Shopbots: A Syntactic Present, A Semantic Future

Despite high expectations, shopbots have yet to significantly facilitate a richer, more satisfying online shopping experience for users. By taking advantage of Semantic Web and Web services technologies, however, researchers can overcome current technological limitations and finally realize the shopbot's significant potential. © 2006 IEEE

Design options for subscription managers

An important issue in open agent systems such as the Internet is the discovery of service providers by potential consumers (requesters). This paper is concerned with services that involve the ongoing provision of up-to-date information to requesters. We explore three separate issues: subscription to an information provider for ongoing provision of information; monitoring for new information providers; and maintaining awareness of when providers disappear from the system. We explore several models for how this functionality may best be provided, with emphasis on the ways in which certain choices affect the overall system; and provide an analysis of preferred design options for environments with different characteristics

Automated Servicing of Agents

Agents need to be able to adapt to changes in their environment. One way to achieve this, is to service agents when needed. A separate servicing facility, a multi-agent factory, is capable of automatically modifying agents. This paper discusses th

Models of Interaction as a Grounding for Peer to Peer Knowledge Sharing

Most current attempts to achieve reliable knowledge sharing on a large scale have relied on pre-engineering of content and supply services. This, like traditional knowledge engineering, does not by itself scale to large, open, peer to peer systems because the cost of being precise about the absolute semantics of services and their knowledge rises rapidly as more services participate. We describe how to break out of this deadlock by focusing on semantics related to interaction and using this to avoid dependency on a priori semantic agreement; instead making semantic commitments incrementally at run time. Our method is based on interaction models that are mobile in the sense that they may be transferred to other components, this being a mechanism for service composition and for coalition formation. By shifting the emphasis to interaction (the details of which may be hidden from users) we can obtain knowledge sharing of sufficient quality for sustainable communities of practice without the barrier of complex meta-data provision prior to community formation

The Information Flow Problem in multi-agent systems

[EN] One of the problems related to the multi-agent systems area is the adequate exchange of information within the system. This problem is not only related to the availability of highly efficient and sophisticated message-passing mechanisms, which are in fact provided with by current multi-agent platforms, but also to the election of an appropriate communication strategy, which may also greatly influence the ability of the system to cope with the exchange of large amounts of data. Ideally, the communication strategy should be compatible with how the information flows in the system, that is, how agents share their knowledge with each other in order to fulfill the system-level goals. In this way, MAS designers must deal with the problem of analyzing the multi-agent system with respect the communication strategy that best suits the way the information flows in that particular system. This paper presents a formalization of this problem, which has been coined as the Information Flow Problem, and also presents a complete case study with an empirical evaluation involving four well-known communication strategies and eight typical multi-agent systems.This work was partially supported by MINECO/FEDER TIN2015-65515-C4-1-R and TIN2014-55206-R of the Spanish government.Búrdalo Rapa, LA.; Terrasa Barrena, AM.; Julian Inglada, VJ.; García-Fornes, A.

Agentes inteligentes para propiciar la accesibilidad web

A catorce años de las primeras recomendaciones de la W3C, los enfoques que asisten a la accesibilidad de productos Web siguen requiriendo de la intervención y el juicio humano. Si bien existen buenas propuestas que aplican técnicas inteligentes al proceso de evaluación y reparación, la brecha entre el soporte existente y las necesidades reales de automatización para detectar y reparar con mayor precisión las barreras de Accesibilidad, es aún muy significativa. En este trabajo se realiza un profundo relevamiento de los enfoques que dan soporte a la accesibilidad Web exhibiendo rasgos inteligentes. A tal fin, se propone un Framework de Evaluación donde se analizan las características de los enfoques para determinar sus fortalezas y debilidades. También y como parte de este trabajo, se propone una Taxonomía de Agentes para asistir al proceso de revisión en la identificación y comprensión de los agentes inteligentes.WIS - X Workshop ingeniería de softwareRed de Universidades con Carreras en Informática (RedUNCI

Agents in decentralised information ecosystems: the DIET approach

The complexity of the current global information infrastructure requires novel means of understanding and exploiting the dynamics of information. One means may be through the concept of an information ecosystem. An information ecosystem is analo gous to a natural ecosystem in which there are flo ws of materials and energy analo gous to information flow between many interacting individuals. This paper describes a multi-agent platform, DIET (Decentralised Information Ecosystem Technologies) that can be used to implement open, robust, adaptive and scalable ecosystem-inspired systems. We describe the design principles of the DIET software architecture, and present a simple example application based upon it. We go on to consider how the DIET system can be used to develop information brokering agents, and how these can contribute to the implementation of economic interactions between agents, as well as identifying some open questions relating to research in these areas. In this way we show the capacity of the DIET system to support applications using information agents.Future and Emerging Technologies arm of the IST Programme of the European Union, under the FET Proactive Initiative – Universal Information Ecosystems (FET, 1999), through project DIET (IST -1999-10088), BTexaCT Intelligent Systems Laboratory for stimulating discussion and comment
