Intelligent negotiation model for ubiquitous group decision scenarios
Supporting group decision-making in ubiquitous contexts is a complex task that must deal with a large amount of
factors to succeed. Here we propose an approach for an intelligent negotiation model to support the group decision-making process
specially designed for ubiquitous contexts. Our approach can be used by researchers that intend to include arguments, complex
algorithms and agents' modelling in a negotiation model. It uses a social networking logic due to the type of communication
employed by the agents and it intends to support the ubiquitous group decision-making process in a similar way to the real process,
which simultaneously preserves the amount and quality of intelligence generated in face-to-face meetings. We propose a new look
into this problematic by considering and defining strategies to deal with important points such as the type of attributes in the multicriteria
problems, agents' reasoning and intelligent dialogues.This work has been

A Role-Based Approach for Orchestrating Emergent Configurations in the Internet of Things
The Internet of Things (IoT) is envisioned as a global network of connected
things enabling ubiquitous machine-to-machine (M2M) communication. With
estimations of billions of sensors and devices to be connected in the coming
years, the IoT has been advocated as having a great potential to impact the way
we live, but also how we work. However, the connectivity aspect in itself only
accounts for the underlying M2M infrastructure. In order to properly support
engineering IoT systems and applications, it is key to orchestrate
heterogeneous 'things' in a seamless, adaptive and dynamic manner, such that
the system can exhibit a goal-directed behaviour and take appropriate actions.
Yet, this form of interaction between things needs to take a user-centric
approach and by no means elude the users' requirements. To this end,
contextualisation is an important feature of the system, allowing it to infer
user activities and prompt the user with relevant information and interactions
even in the absence of intentional commands. In this work we propose a
role-based model for emergent configurations of connected systems as a means to
model, manage, and reason about IoT systems including the user's interaction
with them. We put a special focus on integrating the user perspective in order
to guide the emergent configurations such that systems goals are aligned with
the users' intentions. We discuss related scientific and technical challenges
and provide several uses cases outlining the concept of emergent
configurations.Comment: In Proceedings of the Second International Workshop on the Internet

Defining an architecture for a ubiquitous group decision support system
Supporting group decision-making in ubiquitous contexts is fundamental
while developing Group Decision Support Systems (GDSS). Here we propose
an architecture that assures ubiquity and allows the development of a system
which can be used anywhere at any time and through almost any sort of electronic
device. Our approach can be used by developers that intend to build Ubiquitous
Group Decision Support Systems (UbiGDSS). It uses three main components that
are interconnected and that will allow to collect and preserve the amount and
quality of intelligence generated in face-to-face meetings.This work was supported by COMPETE Programme (operational programme for

Urban management revolution: intelligent management systems for ubiquitous cities
A successful urban management support system requires an integrated approach. This integration includes bringing together economic, socio-cultural and urban development with a well orchestrated transparent and open decision making mechanism. The paper emphasises the importance of integrated urban management to better tackle the climate change, and to achieve sustainable urban development and sound urban growth management. This paper introduces recent approaches on urban management systems, such as intelligent urban management systems, that are suitable for ubiquitous cities. The paper discusses the essential role of online collaborative decision making in urban and infrastructure planning, development and management, and advocates transparent, fully democratic and participatory mechanisms for an effective urban management system that is particularly suitable for ubiquitous cities. This paper also sheds light on some of the unclear processes of urban management of ubiquitous cities and online collaborative decision making, and reveals the key benefits of integrated and participatory mechanisms in successfully constructing sustainable ubiquitous cities
Including credibility and expertise in group decision-making process: an approach designed for UbiGDSS
Supporting group decision-making when the decision-makers are
spread around the world is a complex process. The mechanisms of automated
negotiation, such as argumentation, can be used in Ubiquitous Group Decision
Support Systems to help decision-makers find a solution based on their preferences.
However, there are some other important issues that affect the decisionmaking
process beyond typical preferences over criteria and alternatives. In this
paper, we propose an algorithm that will allow agents to reason about self-expertise
and other decision makers’ credibility. This way, we intend agents to achieve
better quality and more consensual decisions. Our algorithm includes not only
the decision-maker’s preferences but also his intentions in the process. By using
the proposed model, agents achieved a stronger consensus in all scenarios that
were considered and higher satisfaction levels in the most complex scenarios.This work was supported by COMPETE Programme (operational programme for competitiveness)

A User-Focused Reference Model for Wireless Systems Beyond 3G
This whitepaper describes a proposal from Working Group 1, the Human Perspective of the Wireless World, for a user-focused reference model for systems beyond 3G. The general structure of the proposed model involves two "planes": the Value Plane and the Capability Plane. The characteristics of these planes are discussed in detail and an example application of the model to a specific scenario for the wireless world is provided
