Las relaciones bilaterales entre Argentina y Brasil : (1983-2014) : estrategias en el nuevo esquema global

Los procesos de integración regional que se han forjado en América del Sur a los largo de los últimos años, han permitido el establecimiento de lazos de cooperación entre los estados del Cono Sur. La vinculación entre Argentina y Brasil, si bien se ha caracterizado por una rivalidad y competencia geopolítica y económica, se ha afianzado como consecuencia de la interdependencia existente en materia comercial, de exportaciones e importaciones entre los países (PEREYRA DOVAL, 2014: 80). Las interacciones bilaterales, entre ambos países se fortalecen como parte de una base sólida de convivencia motivada por las cercanías geográficas. Esta proximidad promovió las relaciones de tipo comercial y económico, impulsando una cultura común.Fil: Corvalán, Facundo Gustavo . Universidad Nacional de Cuyo.

An interaction language for argumentation-based negotiation

Language is the medium used by heterogeneous and autonomous members of a community to communicate and to exchange knowledge. Social work allows members in a community to resolve problems that they could not face individually, but they must be able to interact in order to do it. Furthermore, is necessary to have a negotiation mechanism that allows members of a system to interact through it, trying to reach an agreement in order to satisfy their goals. Our work is oriented towards the design of an interaction language that allows argumentation-based negotiation among collaborative BDI agents.Eje: Inteligencia artificialRed de Universidades con Carreras en Informática (RedUNCI

Interaction among BDI argumentative agents: a dialogue games approach

Negotiation is a fundamental activity in a multi-agent system. The members of the system negotiate in order to coordinate their activities and to distribute resources and tasks trying to reach a state acceptable to all. Carrying out a negotiation process requires that agents be able to interact. In this work, protocol interaction is implemented by means of dialogues between agents, and the set of dialogues generated inside the same negotiation process conforms a conversation. We propose an interaction language that allows argumentation-based negotiation among collaborative BDI agents. For the language description we use a formalism, called Dialogue Games, which allows to specify the nature of the utterancesVI Workshop de Agentes y Sistemas Inteligentes (WASI)Red de Universidades con Carreras en Informática (RedUNCI

Specifying agent interaction protocols

Argumentation-based negotiation is an adequate alternative for modelling situations in which agents have limited information and bounded capacities. In this research line, each agent elaborates arguments as part of its own planning process and also to justify its proposals, counter-proposals and rejections during the negotiation process. Our proposal analyzes and compares three tools for the specification of interaction protocols: finite state machines, UML, and dialogues games.Eje: Inteligencia artificialRed de Universidades con Carreras en Informática (RedUNCI

Valiente, o la rebeldía amordazada

Este artículo reflexiona sobre la reproducción (y permanencia en el tiempo) de representaciones tradicionales en los contenidos de películas animadas orientadas a niños y a niñas de corta edad. Analizamos la más reciente producción de los estudios Disney, Valiente (2012), para arrojar luz sobre los modos de construcción de unos personajes que obtienen, a partir de sus prácticas y el manejo de sus sistemas de relaciones, premios y sanciones que tienden a reforzar aquello que históricamente ha sido socialmente legitimado. Concluimos que, al igual que la mayoría de las producciones animadas infantiles más consumidas, Valiente recupera un discurso tradicionalista y normativo que busca disimular a partir del uso de signos aparentes de ruptura y rebelión. La película manipula viejos y conocidos miedos infantiles, desalentando a las niñas que sientan el deseo de tomar la vida en sus propias manos para hacer con ella algo más próximo a su deseo que a las convenciones sociales impuestas.

An epistemic approach to model uncertainty in data-graphs

Graph databases are becoming widely successful as data models that allow to effectively represent and process complex relationships among various types of data. As with any other type of data repository, graph databases may suffer from errors and discrepancies with respect to the real-world data they intend to represent. In this work we explore the notion of probabilistic unclean graph databases, previously proposed for relational databases, in order to capture the idea that the observed (unclean) graph database is actually the noisy version of a clean one that correctly models the world but that we know partially. As the factors that may be involved in the observation can be many, e.g, all different types of clerical errors or unintended transformations of the data, we assume a probabilistic model that describes the distribution over all possible ways in which the clean (uncertain) database could have been polluted. Based on this model we define two computational problems: data cleaning and probabilistic query answering and study for both of them their corresponding complexity when considering that the transformation of the database can be caused by either removing (subset) or adding (superset) nodes and edges.Comment: 25 pages, 3 figure

On the complexity of finding set repairs for data-graphs

In the deeply interconnected world we live in, pieces of information link domains all around us. As graph databases embrace effectively relationships among data and allow processing and querying these connections efficiently, they are rapidly becoming a popular platform for storage that supports a wide range of domains and applications. As in the relational case, it is expected that data preserves a set of integrity constraints that define the semantic structure of the world it represents. When a database does not satisfy its integrity constraints, a possible approach is to search for a 'similar' database that does satisfy the constraints, also known as a repair. In this work, we study the problem of computing subset and superset repairs for graph databases with data values using a notion of consistency based on a set of Reg-GXPath expressions as integrity constraints. We show that for positive fragments of Reg-GXPath these problems admit a polynomial-time algorithm, while the full expressive power of the language renders them intractable.Comment: 35 pages , including Appendi

A Framework for Deliberation and Negotiation among BDI Agents

This work presents an interaction model among collaborative agents based on dialogues. For the specification we use a formalism, called Dialogue Games, which allows to describe the nature of the utterances available in each dialogue. We propose an interaction language which favors deliberation and argumentationbased negotiation among BDI agents. For each locution's specification we establish a set of preconditions, its meaning, the expected responses, and the modifications that it could produce. The interaction protocol and the interaction language as a whole can be used for specifying meaningful interaction between dialogical partners by following the rules of an individual dialogue.Facultad de Informátic
