e-commerce websites. In fact, it is generally recognized that service quality is determined by the difference between the expected service level (which expectation is derived from information obtained before the service experience) and the actual, perceived service level; this concept, then, should be also be afforded due consideration in B2C e-commerce website evaluation. Second, among the various MCDM approaches, TOPSIS, which involves the consideration of both the positive-ideal solution (PIS) and the negative-ideal solution (NIS), is especially pertinent to the complex decision-making entailed in the evaluation of B2C e-commerce websites. Third, the human element of subjectivity in the evaluation of B2C e-commerce websites needs to be considered in order to enable modeling of real-life website-evaluation situations. Finally, the hierarchical structure of the evaluation criteria between the main dimensions and their sub-criteria should be considered. To reflect these issues, in this paper, we present a fuzzy hierarchical TOPSIS based on E-SERVQUAL (E-S-QUAL). This approach effectively considers the raised issues and preserves the core concept of E-S-QUAL (the extended version of SERVQUAL) for measurement of electronic service quality in the e-commerce environment. The empirical case study of B2C e-commerce provides the researchers and practitioners to understand in a better way the evaluation process from a practical point of view. In addition, core finding of this study is that the comparison results with other MCDM methods further verify the robustness of the proposed approach. It implies that this method potentially can be applied to performance evaluation of similar service sectors.  相似文献

Over the past few years, more and more Internet visitors are reaching websites through search engines rather than through direct links from another web page. Search engines have come to occupy a prominent position in the online world and are being used to find all kinds of information including things, events, people, and places. The search engine is also coming to play a greater role as a critical link between firms that use the Internet to build their image and find their target customers. How to achieve a high ranking in such search results given certain search words or phrases has become an issue of much interest in Internet marketing. The purpose of the current study is to develop a search engine optimization (SEO) mechanism that can be used by an enterprise to improve the ranking of its website in the search engine results. Social networking sites are included in our exploration of Internet marketing strategy. The proposed mechanism is then applied in the operations of an online ebook store. The website rankings obtained from two well‐known online search engines (Google and Yahoo) are evaluated in efforts to explore a better strategy to ensure higher rankings. The results reveal that a well‐designed SEO strategy, with the incorporation of social networking, can effectively enhance the website's visibility and exposure. Such a strategy will eventually contribute to overall site traffic and improve interaction with customers. © 2012 Wiley Periodicals, Inc.  相似文献

Technology credit scoring models have been used to screen loan applicant firms based on their technology. Typically a logistic regression model is employed to relate the probability of a loan default of the firms with several evaluation attributes associated with technology. However, these attributes are evaluated in linguistic expressions represented by fuzzy number. Besides, the possibility of loan default can be described in verbal terms as well. To handle these fuzzy input and output data, we proposed a fuzzy credit scoring model that can be applied to predict the default possibility of loan for a firm that is approved based on its technology. The method of fuzzy logistic regression as an appropriate prediction approach for credit scoring with fuzzy input and output was presented in this study. The performance of the model is improved compared to that of typical logistic regression. This study is expected to contribute to practical utilization of the technology credit scoring with linguistic evaluation attributes.  相似文献

The Internet is increasingly a source of information for populations around the world, and thus theorizing that website design, which leads to enhanced recall of web-based information, has important theoretical and practical implications. On the basis of evolutionary psychology, biophilia and biophobia theories show how humans developed emotional responses to aspects of their natural environments so as to enhance survival by triggering approach or avoidance behaviors. Enhanced memory for biophobic elements such as predators and biophilic elements such as food would be further fitness enhancing. This study aimed to show how website design based on biophilia and biophobia theories can elicit emotions and improve recall of web-based information. An experiment was performed with simulated national park websites that contained images designed to elicit emotional responses. The emotional responses (e.g., valence and arousal) were associated with increased recall of information presented on the websites. The study contributes by showing that biophilia theory and biophobic theory can guide website design research and improve information recall.  相似文献

网站指纹技术能够让本地监听者通过审查用户与Tor入口节点之间的匿名流量从而追踪到该用户访问的具体网站。现有的研究方法只提取了匿名流量中的部分元数据来进行网站指纹的刻画,忽视了大量隐含的指纹信息。为此,提出了基于图像纹理和深度卷积神经网络的网站指纹技术Image-FP。首先,将匿名通信流量映射成RGB彩色图;然后,使用残差神经网络(ResNet)构造出能进行自主特征学习的网站指纹分类模型。在50个网站构成的封闭世界场景下,Image-FP能够取得97.2%的分类准确率,相较于最前沿的网站指纹攻击技术提高了0.4个百分点。而在更接近真实环境的开放世界场景中,Image-FP能够以100%的准确率识别出监控网站的流量,其准确性和鲁棒性更是远远高于其他指纹技术。实验结果表明,匿名流量图像化的技术能够更多地保留网站指纹的相关特征,并且在避免复杂特征工程的同时,能够进一步提高分类精度  相似文献

Nowadays, the patients and physicians use the health-related websites as an important information source and, therefore, it is critical the quality evaluation of health- related websites. The quality assessment of health-related websites becomes especially relevant because their use imply the existence of a wide range of threats which can affect people’s health. Additionally, website quality evaluation can also contribute to maximize the exploitation of invested resources by organizations in the development of user-perceived quality websites. But there is not yet a clear and unambiguous definition of the concept of website quality and the debate about quality evaluation on the Web remains open. In this paper, we present a qualitative and user-oriented methodology for assessing quality of health-related websites based on a 2-tuple fuzzy linguistic approach. To identify the quality criteria set, a qualitative research has been carried out using the focus groups technique. The measurement method generates linguistic quality assessments considering the visitors’ judgements with respect to those quality criteria. The combination of the linguistic judgements is implemented without a loss of information by applying a 2-tuple linguistic weighted average operator. This methodology means an improvement on quality evaluation of health websites through the commitment to put users first.  相似文献

A hybrid ANP evaluation model for electronic service quality   总被引:2,自引:0,他引:2  
Previous research has developed evaluation measurement for electronic service quality (e-SQ) but has ignored the interdependence perspective of the criteria and sub-criteria for e-SQ evaluation. Therefore, this study aims to propose a hybrid analytic network process (ANP) model as an improved method to evaluate multiple-criteria and sub-criteria of e-SQ with the interdependence perspective. This hybrid ANP model was proposed by utilizing a process of algorithm that combines the consistent fuzzy preference relations method with the ANP approach to evaluate e-SQ. Moreover, this model overcame the problems while using the ANP in ranking options during multiple-criteria decision-making, such as the lack of consistency, the complexity, and the inability to handle information uncertainty. By using online travel websites as empirical application, this study demonstrated the hybrid ANP evaluation model that could capture expert's knowledge existing in the form of incomplete and vague information as well as identify the most important criteria based on interdependent perspective when evaluating e-SQ for websites. The results indicated that the interdependence perspective among criteria and sub-criteria should be taken into consideration by practitioners looking to improve their e-SQ. This study also suggested practitioners who manage websites that is sufficient and necessary to evaluate e-SQ under considered interdependence perspective for criteria and sub-criteria in order to obtain more in-depth findings and potential knowledge to discover the truly important criteria and sub-criteria of e-SQ when improving quality of websites. Such efforts will create overall improvement instead of isolated improvements in individual areas.  相似文献

Based on the development of the use of websites by brands, the purpose of this paper is to identify and describe different groups of luxury brands bearing in mind the persuasiveness of their websites (informativeness, usability, credibility, inspiration, involvement and reciprocity). The data for this study were collected from 197 luxury websites through content analysis methodology. Then, latent class cluster analysis was employed to identify the segments obtained in this study. The results confirm the existence of three segments of luxury brands according to website persuasiveness: “exclusive websites”, “transparent and accessible websites” and “old-fashioned websites”. This study helps luxury brand managers to evaluate the degree of persuasiveness of each group, determines how attractive the websites in each group are and suggests the measures necessary to improve their websites.  相似文献
