Matchmaking Framework for B2B E-Marketplaces

In the recent years trading on the Internet become more popular. Online businesses gradually replace more and more from the conventional business. Much commercial information is exchanged on the internet, especially using the e-marketplaces. The demand and supply matching process becomes complex and difficult on last twenty years since the e-marketplaces play an important role in business management. Companies can achieve significant cost reduction by using e-marketplaces in their trade activities and by using matchmaking systems on finding the corresponding supply for their demand and vice versa. In the literature were proposed many approaches for matchmaking. In this paper we present a conceptual framework of matchmaking in B2B e-marketplaces environment.B2B Electronic Marketplaces, Conceptual Framework, Matchmaking, Multi- Objective Genetic Algorithm, Pareto Optimal

Semantic Matchmaking as Non-Monotonic Reasoning: A Description Logic Approach

Matchmaking arises when supply and demand meet in an electronic marketplace, or when agents search for a web service to perform some task, or even when recruiting agencies match curricula and job profiles. In such open environments, the objective of a matchmaking process is to discover best available offers to a given request. We address the problem of matchmaking from a knowledge representation perspective, with a formalization based on Description Logics. We devise Concept Abduction and Concept Contraction as non-monotonic inferences in Description Logics suitable for modeling matchmaking in a logical framework, and prove some related complexity results. We also present reasonable algorithms for semantic matchmaking based on the devised inferences, and prove that they obey to some commonsense properties. Finally, we report on the implementation of the proposed matchmaking framework, which has been used both as a mediator in e-marketplaces and for semantic web services discovery

From Sony to SOPA: The Technology-Content Divide

Copyright law, which is intended to provide creative rights and financial protection to content creators, has been challenged by technology innovators whose products have the potential to promote free speech, but could also be used to infringe on or facilitate infringement of existing copyright. From the invention of the printing press, technological innovations in communication have been accompanied by concerns for how the technology impacts copyright protections. The advent of the Internet and electronic devices spurred unprecedented accessibility and connectivity of information and ideas, while courts, regulators, and legal scholars in the United States sought to clarify how copyright law applied to these technologies. This case reviews the recent history of copyright law and explores the conflict between three stakeholders in intellectual property law: copyright holders, technology producers, and legislative enforcers. Beginning with the decision of Sony v. Universal Studios (known colloquially as the “Betamax case”) in 1984 and culminating with the Stop Online Piracy Act (SOPA) in 2011, the legal precedents for intellectual property have yet to mutually satisfy copyright holders and technology producers. Addressing the Digital Millenium Copyright Act as well as peer-to-peer, torrenting, and other file sharing platforms, this case provides an overview of the touchstone technology and the verdicts associated with these products. This background note prepares students to analyze the 2011 SOPA legislation and discuss its repercussions for copyright law and technological innovation. During class discussions, students analyze the SOPA legislation and articulate their opinions on how it would impact various stakeholder groups. Students then work in groups to amend the legislation with the goal of creating a bill more likely to be signed into law

From fuzzy to annotated semantic web languages

The aim of this chapter is to present a detailed, selfcontained and comprehensive account of the state of the art in representing and reasoning with fuzzy knowledge in Semantic Web Languages such as triple languages RDF/RDFS, conceptual languages of the OWL 2 family and rule languages. We further show how one may generalise them to so-called annotation domains, that cover also e.g. temporal and provenance extensions

Semantic Inference on Heterogeneous E-Marketplace Activities

An electronic marketplace (e-marketplace) is a common business information space populated with many entities of different system types. Each of them has its own context of how to process activities. This leads to heterogeneous e-marketplace activities, which are difficult to make interoperable and inferred from one entity to another. This study solves this problem by proposing a concept of separation strategy and implementing it through providing a semantic inference engine with a novel inference algorithm. The solution, called the RuleXPM approach, enables one to semantically infer a next e-marketplace activity across multiple contexts/domains. Experiments show that the cross-context/cross-domain semantic inference is achievable. This paper is an understanding of many aspects related to heterogeneous activity inference

Opérationnaliser les compétences transversales en analyse bibliométrique et en visualisation des réseaux au thème de l’économie collaborative

Une analyse bibliométrique utilisant la visualisation de réseaux pour représenter le thème de l’Économie collaborative (ÉC) au sein de la recherche scientifique a été réalisée dans le cadre de ce mémoire. Pour ce faire, 729 documents ont été recensés sur deux bases de données (Scopus et Web of Science). Ces documents ont été désambiguïsés, nettoyés et standardisés pour être compilés et analysés avec BibExcel et VOSviewer. Différentes statistiques bibliométriques et analyses non évaluatives (cooccurence, cocitation, coauteur) ont pu être exécutées et visualisées afin de mieux comprendre le milieu de l’ÉC. Les résultats de cette recherche sont multiples. D’une part, l’importance des États-Unis est notoire, autant au niveau des auteurs, des organisations que des collaborations. Ensuite, différentes grappes thématiques ont pu être formées selon la variable étudiée. L’importance de la technologie, du tourisme, du développement durable, de l’aspect managérial et enfin de la théorie/conceptualisation de l’ÉC est récurrente. Plusieurs auteurs sont déterminants dans la littérature, mais les plus influents sont Russel Belk et Rachel Botsman. Le livre What’s yours is mine (Botsman et Rogers, 2010) est le document le plus cité, et ce malgré le fait qu’il soit écrit par des auteurs ne provenant pas du milieu académique. Les relations entre les publications étudiées démontrent une cohésion entre les différentes idées et thématiques véhiculées dans le domaine, et ce malgré le fait qu’il existe des problèmes définitionnels et conceptuels à propos de l’ÉC. Enfin, l’évolution chronologique des publications subit une croissance très importante depuis 2016 et témoigne d’un champ de recherche émergent : le développement durable. La somme des résultats analysés donne un nouveau regard sur l’ÉC. Elle permet pour les nouveaux chercheurs de les introduire aux caractéristiques du domaine et sert aux experts à cerner les thématiques, revues et auteurs à considérer lors de leurs propres analyses. La méthodologie et les résultats de cette recherche furent publiés dans le Journal of Cleaner Production (Ertz & Leblanc-Proulx, 2018), le Journal of Markteing Analytics (Ertz & Leblanc-Proulx, 2019a) et le livre Sage Research methods Cases (Ertz & Leblanc-Proulx, 2019b)

The Sharing Economy in Europe: Developments, Practices, and Contradictions

This open access book considers the development of the sharing and collaborative economy with a European focus, mapping across economic sectors, and country-specific case studies. It looks at the roles the sharing economy plays in sharing and redistribution of goods and services across the population in order to maximise their functionality, monetary exchange, and other aspects important to societies. It also looks at the place of the sharing economy among various policies and how the contexts of public policies, legislation, digital platforms, and other infrastructure interrelate with the development and function of the sharing economy. The book will help in understanding the future (sharing) economy models as well as to contribute in solving questions of better access to resources and sustainable innovation in the context of degrowth and growing inequalities within and between societies. It will also provide a useful source for solutions to the big challenges of our times such as climate change, the loss of biodiversity, and recently the coronavirus disease pandemic (COVID-19). This book will be of interest to academics and students in economics and business, organisational studies, sociology, media and communication and computer science
