PublicationTrading semantically enhanced digital products in electronic marketsDigital 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.Type: forthcoming

PublicationCarrier Model for Semantically Annotated Information GoodsSharing and trading of information goods requires efficient and effective means for search and evaluation of the content carried by the information goods. The hurdle to overcome is the information paradox according to which, information goods obtain qualities of experience goods. This article describes an approach how ontology-based semantic annotations of infor-mation goods might reduce this paradox. At the centre of this approach is a generic container model called knowledge content object (KCO).Type: conference paper

PublicationAdoption and Diffusion in Electronic Markets: An Empirical Analysis of Attributes influencing the adoption of digital paid contentThe rapid growth of the Internet and electronic commerce stimulates new digital innovations. Electronic markets can influence both the adoption and diffusion processes of digital innovations in significant ways. The difficulties for market transactions of information goods and the change from free to paid content on websites in recent years has led to research questions about how individuals decide whether and when to adopt paid content innovations and how this innovation diffuses throughout a population. This paper presents empirical evidence regarding the adoption and diffusion process of paid content. It focuses on the differences of the adoption and diffusion process of different paid content types dependent on: (1) the existence of established, non-digital counterparts; (2) experience and familiarity with paid content and micropayment services; and (3) economic advantage and perceived convenience. Results pave a ground for a better understanding how paid content will support knowledge work in the futureType: journal articleJournal: Electronic MarketsVolume: 16Issue: 3

PublicationAdoption and Diffusion of Digital Information Goods: An Empirical Analysis of the German Paid Content MarketThe rapid growth of the Internet and electronic commerce stimulates new digital innovations. Electronic markets can influence both adoption and diffusion processes of digital innovations in significant ways. The difficulties for market transactions of information goods and the change from free to paid content on websites in the last years has led to research questions about how individuals decide whether and when to adopt paid content innovations and how this innovation diffuses throughout a population. This article presents empirical evidence about the adoption and diffusion process of paid content. It focuses on the differences of the adoption and diffusion process of different paid content product types if there exists an established, non-digital counterpart. The results in this paper help media managers to design business models for paid content by forecasting the adoption and diffusion process of the offered digital content product.

PublicationTrading digital information goods based on semantic technologiesDigital information goods constitute a growing class of economic goods. During decision making for a purchase a buyer searches for information about digital information goods, such as information about the content, price and trading information, usage information, how it can be presented, and which legal restrictions apply. We present a logical container model for knowledge-intensive digital information goods (knowledge content object - KCO) that directly references formalised semantic descriptions of key information types on information goods. Key information types are formalised as plug-in slots (facets). Facets can be instantiated by semantic descriptions that are linked with domain ontologies. We have identified six logically congruent facet types by which a user can interpret information goods. KCOs are mediated and managed by a technical middleware, called Knowledge Content Carrier Architecture - KCCA. Based on the technical and logical structure of a KCO we will discuss five economic implications that drive further researchType: journal articleJournal: Journal of Theoretical and Applied Electronic Commerce Research (JTAER)Volume: 2Issue: 3

PublicationKnowledge Content Objects and a Knowledge Content Carrier Infrastructure for ambient knowledge and media aware content systemsThe exchange of semantically rich digital content over distributed applications facilitates knowledge exchanges in mixed human / machine environments as envisaged by scenarios within the scope of Ambient Intelligence and Semantic Web. For this class of domain, we introduce a semantically annotated data structure (KCO) and a distributed, layered protocol-based system architecture (KCCA, KCTP) that is designed for loosely coupled, semantically rich content applications. We relate this to requirements of commercial companies for sharing, exchanging and trading knowledge and content. Characteristics of the distributed system architecture are outlined. The argument is that by defining a reasonable set of semantics for manipulating the content objects in question, one offers a stage at which a market of providers and consumers can develop and is facilitatedType: conference paper
