Data Mining for Measuring and Improving the Success of Web Sites

For many companies, competitiveness in e-commerce requires a successful presence on the web. Web sites are used to establish the company's image, to promote and sell goods and to provide customer support. The success of a web site affects and reflects directly the success of the company in the electronic market. In this study, we propose a methodology to improve the success of web sites, based on the exploitation of navigation pattern discovery. In particular, we present a theory, in which success is modelled on the basis of the navigation behaviour of the site's users. We then exploit WUM, a navigation pattern discovery miner, to study how the success of a site is reflected in the users' behaviour. With WUM we measure the success of a site's components and obtain concrete indications of how the site should be improved. We report on our first experiments with an online catalog, the success of which we have studied. Our mining analysis has shown very promising results, on the basis of which the site is currently undergoing concrete improvements.     

结合使用挖掘和内容挖掘的web推荐服务

随着Internet的基础结构不断扩大和其所含信息的持续增长,Internet用户越来越感觉容易在WWW服务中“资源迷向”。提高用户访问效率的方法有页面预取技术,站点动态重构技术和web个性化推荐技术等。现有的大多数web个性化推荐技术主要是基于用户使用记录的数据挖掘方法,没有或很少考虑结合页面内容—这才是用户真正感兴趣的。该文提出一种结合用户使用挖掘和内容挖掘的web推荐服务,该推荐服务根据频繁最大前向访问路径,提出含有导航页和内容页的频繁访问路径图概念,根据滑动窗口内的最近用户访问页面内容和候选推荐集中页面内容相关性,来向用户提供个性化推荐服务。经推荐质量分析,这种方法具有较好的推荐优化能力。

Rewriting-Based Navigation of Web Sites: Looking for Models and Logics

In this paper we outline the use of term rewriting techniques for modeling the dynamic behavior of Web sites. We associate rewrite rules to each Web page expressing the Web pages which are immediately reachable from this page. The obtained system permits the application of well-known results from the rewriting theory to analyse interesting properties of the Web site. In particular, we briefly discuss the use of some logics with strong connections with term rewriting as a basis for specifying and verifying dynamic properties of Web sites. We use Maude as a suitable specification language for such rewriting models which also permits to directly explore interesting dynamic properties of Web sites.

Using company web sites to e-recruit qualified applicants: A job marketing based review of theory-based research

In their rapidly expanding attempts to use company web sites to e-recruit job applicants in a world-wide labor market, employers have often found their hiring systems to be unexpectedly overwhelmed by large numbers of applications from poorly qualified individuals. To both limit and understand this phenomenon, this article employs a job marketing perspective to organize and review contemporary theory-based studies of the effects of web site recruiting sources on job seeker attitudes and employment application behaviors. To accomplish this task, recruiting research based on theoretical elements of Realistic Job Previews (RJPs), Person-Organization (P-O) Fit, the Elaboration Likelihood Model (ELM) and signaling theory is examined in terms of its implications for the ability of companies to e-recruit high quality job applicants. Overall, results of this analysis reveal that each of these theoretical areas offer useful insights but that considerably more theory-based research is needed to assess the effect of e-recruiting sources on the attitudes and decisions of highly qualified job seekers actively engaged in the job search process.     

Factors influencing the Development and Adoption of Knowledge Based Decision Support Systems for Small,Owner-Operated Rural Business

This paper provides an analysis of existing literature and practical problems associated with the adoption of a developed knowledge-based decision support system (KBDSS) within small rural businesses. The rural small businesses selected for this study were individual farms within the Australian dairy industry and the developed KBDSS was called DairyPro. The object was to determine the factors that could help with future KBDSS development and improve adoption rates. These factors were tested against DairyPro to determine their effectiveness. This analysis indicates that system developers need to have a good working knowledge of the target industry and to understand the types of decisions that are made by managers in order to develop systems that will be used. A review of the literature also suggests that adoption rates can be influenced by cultural, political, educational and age factors as well as individual characteristics of information technology itself. Small business managers needed more ownership in the process of KBDSS development. The author suggests that the factors affecting KBDSS adoption by dairy farmers can be equally applicable to other small, owner-operated rural businesses. This approach advocates the use of domain experts to provide estimates of expected production levels rather than that of the traditional approach of using the results from mathematical or simulation models to make these estimates.     

针对小文本的Web数据挖掘技术及其应用

现有搜索引擎技术返回给用户的信息太多太杂,为此提出一种针对小文本的基于近似网页聚类算法的Web文本数据挖掘技术,该技术根据用户的兴趣程度形成词汇库,利用模糊聚类方法获得分词词典组,采用MD5算法去除重复页面,采用近似网页聚类算法对剩余页面聚类,并用马尔可夫Web序列挖掘算法对聚类结果排序,从而提供用户感兴趣的网页簇序列,使用户可以迅速找到感兴趣的页面。实验证明该算法在保证查全率和查准率的基础上大大提高了搜索效率。由于是针对小文本的数据挖掘,所研究的算法时间和空间复杂度都不高,因此有望成为一种实用、有效的信息检索技术。     

Web sites of the Fortune 500 companies: Facing customers through home pages

The growing popularity of the information superhighway has opened up exciting opportunities for companies looking to, not only maintain their current customer base, but also to reach new customers. One of the most popular methods to enter into cybermarketing has been to establish a home page or Web site on the Internet. Almost two-thirds of Fortune 500 companies currently maintain home pages on the Web. An analysis of the content of corporate home pages provides useful insights. Over four-fifths of the companies display products and services (93.2%) and company overview (86.1%) information. Roughly three-fourths of the companies present interactive feedback (79.3%) and what's new (71.1%). Less than one-third (26.2%) of Fortune 500 companies provide for online business. An analysis of the data also provides valuable insight into the future trends of home page usage by large business organizations.

Entity-Centric Operations Modeling for Business Process Management: A Multidisciplinary Review of the State-of-the-Art

The entity-based approach for operations modeling was published for the first time three decades ago. Specifically, the notion of entities as the main subjects of processes and entity life-cycle as a technique for dynamic modeling of operations were introduced independently by K. Robinson in 1979, C. Rosenquist in 1982 and M. Jackson in 1983. This modeling work emerged in clear contrast with static entity-relationship modeling found in the data-base tradition. These three pioneer contributions and other substantial research done at the realm of information engineering, structured systems analysis and social sciences in the 80''s and 90''s have established an important foundation for business operations modeling. On the other hand, Business Process Management (BPM) has continued to receive great attention from practitioners and scholars. Being one of the main hinges between theory and practice of business operations, BPM enjoys contributions from several domains of research such as economics, social sciences, engineering and computing. In spite of its steady growth, the industry side of BPM seems to have evolved somewhat unaware of related progress in the above sister disciplines. Specifically, recent claims on the need to integrate information and activities in process modeling and some rediscoveries of core ideas from entity-based dynamic modeling offer some examples of the disconnection. These and other findings suggest that the BPM field may not have yet fully benefited from the work done in the tradition of structured analysis, information engineering and process theory schools. Furthermore, the possibility of using entity life-cycle for modeling operations addressed by Case Management is an important byproduct. Entity-based life cycle offers a conceptual framework to integrate different types of enterprise operations whose modeling has not yet been reconciled in the BPM tradition. This paper presents an in-depth, multidisciplinary review of the state-of-the-art on entity life cycle modeling. The focus of this review is exclusively on modeling concepts and methodology while tools, programming models and other aspects of entity-life life cycle implementation will be addressed in companion papers. This review should also help pave more holistic approaches to business process modeling.     

Web search engine: Characteristics of user behaviors and their implication

In this paper, first studied are the distribution characteristics of user behaviors based on log data from a massive web search engine. Analysis shows that stochastic distribution of user queries accords with the characteristics of power-law function and exhibits strong similarity, and the user' s queries and clicked URLs present dramatic locality, which implies that query cache and 'hot click' cache can be employed to improve system performance. Then three typical cache replacement policies are compared, including LRU, FIFO, and LFU with attenuation. In addition, the distribution character-istics of web information are also analyzed, which demonstrates that the link popularity and replica pop-ularity of a URL have positive influence on its importance. Finally, variance between the link popularity and user popularity, and variance between replica popularity and user popularity are analyzed, which give us some important insight that helps us improve the ranking algorithms in a search engine.
