Reputation of communities of Web services - Preliminary investigation

Web services communities can be seen as virtual clusters that agglomerate Web services with the same functionality (e.g., FlightBooking). However, selecting a community to deal with is a challenging task to users and providers. Reputation, besides other selection criteria, has been widely used for evaluating and ranking candidates. Interestingly, the definition of community reputation from the perspective of users differs from the perspective of Web service providers. In this paper, we introduce a reputation-based Web services community architecture and define some of the petformance metrics that are needed to assess the reputation of a Web service community as perceived by users and providers. © 2008 IEEE

Trust Strategies for the Semantic Web

Everyone agrees on the importance of enabling trust on the SemanticWebto ensure more efficient agent interaction. Current research on trust seems to focus on developing computational models, semantic representations, inference techniques, etc. However, little attention has been given to the plausible trust strategies or tactics that an agent can follow when interacting with other agents on the Semantic Web. In this paper we identify five most common strategies of trust and discuss their envisaged costs and benefits. The aim is to provide some guidelines to help system developers appreciate the risks and gains involved with each trust strategy

Reconsidering online reputation systems

Social and socioeconomic interactions and transactions often require trust. In digital spaces, the main approach to facilitating trust has effectively been to try to reduce or even remove the need for it through the implementation of reputation systems. These generate metrics based on digital data such as ratings and reviews submitted by users, interaction histories, and so on, that are intended to label individuals as more or less reliable or trustworthy in a particular interaction context. We suggest that conventional approaches to the design of such systems are rooted in a capitalist, competitive paradigm, relying on methodological individualism, and that the reputation technologies themselves thus embody and enact this paradigm in whatever space they operate in. We question whether the politics, ethics and philosophy that contribute to this paradigm align with those of some of the contexts in which reputation systems are now being used, and suggest that alternative approaches to the establishment of trust and reputation in digital spaces need to be considered for alternative contexts

Content Reuse and Interest Sharing in Tagging Communities

Tagging communities represent a subclass of a broader class of user-generated content-sharing online communities. In such communities users introduce and tag content for later use. Although recent studies advocate and attempt to harness social knowledge in this context by exploiting collaboration among users, little research has been done to quantify the current level of user collaboration in these communities. This paper introduces two metrics to quantify the level of collaboration: content reuse and shared interest. Using these two metrics, this paper shows that the current level of collaboration in CiteULike and Connotea is consistently low, which significantly limits the potential of harnessing the social knowledge in communities. This study also discusses implications of these findings in the context of recommendation and reputation systems.Comment: 6 pages, 6 figures, AAAI Spring Symposium on Social Information Processin

Quality modeling in electronic healthcare: a study of mHealth Service

Information and communication technologies (ICTs) have the potential to radically transform health services in developing countries. Among various ICT driven health platforms, mobile health is the most promising one because of its widespread penetration and cost effective services. This paper aims to examine Quality Modeling in Electronic Healthcare by using PLS based SEM

From print to Web: issues in re-purposing for an Open Resources Repository

The Open Educational Resources (OER) movement has gained rapid support for its goals of universal access to education. The UK Open University's contribution is OpenLearn, a project funded by the William and Flora Hewlett Foundation which, over the next two years, aims to re-purpose several thousand study-hours of existing learning materials for online delivery. The UK Open University has gained a hard-won reputation for the quality of its learning materials and integrated Supported Open Learning model. However, these materials are, as a rule, developed within the framework of long courses that typically require between 300 and 600 hours of study. Furthermore, many of the courses are 'interdisciplinary' in that they are developed by teams that include members associated with different faculties. The courses are, therefore, generally structured in terms of themes that run throughout the course and may span a variety of academic disciplines. Also, despite the breadth of knowledge brought into play when a course is developed, the courses normally reflect pedagogical and disciplinary assumptions and views that are prevalent in the UK. Based on the authors' experience of the OpenLearn project, this paper explores some of the key issues encountered when re-purposing resources. These issues include how to provide material not supported by tutorial guidance, the suitability of media components for conversion and the inter-relationship between the multimedia components. The paper will also briefly discuss the requirements for evaluation of the re-purposing process. The issues raised are potentially of relevance to other re-purposing initiatives

Users' trust in information resources in the Web environment: a status report

This study has three aims; to provide an overview of the ways in which trust is either assessed or asserted in relation to the use and provision of resources in the Web environment for research and learning; to assess what solutions might be worth further investigation and whether establishing ways to assert trust in academic information resources could assist the development of information literacy; to help increase understanding of how perceptions of trust influence the behaviour of information users

A theoretical model for the application of Web 2.0 in e-Government

Government organisations in many countries have started embracing modern technologies such as second generation web (Web 2.0) in an attempt to maximize on the benefits of these technologies as well as keeping up with the current trend. Nevertheless, the advancement and the adoption of these of technologies is in its initial stages in the public sector. Therefore, the research problem is that the literature surrounding the application of Web 2.0 is still highly tentative and exploratory. In particular, there is a lack of research exploring the application of Web 2.0 technologies in the context of local e-Government. This study aims to address this research problem by presenting a comprehensive decision-making tool to aid the effective application of Web 2.0 technologies amongst local government authorities (LGAs). In doing so, resulting in the development of a theoretical model that is underpinned by information systems evaluation criteria and impact factors of Web 2.0 from an internal organizational perspective. By addressing the research problem, this study will make a significant contribution to the normative literature by providing new insights of Web 2.0 technologies within the public sector. This will be of specific relevance to scholars, policy makers, LGAs and practitioners who are interested in the adoption of Web 2.0 technologies in an e-Government context. This paper presents the proposed theoretical model and is largely devoted to an explanation on the development of the model
