A Model of Collaborating Agents for Content-Based Electronic Document Filtering
- Papaspyrou Sgouropoulou And; N. S. Papaspyrou; C. E. Sgouropoulou; E. S. Skordalakis
. The huge volume of distributed information that is nowadays available in electronic multimedia documents forces a lot of people to consume a significant percentage of their time looking for documents that contain information useful to them. The filtering of electronic documents seems hard to automate, partly because of document heterogeneity, but mainly because it is difficult to train computers to have an understanding of the contents of these documents and make decisions based on user-subjective criteria. In this paper, we suggest a model for the automation of content-based electronic document filtering, supporting multimedia documents in a wide variety of...

Designing and Implementing Electronic Auctions in a Multiagent System Environment
- Davide Roggero; Fioravante Patrone; Viviana Mascardi
Agent-Mediated Electronic Commerce is gaining a wide consensus both from the academia and from the industry, since it provides the right abstractions, models and tools to face the challenges that electronic commerce raises. According to C.Sierra, e-commerce can be described as organization + mechanism + trust, where mechanism is concerned with the rules that govern the interaction among agents in such a way that certain properties can be guaranteed.

Reducing Buyer Search Costs: Implications for Electronic Marketplaces
- Yannis Bakos Stern
Information systems can serve as intermediaries between the buyers and the sellers in a market, creating an "electronic marketplace" that lowers the buyers' cost to acquire information about seller prices and product offerings. As a result, electronic marketplaces reduce the inefficiencies caused by buyer search costs, in the process reducing the ability of sellers to extract monopolistic profits while increasing the ability of markets to optimally allocate productive resources. This article models the role of buyer search costs in markets with differentiated product offerings. The impact of reducing these search costs is analyzed in the context of an electronic marketplace,...

Towards Regulating Electronic Communities
We present work-in-progress towards a high-level e-commerce architecture for the electronic
marketplace. We separate out the main components responsible for trading based on contractual
relationships and trusted service delivery. In this setting, we view an enterprise as an autonomous
entity that interacts with others according to their private utility function and a set of shared goals
expressed as normative statements contained within contracts. The Governance component provides a
regulated environment where the citizen's behaviour can be monitored and compared against agreed
contracts. Regulatory mechanisms can be deployed by the Governance to maintain contractual
integrity of transactions.

An Open Electronic Marketplace through Agent-based Workflows: MOPPET
- Sena Arpinar; Asuman Dogac; Nesime Tatbul
We propose an electronic marketplace architecture, called MOPPET, where the commerce processes in the marketplace are modeled as adaptable agent-based workflows. The higher level of abstraction provided by the workflow technology makes the customization of electronic commerce processes for different users possible. Agent-based implementation, on the other hand, provides for a highly reusable component-based workflow architecture as well as negotiation ability and the capability to adapt to dynamic changes in the environment. Agent communication is handled through Knowledge Query and Manipulation Language (KQML). A workflow-based architecture also makes it possible for complete modeling of electronic commerce processes by allowing involved...

Electronic Tendering : Is it delivering? a UK and European perspective
- Tony Westcott; Peter Mayer
This paper examines the extent to which electronic tendering is delivering promised business efficiencies for the construction industry. It reviews the impact of European Union and UK government policy, compares key UK and German market factors influencing the use of e-tendering – the relative use, opportunities and motivating factors, examines the extent of its use and reasons for the reluctance to commit to fully electronic tendering, including the issues of security, certainty and speed of delivery and receipt, compatibility, document integrity and confidentiality, and reviews the increasing use of project webs and internet-based tender information services.

Modelo de negociación automática bilateral para entornos abiertos de comercio electrónico
- López, Miguel Ángel; Velasco Pérez, Juan Ramón; Marsá Maestre, Iván; Navarro, Andrés
Este artículo presenta un modelo para la negociación automática bilateral y multiparámetrica en entornos abiertos de
comercio electrónico. El modelo se describe en el ámbito de un entorno competitivo de agentes software, en el que uno
de los agentes del sistema actúa como comprador y otro de los agentes como vendedor. En un sistema abierto, la
incertidumbre acerca del comportamiento de otro agente es clave, correspondiéndose con la realidad presente en medios
convencionales de negociación o en comercio electrónico e Internet. Aún así, la actitud de un agente en un entorno
competitivo frente a otro agente, puede diferir en cuanto al nivel de confianza recíproca...

The Intelligent Pen-Toward a Uniform Treatment of Electronic Documents
- Marcel Götze; Stefan Schlechtweg; Thomas Strothotte
This paper introduces the intelligent pen metaphor, an approach to uniformly treat interaction with electronic documents, especially for marking and annotating a document. This enables an easier handling of electronic documents also for novice and inexperienced users. Interaction tasks are combined in one metaphor that is well known to the user from his or her daily work with paper documents. We also present a prototypical implementation that exploits an alternative user interface to offer additional support for these users. All information added to the document by a user is stored together with the original text allowing an easy document exchange...

Non-Repudiation in An Agent-Based Electronic Commerce System
- Chin Chuan Liew; Wee Keong Ng; Ee Peng Lim; Beng Suang Tan; Kok Leong Ong; C. -c. Liew; W. -k. Ng; E. -p. Lim; B. -s. Tan; K. -l. Ong
Abecos is an agent-based e-commerce system under development at the Nanyang Technological University. It aims to provide a software infrastructure for a large scale, distributed system whereby seller and buyer (software) agents engage in e-commerce activities on behalf of organizations and individuals. A key factor in making this system usable in practice is strict security controls. One aspect of security is the provision of non-repudiation services. As protocols for non-repudiation have focused on the singlemessage non-repudiation, its adaptation to afford non-repudiation in a communication session for two agents in Abecos is inefficient. In this work, we investigate and propose a...

Receipt-Free Electronic Voting Scheme with a Tamper-Resistant Randomizer
- Byoungcheon Lee; Kwangjo Kim
We investigate the receipt-freeness issue of electronic voting protocols. Receipt-freeness means that a voter neither obtains nor is able to construct a receipt proving the content of his vote. [Hirt01] proposed a receipt-free voting scheme by introducing a third-party randomizer and by using divertible zero-knowledge proof of validity and designatedverifier re-encryption proof. This scheme satisfies receipt-freeness under the assumption that the randomizer does not collude with a buyer and two-way untappable channel exists between voters and the randomizer. But
