The already huge number of blogs in existence is increasing rapidly, and many users are struggling to find a way to keep up with the expansion. A number of existing tools aim to capture the general topics of all currently popular topics among the entire blogosphere, while others allow individuals to read a fixed list of blogs. However, few personalized tools exist to help the individual get an overview of the specific blogs he or she reads. This paper presents the concept of social topic extraction via the Smarter Blogroll, which displays current topics for a selection of blogs. While there was little difference in users' ability to identify topics using the smarter blogroll, the results of our user study point to design recommendations for improving the use of metadata within blogroll entries, thereby facilitating blog reading. The paper concludes with implications for the design of tools to aid in blog navigation and reading, as well as recommended directions for future research.

The core vector machine (CVM) has been introduced as an extremely fast classifier which is demonstrably superior to standard support vector machines (SVMs) on very large datasets. However, only limited information regarding the suitability of CVM for supporting corporate planning is available so far. In this paper, we strive to overcome this deficit. In particular, we consider customer-centric data mining which commonly involves classification in medium-sized settings. CVMs are compared to SVMs within the scope of an empirical benchmarking study to clarify whether previous findings regarding the competitiveness of CVMs generalize to business applications. To that end, representative real-world datasets are employed. In addition, the study aims at scrutinizing the behavior of CVM during model selection. Following a standard grid-search based approach we find some evidence for CVM being more sensitive towards parameter settings than SVMs.

Interest in mobile computing applications has been increasing over the past few years. The Healthcare sector has recognized the potential for providing at "point-of-care" access to applications through mobile devices. The business value of the implementation of information technology (IT) has been studied from various perspectives. This paper explores the value of the implementation of mobile computing on the efficiency and effectiveness of an Emergency Medical Services organization in Australia. The research question that is addressed in this paper is: In what way do mobile systems deliver internal value in emergency healthcare organizations? The paper evaluates the responses by various stakeholders in an Australian Emergency Service organization. The paper makes the following three contributions. First, the case study indicates that the introduction of mobile systems can support ambulance services in providing more efficient and effective information that could potentially impact on their performance evaluation. Second. a number of advantages of the mobile system for emergency services are highlighted. Third, a delicate balance between internal data capture requirements versus external requirements of readability of the final electronic Patient Care Record is highlighted.

This project uses empirical data to provide insights into the impact of open standards. This work moves beyond the existing literature by considering a large number of open standards, instead of handpicked case studies. The results of this research will be timely, as governments are advocating and sometimes mandating the use of open standards. We found inequalities in the impact of open standards that suggest a power law relationship, found that the duration of the development process does not affect the impact of a standard, and found the length of a standard (number of words), which reflects the technical complexity of a standard, affects the impact of a standard.

The knowledge of the positions of the different members in a group decision situation is used in a prototype of a group decision support tool that explicitly computes and presents the differences between the individual positions held by each group member to help the group describe and define the parameters of the decision problem. A collaboration model based on two stages, one of group structuring (communication), and one of individual discrimination (appropriation) is proposed. These stages alternate as each individual learns about other group members preferences, to accommodate other inputs and preferences, or to explore the problem. Information regarding the sources of disagreement between group members' positions and the changes that would be needed to achieve equal results are provided by the system, to help achieve a common solution (if possible).

Individual users are known to differ in their tendency to adopt new technologies. Among the individual differences, Personal Innovativeness in IT (PUT) has been shown to be a reliable predictor of users' beliefs about the ease of use and usefulness of new technologies. However, it is unclear what are the personality traits that make some users more innovative in IT than others. Personality traits are used in the psychology literature to explain human beliefs and behavior, and recently see a growing interest in the IS literature as an explanatory tool of user behavior. The present research investigates two personality traits established in the psychology literature, resistance to change (RTC) and Openness, as determinants of PUT A survey of 121 prospective users of a digital library system was conducted to test our hypotheses. The findings suggest that RTC and Openness are determinants of PUT Implications for research and practice are discussed.

Recently [1] presented a new model for the solution of the water distribution network problem. The model captured successfully the essence of the problem structure, but could not guarantee global convergence. This paper adds, to the current research track, a new model and method that can guarantee global convergence for the water network design problem. The contribution is important since there has not been any effort to find methods ensuring global convergence and the solutions found to several example problems in earlier contributions are not qualitatively established.

In the context of decision support systems, a model management system (MMS) is analogous to a database management system providing support for the various phases of a modeling life-cycle while insulating user from the physical aspects of model base storage and processing. An underlying premise is the recognition of models as a resource that need to be managed and modeling as an activity that need to be supported within organizations. The recent developments of the Web and distributed computing environments is creating ever increasing demands for sharing and reusing heterogeneous models over corporate intranets and the Internet. To this end, this paper presents a semantic Web services-based architecture for MMS. The architecture is based on service-oriented principles and web services standards to support model sharing and reuse in a distributed environment. Integral to the architecture is the use of ontologies and artificial intelligence (AI) planning techniques to facilitate model composition. We demonstrate the features and advantages of the proposed architecture using representative examples. We conclude with a discussion of the current state of implementation and plans for future work.

Today, the means for attaining competitive advantage with information technology (IT) has shifted from efficiently managing the organization's operations to discovering ways to collaborate with industry partners to provide products and services to markets that are otherwise uneconomical to pursue. Current IT challenges center on ways to integrate diverse systems into function rich business processes that span organizational boundaries. Though service oriented architecture (SOA) is poised to become a mainstream technology, its success may hinge on a meeting of the minds between the architects and developers of Web services and business process modelers who map out corporate requirements. This paper defines SOA, discusses how SOA relates to business process management, and provides an illustration of enterprise SOA applied in an enterprise resource planning (ERP) environment. The paper also describes how SOA motivates change in IT governance, enumerates the fundamentals of SOA success, and reflects on implications for IT education.

Personalization is a phenomenon that intrigues and confuses. Personalized offerings promise customer attention, loyalty and safe haven against commoditization. However, these promises do not materialize unless customers accept personalization as a means to enhance their consuming experience. Three points of views are offered to personalization in this paper. An analysis of various personalization concepts shows that the basic concept of personalization is reaching maturity even though fresh views are added to it, e.g. context-based personalization. Secondly, a text-mining based approach profiles the personalization research based on bibliometric data on nearly 800 articles, and indicates that the research field is fairly fragmented, and that mass customization and customization research clearly diverges from personalization research. Based on a selection of articles, a further analysis classifies the type of research and research contexts that are the most common. Finally, this research also suggests a conceptualization of personalization.
