TAILIEUCHUNG - Trading digital information goods based on semantic technologies

In 1978, China had only one bank. This acted both as the central bank and the commercial bank, but today there are six commercial banks, a few regional banks, and urban and rural credit co-operations, as well as the central bank. The further reform in China's financial system is still in progress. Before 1978, there were no advertisements in China, but today advertisements are part of the daily life of China's masses. There are advertising agencies in every province or big city, and television commercials, billboards, newspaper and magazine advertisements can be seen everywhere. The traditional Chinese distribution. | Journal of Theoretical and Applied Electronic Commerce Research ISSN 0718-1876 Electronic version VOL 2 ISSUE 3 DECEMBER 2007 18 - 35 2007 Universidad de Talca - Chile This paper is Available online at Trading digital information goods based on semantic technologies Wolfgang Maass1 Wernher Behrendt2 and Aldo Gangemi3 1 Furtwangen University 2 Salzburg Research Forschungsgesellschaft 3 Institute of Cognitive Sciences and Technology CNR Rome Received 19 December 2006 received in revised form 23 September 2007 accepted 15 October 2007 Abstract Digital 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 research.
