A Configurable Matchmaking Framework for Electronic Marketplaces

E-marketplaces constitute a major enabler of B2B and B2C e-commerce activities. This paper proposes a framework for one of the central activities of e-marketplaces: matchmaking of trading intentions lodged by market participants. The framework identifies a core set of concepts and functions that are common to all types of marketplaces and can serve as the basis for describing the distinct styles of matchmaking employed within various market mechanisms. A prototype implementation of the framework based on Web services technology is presented, illustrating its ability to be dynamically configured to meet specific market needs and its potential to serve as a foundation for more fully fledged e-marketplace frameworks

Leveraging Offshore IT Outsourcing by SMEs through Online Marketplaces

Following their larger counterparts, an increasing number of small firms outsource their IT tasks to lower cost offshore destinations. For small firms, however, offshore outsourcing is a difficult undertaking as it involves high transaction costs. Online marketplaces for IT services, which have recently become available to small firms, make offshore IT outsourcing more accessible and manageable, although differences in the marketplace design result in varying outcomes across the marketplaces. This has consequences for SME’s decision as to which online marketplace to use, because different markets may have different types of benefits and costs. This paper sets to analyze some of the similarities and differences between online marketplaces for IT services and their effects for small firms. First, we analyze if and how online marketplaces reduce small firms’ transaction costs in offshore IT outsourcing. Second, we examine the effects of market entry barriers on outcomes of online marketplaces and their implications for small firms. The results indicate that online marketplaces for IT services do reduce transaction costs for small firms in offshore outsourcing across ten specific market processes. More surprising, however, is the finding that the lower market entry barriers for suppliers result in lower prices for buyers without compromising other aspects of market performance.Offshore IT Outsourcing;Online Market;Process-Stakeholder Analysis;Reverse Auction

Organising the knowledge space for software components

Software development has become a distributed, collaborative process based on the assembly of off-the-shelf and purpose-built components. The selection of software components from component repositories and the development of components for these repositories requires an accessible information infrastructure that allows the description and comparison of these components. General knowledge relating to software development is equally important in this context as knowledge concerning the application domain of the software. Both form two pillars on which the structural and behavioural properties of software components can be addressed. Form, effect, and intention are the essential aspects of process-based knowledge representation with behaviour as a primary property. We investigate how this information space for software components can be organised in order to facilitate the required taxonomy, thesaurus, conceptual model, and logical framework functions. Focal point is an axiomatised ontology that, in addition to the usual static view on knowledge, also intrinsically addresses the dynamics, i.e. the behaviour of software. Modal logics are central here – providing a bridge between classical (static) knowledge representation approaches and behaviour and process description and classification. We relate our discussion to the Web context, looking at Web services as components and the Semantic Web as the knowledge representation framewor

The Economic Impacts of Information and Communication Technology In The Hungarian Economy

As the author could not find a reassuring mathematical and statistical method in the literature for studying the effect of information communication technology on enterprises, the author suggested a new research and analysis method that he also used to study the Hungarian economic sectors. After a brief introduction to the theoretical background of the Information Age, the author examines the question of what factors have an effect on their net income is essential for enterprises. First, the potential indicators related to economic sectors were studied, then the author compared those indicators to the net income of the surveyed enterprises. The data resulting from the comparison showed that the growing penetration of electronic marketplaces contributed to the change of the net income of enterprises in various economic sectors to the extent of 37 %. Among all the potential indicators, only the indicator of electronic marketplaces has a direct influence on the net income of enterprises. It was practical to determine two clusters based on the potential indicators

An Empirical Study of the Development of Information and Communication Technology in Hungary

As I could not find a reliable mathematical and statistical method for studying the effect of information communication technology on businesses in the literature, I proposed a new research and analysis method that I also used to study the Hungarian economic sectors. An essential question for enterprises is what factors have an effect on their net income.. First, I studied the potential indicators related to economic sectors, then I compared those indicators to the net income of the enterprises surveyed. The data resulting from this comparison showed that the growing penetration of electronic marketpalces contributed to the change in the net income of enterprises in various Hungarian economic sectors to the extent of 37%. Among all the potential indicators, only the indicator of electronic marketplaces has a direct influence on the net income of enterprises. However, the effect of electronic presence is also significant as it has a huge effect on the potential indicator of electronic marketplaces. It was practical to determine two clusters based on the potential indicators. Eight economic sectors have been placed in the first, while five sectors have been placed in the second cluster. Only the money which is spent on professional training has a more significant effect on what cluster a sector belongs to

Knowledge infrastructures for software service architectures

Software development has become a distributed, collaborative process based on the assembly of off-the-shelf and purpose-built components or services. The selection of software services from service repositories and their integration into software system architectures, but also the development of services for these repositories requires an accessible information infrastructure that allows the description and comparison of these services. General knowledge relating to software development is equally important in this context as knowledge concerning the application domain of the software. Both form two pillars on which the structural and behavioural properties of software services can be addressed. We investigate how this information space for software services can be organized. Focal point are ontologies that, in addition to the usual static view on knowledge, also intrinsically addresses the dynamics, i.e. the behaviour of software. We relate our discussion to the Web context, looking at the Web Services Framework and the Semantic Web as the knowledge representation framework

The State of Information and Communication Technology in Hungary – A Comparative Analysis

A novel comparative research and analysis method is proposed and applied on the Hungarian economic sectors. The question of what factors have an effect on their net income is essential for enterprises. First, the potential indicators related to economic sectors were studied and then compared to the net income of the surveyed enterprises. The data resulting from the comparison showed that the growing penetration of electronic marketpalces contributed to the change of the net income of enterprises in various economic sectors to the extent of 37%.
