- KonferenzbeitragTrading semantically enhanced digital products in electronic markets(Pragmatic web – Proceedings of the first international conference on the pragmatic web, 2006, 2006) Maass, Wolfgang; Behrendt, WernherDigital products constitute a growing class of economic goods that are increasingly traded via digital networks. In distributed digital networks, it is required that digital products adapt to heterogeneous requirements of electronic markets and subsequent usage environments. Adaptation depends on various kinds of information types that characterise a digital product. In this article we will present a self-describing container model for digital products, called KCO, that integrates characteristic semantic information types (facets) derived from an analysis of electronic market structures. Semantic information supports usage of digital products throughout the whole product life-cycle. During purchase decision phases, facets offer semantically annotated data on the quality and applicability of a digital product while in usage contexts, facets provide data that can be used by content management systems for content processing tasks, such as access control, routing, syndication and aggregration. KCOs allow exchanges between existing heterogeneous application environments on the basis of an open Knowledge Content Transfer Protocol (KCTP) that is part of a general architecture (Knowledge Content Carrier Architecture, KCCA). All architectural elements have been used in three application environments.1
- KonferenzbeitragCan the pragmatic web assist search engine optimisation?(Pragmatic web – Proceedings of the first international conference on the pragmatic web, 2006, 2006) Razafimbelo, Tiana; Polovina, Simon; Hill, RichardDiscovering information on the Web relies on the publishers of that information to describe it in a meaningful way, often at the syntactical level. Despite ongoing efforts to improve Web page description, search retrieval is more time consuming than it should be. Essentially this arises because search engines lack the capacity to identify the purpose of the search. The goal of this paper is to identify the extent to which this issue can be addressed and how the Pragmatic Web may assist in this endeavour. The paper uses Stamper's Semiotic Ladder to distinguish between those issues that are truly semantic, pragmatic or even social, versus those which are syntactic. This enables the core issues to be discovered, thereby distinguishing the areas that the Pragmatic Web community can focus upon.
- KonferenzbeitragArchitecture of a semantic portal on mobile business(Pragmatic web – Proceedings of the first international conference on the pragmatic web, 2006, 2006) Krybus, Ilja; Kurbel, KarlPortals on the web are important public sources of information for expert knowledge. They function as powerful gateways that consolidate access and organize information. Existing web technologies provide the means which most current web portals apply. However, they leave some open issues that recent Semantic Web technologies promise to solve. Portals that employ semantic technologies are called semantic portals. In this paper, we present the synopsis of a semantic portal that is dedicated to distributing practical and scientific knowledge on the domain of Mobile Business. We explain the motivation, the architectural considerations, and the current portal prototype. Emphasis is placed on ontology use, request processing, and presentation. The advantages of our process-oriented and multilayered architecture approach are discussed.
- KonferenzbeitragA policy framework for collaborative web service customization(Pragmatic web – Proceedings of the first international conference on the pragmatic web, 2006, 2006) Liang, Haiqi; Sun, Wei; Zhang, Xin; Jiang, ZhongboA web service usually serves many consumers, with each consumer having its specific functional or nonfunctional requirements. The web service should be customizable to meet those requirements, as is especially apparent for complex web services with large granularity such as Softwareas-Service (SaS). This paper proposes an approach to facilitating web service customization in the programatical way through the collaboration between service provider and consumer. A specification for declaring web service customization policy is defined based on the WS-Policy framework, through which service provider can declare the service's customization capabilities. A service consumer can make customization requests within the scope defined by the customization policies. The customization requests are raised in structuralized customization directives. A web service consumption process and a supporting framework accompanied with customization policy are introduced accordingly. Finally, a case study is present.
- KonferenzbeitragPragmatic web as communication design practice(Pragmatic web – Proceedings of the first international conference on the pragmatic web, 2006, 2006) Aakhus, MarkThe Pragmatic Web is seen as a direction for realizing the vision of the Semantic Web. Realizing the vision of the Pragmatic Web, however, requires a shift in thinking about technology as a means for designing communication (which is making forms of interactivity possible that may otherwise be difficult or impossible). Some lessons from theory and research on Pragmatics provide grounds for understanding how technology plays a role in constructing contexts of interactivity. Similar to ordinary interaction strategies and the intervention practices of communication professionals, technologies provide ways to solve the practical puzzles of action, meaning, and coherence in interaction. Technologies are hypotheses about solving interactional problems that are built on assumptions about how interaction works and ought to work. To better understand the Pragmatic Web it is necessary to articulate and assess these assumptions. Two plausible, complementary approaches are suggested.
- KonferenzbeitragSensemaking on the pragmatic web: A hypermedia discourse perspective(Pragmatic web – Proceedings of the first international conference on the pragmatic web, 2006, 2006) Shu, Simon J. BuckinghamThe complexity of the dilemmas we face on an organizational, societal and global scale forces us into sensemaking activity. We need tools for expressing and contesting perspectives flexible enough for real time use in meetings, structured enough to help manage longer term memory, and powerful enough to filter the complexity of extended deliberation and debate on an organizational or global scale. This has been the motivation for a programme of basic and applied action research into Hypermedia Discourse, which draws on research in hypertext, information visualization, argumentation, modelling, and meeting facilitation. This paper proposes that this strand of work shares a key principle behind the Pragmatic Web concept, namely, the need to take seriously diverse perspectives and the processes of meaning negotiation. Moreover, it is argued that the hypermedia discourse tools described instantiate this principle in practical tools which permit end-user control over modelling approaches in the absence of consensus.
- KonferenzbeitragCharacteristics of public E-services: Investigating the E-diamond model(Pragmatic web – Proceedings of the first international conference on the pragmatic web, 2006, 2006) Goldkuhl, Göran; Persson, AndersThe issue of the paper is how to characterize public e-services mediated through the web. One common kind of characterization is made through stage models (e-ladders). Such models are frequently used for policy-planning, evaluation and bench-marking of public e-services. E-ladder models have been criticized and as an alternative the e-diamond model has been formulated, which consists of twelve categories in three polarities (informative vs performative; general vs individualized; separate vs coordinated). The differences between e-ladder and e-diamond models are described in the paper. Empirical investigations of some public e-services based on the e-diamond model are pursued. A theoretical analysis of the e-diamond model based on the language-action perspective is performed. This follows the view that public e-services are seen as government – citizen communication. The empirical and theoretical investigations give further support to the e-diamond model.
- KonferenzbeitragThe role of virtual servants in e-Interaction(Pragmatic web – Proceedings of the first international conference on the pragmatic web, 2006, 2006) Lind, Mikael; Salomonson, NicklasInternet-based interfaces between organisations and their buyers are becoming increasingly common. Lately virtual servants have been identified as agents to support the customer – supplier interaction. In this paper we investigate the existence of one such virtual servant – Anna at IKEA.com – in a business interaction situation. Anna is regarded as an example of a typical virtual servant of today. Based on pragmatic theories for business interaction we investigate the role of this virtual servant. The conclusion from this study shows that this virtual servant does support the potential / particular buyer in navigating on the company's web-site rather than the realisation of a purchase.
- KonferenzbeitragSupporting global software development in open source ecosystems: A role for actability in the pragmatic web(Pragmatic web – Proceedings of the first international conference on the pragmatic web, 2006, 2006) Ågerfalk, Pär J.New forms of collaboration between organizations based on open source principles are rapidly emerging. The collaboration is typically done in a spirit of co-opetition whereby companies, often SMEs, share cost and risk by developing software jointly and openly. The paper elaborates how this emerging phenomenon of open source ecosystems can be understood from the perspective of actability and the Pragmatic Web. The concept of open source ecosystems as a form of global software development is explored and actability is presented as a useful concept for articulating design criteria for the required collaborative tools. In doing so, a possible research agenda for pragmatic web research in this domain is outlined.
