    Assistive Technologies (AT) are an application area where several Artificial Intelligence techniques and tools have been successfully applied to support elder or impeded people on their daily activities. However, approaches to AT tend to center in the user-tool interaction, neglecting the user's connection with its social environment (such as care-takers, relatives and health professionals) and the possibility to monitor undesired behaviour providing both adaptation to a dynamic environment and early response to potentially dangerous situations. In previous work we have presented Coaalas, an intelligent social and norm-aware device for elder people that is able to autonomously organize, reorganize and interact with the dierent actors involved in elder-care, either human actors or other devices. In this paper we put our work into context, by first examining what are the desirable properties of such a system, analysing the state of the art on the relevant topics, and verifying the validity of our proposal.

    Artificial Intelligence techniques and tools have been applied to Assis- tive Technologies (AT) in order to support elder or impeded people on their daily activities. A common application are intelligent pill dispensers and reminders that help the patient comply with his medication. This has become even more important, as patients suffering from multiple pathologies are prescribed cocktails of drugs that require strict compliance in order to achieve a successful treatment. Existing intelligent pill dispensers tend to focus in the user-tool interaction, neglecting user¿s connection with its social environment and the possibility to monitor patient¿s behaviour, effectively adapting to a dynamic environment and providing early re- sponse to potentially dangerous situations by detecting unexpected or undesired patterns of behaviour. In previous work we have presented COAALAS, an intelligent social and norm-aware device for elder people that is able to autonomously organize, reorganize and interact with the different actors involved in elder-care, either human actors or other devices. In this paper, we present SPiDer an intelligent pill dispenser integrated with the COAALAS architecture.

    In agent research, emergent narrative aims for practical solutions to the narrative paradox problem in both drama and interactive scenarios. At the same time, organisational frameworks can be used in games to provide flexibility, adaptiveness, or social-awareness. In this paper, we propose an extension of our cOncienS framework to support emergent narrative in games with two objectives: 1) provide social-awareness in emergent narrative by means of an organisational model, and 2) create convincing dynamic and flexible storytelling in games.

    Non-compliance with prescribed medication is a major problem for elder people living alone in developed countries. Forgetfulness and confusion can lead to it, specially when multiple pathologies require a cocktail of diff erent medications each delivered at different time intervals during di fferent periods of time. Assistive technologies, a recent application area for a wide range of Arti cial Intelligence techniques and tools, have been e ectively used for supporting people in their daily activities. This paper introduces the design and implementation of a system for assisting elder people on following the treatment prescribed by a professional, with the novelty of being based in social and organisational aware assistive technology.

    Assistive technologies are applied to support people in their daily life. Most approaches focus solely on the direct interaction between users – in our case, disabled patients - and the assistive tool, but Artificial Intelligence (AI) has the potential to provide innovative mechanisms and methods capable of taking into account more complex interactions. For instance, such an approach can take into account the important role that third parties may have in user activities, and explicitly reflect the social constraints that apply in the relationship between device and patient. In COAALAS (COmpanion for Ambient Assisted Living on Alive-ShareIt platforms), organizational and normative structures are used to model the sensor network around disabled users as societies, along with the expected behavioural patterns, effectively supporting smart assistive tools that integrate in perfect harmony with the humans around them. The result is an assistive society of ambient-aware assistive tools.

    The implementation of AI in commercial games is usually based on low level designs that makes the control predictable, unadaptive, and non reusable. Recent algorithms such as HTN or GOAP prove that higher levels of abstraction can be applied for better performance. We propose that approaches based on Organizational Theory can help providing a sound alternative for these implementations. In this paper we present CONCIENS, an integration of the ALIVE organizational framework into commercial games. We introduce a proof-of-concept implementation based on the integration to Warcraft III.

    The AI techniques used in commercial games are usually predictable, inflexible and unadaptive, causing a lack of realism for the player. In this paper, we introduce a proposal of integrating the ALIVE framework, based on Organisational theory, into commercial games. The objective of our proposal is to provide game AI developers with a methodology and tools to model gaming scenarios using social structures.

    Extension-based argumentation semantics have shown to be a suitable approach for performing practical reasoning. Since extension-based argumentation semantics were formalized in terms of relationships between atomic arguments, it has been shown that extension-based argumentation semantics based on admissible sets such as stable semantics can be characterized in terms of answer sets. In this paper, we present an approach for characterizing SCC-recursive semantics in terms of answer set models. In particular, we will show a characterization of CF2 in terms of answer set models. This result suggests that not only extension-based argumentation semantics based on admissible sets can be characterized in terms of answer sets; but also extension-based argumentation semantics based on Strongly Connected Components can be characterized in terms of answer sets.

    Assistive technologies represent a recent application area of a wide variety of Arti cial Intelligence methods and tools to support people in their activities of daily living. But most approaches do only center in the direct interaction between the user and the assistive tool, without taking into consideration the important role that other actors (caregivers, relatives) may have in the user activities, nor they explicitly re ect the norms and regulations that apply in such scenarios. In this paper we present an approach to the development of assistive technologies which uses organisational and normative elements to ease the design of both the social network arround the user and their expected behavioural patterns.

    This paper presents an agent-based methodological approach to design distributed service-oriented systems which can adapt their behaviour according to changes in the environment and in the user needs, even taking the initiative to make suggestions and proactive choices. The highly dynamic, regulated, complex nature of the distributed, interconnected services is tackled through a methodological framework composed of three interconnected levels. The framework relies on coordination and organisational techniques, as well as on semantically annotated Web services to design, deploy and maintain a distributed system, using both a top-down and bottom-up approach. We present results based on a real use case: interactive community displays with tourist information and services, dynamically personalised according to user context and preferences.

    Extension-based argumentation semantics have been shown to be a suitable approach for performing practical reasoning. Since extension-based argumentation semantics were formalized in terms of relationships between atomic arguments, it has been shown that extension-based argumentation semantics (such as the grounded semantics and stable semantics) can be characterized by logic programming semantics with negation as failure. Recently, it has been shown that argumentation semantics such as the preferred semantics and the CF2 semantics can be characterized in terms of logic programming semantics. In this paper, we make a short overview w.r.t. recent results in the close relationship between extension-based semantics and logic programming semantics with negation as failure. We also show that there is enough evidence to believe that the use of declarative approaches based on logic programming semantics with negation as failure is a practical approach for performing practical reasoning following an argumentation reasoning approach.

    Interconnected service providers constitute a highly dynamic, complex, distributed environment. Multi-agent system design-methodologies have been try-ing to address this kind of environments for a long time. The European project ALIVE presents a framework of three interconnected levels that tackles this issue relying on organisation and coordination techniques, as well as on developments in the Web-services world. This paper presents initial results focused on a high-tech, real use case: interactive community displays with touristic information and services, dynamically personalized according to user preferences and local laws.
