abstract = {Technological advances, especially in the field of artificial intelligence, raise subjects related to the behaviour of autonomous systems. The ability to judge how far some behaviour is ethically correct is inherent to humans, and one of the great challenges is to replicate such ability in artificial systems. Engineering, aware that human values must be considered in the decision-making process, is currently focused on developing mechanisms to embed these values into autonomous systems. This article proposes a decision model that enables autonomous intelligent agents to select actions that are aligned with their value system. It considers not only the relevance that different values have for an agent, and how much an action promotes a certain value, but also models in a rigorous manner the interaction of different values within a value system. An instantiation of the model is put forward, based on Schwartz's basic values theory, non-additive fuzzy measures, and the discrete Choquet integral. Then the performance of the approach is illustrated by determining the value alignment of different decisions using the well-known iterated prisoner's dilemma.},

abstract = {Nowadays, Artificial Intelligence faces a significant challenge in implementing ethical behaviour in autonomous agents. The development of technologies that consider human values in the decision-making process of such agents is crucial. While this feature should be included in the agent's design objectives, the primary goal is to build value-aware agents that act appropriately in changing environments. This requires the creation of mechanisms that support the agent's own value system. This paper presents a model of an agent that makes decisions based on its value system and a value promotion scheme for available actions. The model uses a fuzzy measure to represent the value system, and aggregation operators to determine the action that best aligns with the agent's preferences. Schwartz's basic value theory and Choquet's discrete integral are used as an example of model implementation. Finally, the model is illustrated by determining the value alignment of different decisions in a simplified tax-paying context.},

abstract = {In the last years, many novel applications have appeared that promote the provision of services or activities in a collaborative way. Examples of such proposals are collaborative transportation services (uber, glovo, amazon flex, etc.), crowdsourcing, exchange help services among citizens, and others. The intrinsic idea behind such systems is to take advantage of existing ``capacities'' for providing new services or incrementing the efficiency of daily tasks of people at a low cost. Also, many researchers have focused and are analysing novel ideas and approaches in this direction. The concept of Smart Cities is a clear representation of this hype and provides a playground for novel approaches where the aim is to provide a high level of services to citizens in an optimized and thus, more efficient way. As a result of this research effort, many proposals have been and are suggested that could be deployed in the real world. However, such proposals also bring up multiple non-technical issues that need to be tackled before they can be actually implemented in practice. In this sense, in this paper we analyse legal implications of a proposal for collaborative service provision. In particular, we analyse the legal issues related to a recent work on taxi assignments with compensation from the standpoint of the Spanish legislation. From this exercise, we extract a set of topics and requirements, which need to be addressed so as to pave the way for the potential real-world deployment of such a system in a future.},
