Selected AbstractsQuality of offering on the world wide webINTERNATIONAL JOURNAL OF COMMUNICATION SYSTEMS, Issue 9 2002G. Mantzaridis Abstract The definition of quality in a ,life' environment, such as that of the World Wide Web has proven to have many, often conflicting interpretations. Factors such as the point of view, the expertise and type of usage of the critic can influence dramatically such a definition and its results. Thus, the key point is to distance oneself from single perspectives and obtain a complete picture of the system as a single entity working towards a specific goal. This paper is an attempt at creating a general model of quality procedures. It will concentrate mainly in customer service, system viability and quality of offering evaluation. Some of the material mentioned is based on adapted classical models that can be used equally to apply and observe standards of offerings in the wider WEB community.

[source] Conflict and Intolerance in a Web Community: Effects of a System Integrating Dialogues and MonologuesJOURNAL OF COMPUTER-MEDIATED COMMUNICATION, Issue 3 2007Mitsuharu M. Watanabe The Spiritual Navigator website offers a bulletin board system (BBS) for dialogues, weblogs for individual monologues, and a psychological test so the user can determine his/her own mental state. The results of covariance structure analyses, where questions in the psychological test are the independent variable and the number of postings to the BBS/weblog is the dependent variable, suggest that motivations for BBS interaction and for blogging are quite different. The less tolerant a user is of different views, the more often that user posts to the BBS. Some users who initially post actively to the BBS stop posting there (e.g., in response to criticism) but continue to post to their own weblogs (including their responses to criticism). Given this situation, it is suggested that a system such as the Spiritual Navigator that combines online dialogue and monologue, and that is designed to balance conflicts with stability, could bring about the observance of face-saving ritual (in Goffman's term) or Habermas-like discourse ethics in the public sphere on the Internet. [source] On web communities mining and recommendationCONCURRENCY AND COMPUTATION: PRACTICE & EXPERIENCE, Issue 5 2009Yanchun Zhang Abstract Because of the lack of a uniform schema for web documents and the sheer amount and dynamics of web data, both the effectiveness and the efficiency of information management and retrieval of web data are often unsatisfactory when using conventional data management and searching techniques. To address this issue, we have adopted web mining and web community analysis approaches. On the basis of the analysis of web document contents, hyperlinks analysis, user access logs and semantic analysis, we have developed various approaches or algorithms to construct and analyze web communities, and to make recommendations. This paper will introduce and discuss several approaches on web community mining and recommendation. Copyright © 2009 John Wiley & Sons, Ltd. [source] Approaches for semantic interoperability between domain ontologiesEXPERT SYSTEMS, Issue 3 2008Bhavna Orgun Abstract: Domain ontologies and knowledge-based systems have become very important in the agent and semantic web communities. As their use has increased, providing means of resolving semantic differences has also become very important. In this paper we survey the approaches that have been proposed for providing interoperability among domain ontologies. We also discuss some key issues that still need to be addressed if we are to move from semi-automated to fully automated approaches to providing consensus among heterogeneous ontologies. [source] Interaction strengths in food webs: issues and opportunitiesJOURNAL OF ANIMAL ECOLOGY, Issue 3 2004Eric L. Berlow Summary 1Recent efforts to understand how the patterning of interaction strength affects both structure and dynamics in food webs have highlighted several obstacles to productive synthesis. Issues arise with respect to goals and driving questions, methods and approaches, and placing results in the context of broader ecological theory. 2Much confusion stems from lack of clarity about whether the questions posed relate to community-level patterns or to species dynamics, and to what authors actually mean by the term ,interaction strength'. Here, we describe the various ways in which this term has been applied and discuss the implications of loose terminology and definition for the development of this field. 3Of particular concern is the clear gap between theoretical and empirical investigations of interaction strengths and food web dynamics. The ecological community urgently needs to explore new ways to estimate biologically reasonable model coefficients from empirical data, such as foraging rates, body size, metabolic rate, biomass distribution and other species traits. 4Combining numerical and analytical modelling approaches should allow exploration of the conditions under which different interaction strengths metrics are interchangeable with regard to relative magnitude, system responses, and species identity. 5Finally, the prime focus on predator,prey links in much of the research to date on interaction strengths in food webs has meant that the potential significance of non-trophic interactions, such as competition, facilitation and biotic disturbance, has been largely ignored by the food web community. Such interactions may be important dynamically and should be routinely included in future food web research programmes. [source] | ||||||||||
