Semantic discovery and reuse of business process patterns

Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse

On the emergent Semantic Web and overlooked issues

The emergent Semantic Web, despite being in its infancy, has already received a lotof attention from academia and industry. This resulted in an abundance of prototype systems and discussion most of which are centred around the underlying infrastructure. However, when we critically review the work done to date we realise that there is little discussion with respect to the vision of the Semantic Web. In particular, there is an observed dearth of discussion on how to deliver knowledge sharing in an environment such as the Semantic Web in effective and efficient manners. There are a lot of overlooked issues, associated with agents and trust to hidden assumptions made with respect to knowledge representation and robust reasoning in a distributed environment. These issues could potentially hinder further development if not considered at the early stages of designing Semantic Web systems. In this perspectives paper, we aim to help engineers and practitioners of the Semantic Web by raising awareness of these issues

SOLACE: A framework for electronic negotiations

Copyright @ 2011 Walter de Gruyter GmbHMost existing frameworks for electronic negotiations today are tied to specific negotiation systems for which they were developed, preventing them from being applied to other negotiation scenarios. Thus, the evaluation of electronic negotiation systems is difficult as each one is based on a different framework. Additionally, each developer has to design a new framework for any system to be developed, leading to a ‘reinvention of the wheel’. This paper presents SOLACE—a generic framework for multi-issue negotiations, which can be applied to a variety of negotiation scenarios. In contrast with other frameworks for electronic negotiations, SOLACE supports hybrid systems in which the negotiation participants can be humans, agents or a combination of the two. By recognizing the importance of strategies in negotiations and incorporating a time attribute in negotiation proposals, SOLACE enhances existing approaches and provides a foundation for the flexible electronic negotiation systems of the future

The theory of the lemon markets in IS research

The “lemon” problem was initially posed by Nobel Prize winner Akerlof in his seminal article of 1970 and showed how a market with unbalanced information, called information asymmetry, can lead to complete disappearance or to offerings with poor quality where bad products (lemons) wipe out the good ones. Empirical evidence for Akerlof’s theory came originally from the market of used cars, where the lemon is a well known problem. However the theoretical model of the “lemon” problem has proven also to be valid on other markets and in comparable situations like internal markets. The theory is also been used more and more in IS research especially since the emerging e-commerce initiatives and the continuous growth of e-markets and auctions. In this chapter we bring a description of the theory by presenting its nomological network and its linkages to other well known theories in IS research. The relevance for the theory is shown to explain phenomenon’s in the IS discipline. An overview is given of current and past IS articles using the Lemon Market theory (LMT) together with a bibliographical analysis of the references to the original Akerlof article

An Efficient and Decentralized Blockchain-based Commercial Alternative (Full Version)

While online interactions and exchanges have grown exponentially over the past decade, most commercial infrastructures still operate through centralized protocols, and their success essentially depends on trust between different economic actors. Digital advances such as blockchain technology has led to a massive wave of \textit{Decentralized Ledger Technology} (\textit{DLT}) initiatives, protocols and solutions. This advance makes it possible to implement trustless systems in the real world, which, combined with appropriate economic and participatory incentives, would foster the proper functioning and drive the adoption of a decentralized platform among different actors. This paper describes an alternative to current commercial structures and networks by introducing \textit{Lyzis Labs}, which is is an incentive-driven and democratic protocol designed to support a decentralized online marketplace, based on blockchain technology. The proposal, \textit{Lyzis Marketplace}, allows to connect two or more people in a decentralized and secure way without having to rely on a \textit{Trusted Third Party} (\textit{TTP}) in order to perform physical asset exchanges while mainly providing transparent and fully protected data storage. This approach can potentially lead to the creation of a permissionless, efficient, secure and transparent business environment where each user can gain purchasing and decision-making power by supporting the collective welfare while following their personal interests during their various interactions on the network.Comment: 62 pages, 9 figures, 19 table

Information richness and trust in V-commerce: implications for services marketing

Purpose: The potential for e-commerce is limited by a trust deficit when traders do not interact in a physical, bricks-and-mortar context. The theory of information richness posits that equivocal interactions, such as ones requiring trust, can be facilitated through communication media that transmit multiple cues interactively. We examine the potential of information-rich virtual worlds to reduce this trust deficit compared with more traditional web-based e-tailing environments. Design/Methodology: Rather than focusing on stated intentions we adopt an experimental approach to measure behaviour. Participants receive performance-related financial incentives to perform trust games in different information-rich treatments that represent three retail environments: a physical environment representing bricks-and-mortar trade, an electronic environment representing web-based online retailing and a virtual environment representing virtual world retail. Findings: We find that the two dimensions of trust significantly differ between the treatments. In particular, as hypothesised, both trustingness and trustworthiness are higher in the virtual than in the electronic environment. However, contrary to our hypotheses, physical trade is not associated with greater trust than virtual trade. Implications: We extend previous research by demonstrating how the information richness of the virtual world interface can promote e-commerce by deepening trust between trading partners. Our research also complements existing work that approaches product and service interfaces through the lens of servicescapes. The findings also contribute towards the development of services marketing practice and the design of e-commerce environments
