Texto completoMulti-agent systems have been used in a wide range of applications from computer-based simulations and mobile robots to agent-oriented programming and intelligent systems in real environments. However, the largest environment in which software agents can interact is, without any doubt, the World Wide Web and ever since its birth agents have been used in various applications such as search engines, e-commerce, and most recently the semantic web. However, agents have yet to be used on the Web in a way that leverages the full power of artificial intelligence and multi-agent systems, which have the potential of making life much easier for humans. This thesis investigates how this can be changed, and how agents can be brought to the core of the online experience in the sense that we want people to talk and interact with agents instead of "just using yet another application or website". We analyze what makes it hard to develop intelligent agents on the web and we propose a web agent model (WAM) inspired by recent results in multi-agent systems. Nowadays, a simple conceptual model is the key for widespread adoption of new technologies and this is why we have chosen the MASQ meta-model as the basis for our approach, which provides the best compromise in terms of simplicity of concepts, generality and applicability to the web. Since until now the model was introduced only in an informal way, we also provide a clear formalization of the MASQ meta-model.Next, we identify the three main challenges that need to be addressed when building web agents: integration of bodies, web semantics and user friendliness. We focus our attention on the first two and we propose a set of principles to guide the development of what we call strong web agents. Finally, we validate our proposal through the implementation of an award winning platform called Kleenk. Our work is just a step towards fulfilling the vision of having intelligent web agents mediate the interaction with the increasingly complex World Wide Web

Texto completoA user interface architecture model provides a structure for interactive software in order to ease the design of friendly user interfaces, their automatic production and to take in to account standard components. These objectives haven't been satisfied yet despite the numerous models proposed. In this thesis we have studied the main aspects related to the interactive software production and its architecture. They concern both interaction models, styles and development tools. We distinguish two main classes of architecture models : the centralized ones and the multi-agents (distributed) ones. We propose the multi-agents model called AMF (Agent Multi-Facettes) in order to provide for the developer a software structure which : give the same importance to all aspects of dialog (interaction, multiple presentation, constraints handling, help and errors handling, capturing user behavior) ; bring more detailed decomposition of interactive agents ; define concepts and methods for communication between the interactive software components in order to ease an extension of the agents by new functions or services ; ease the elaboration of interactive software by automatisation ; and ease the elaboration of development tools. Concerning development tools, we consider those specialized environments are ease-to-use by designers and users of the application domain. So, we propose a software framework which constitutes a reference model for specialized environments in different domains. This framework integrates a set of basic and generic tools allowing the elaboration, the execution and the evaluation of the AMF user interface. Its architecture is also based on AMF model and tools integration is made by using a base of specializable AMF agents. Finally in order to apply our propositions, we conceveid and implemented an environment called E4 (in french Environment d'Etudes Ergonomiques d'Ecrans) specialized in development of in-car interfaces

Texto completoPetri nets (PN) are currently the most promising approaches to model and to verify complex systems such as Multi Agent Systems (MAS). Several solutions have been proposed to solve the problems of communication, coordination and interaction among Agents. However, to best of our knowledge, none of this solution has able to handle both aspects: structural and behavioral. The thesis focuses on the problem of formal modeling and automatic and semi-automatic verification of properties in Multi Agent Systems. More specifically, the objective is to propose a new original formal model based on Petri nets, Agents Petri nets (APN), which express consistently more accurate a Multi Agent Systems. There is growing interest in the extension of this model for modeling the migration of Agents within the mobile Agent systems. This class of model allows focusing on the formal verification of classical properties such as alertness or absence of deadlock in the context of Multi Agent Systems

Um dos desafios de desenvolvimento de software é produzir aplicativos que são projetados para evoluir reduzindo esforços de manutenção. Diversas técnicas desenvolvidas para a governança de leis de interação em sistemas multiagentes abertos foram propostas, no entanto a flexibilidade e a reutilização de leis não ocorrem de forma sistemática com estas técnicas. A tecnologia de gframeworks visa orientar o projeto e a implementação de leis de interação em sistemas multiagentes abertos, com o objetivo de produzir mecanismos de governança de leis de interação. A flexibilidade em g- frameworks é obtida através da introdução de incrementos específicos que as instâncias em desenvolvimento requerem, de modo a completar e adaptar as funcionalidades originais do g-framework. A reutilização em g-frameworks vem justamente do re-aproveitamento de um mesmo projeto e código de lei de interação em instâncias geradas a partir do g-framework. Os benefícios obtidos por tal abordagem podem impactar positivamente o desenvolvimento de software em termos do custo e tempo total de construção de uma família de mecanismos de governança de sistemas multiagentes. Para isto, são apresentadas técnicas de governança de sistemas multiagentes abertos e técnicas de reutilização de leis de interação. Um método de orientação é proposto para guiar o desenvolvimento de g-frameworks. Experimentos foram desenvolvidos e são descritos neste documento.
One of the challenges of software development is to produce applications that are designed to evolve, reducing maintenance efforts. Many techniques developed to govern the interaction laws in open multi- agent systems were proposed, but the flexibility and reuse concerns of interaction laws were not systemically fulfilled by them. The technology of g- frameworks intends to guide the design and the implementation of interaction laws in open multi-agent systems, aiming to facilitate the production of interaction law governance mechanisms. The flexibility in g-frameworks is achieved by specific increments that the instances under development require, to complete and adapt the original functionalities of the g-framework. The reuse in g- frameworks is related to a common design and codification of that interaction laws that are shared by instances developed with the g-framework. The benefits of this approach might positively impact the development of software considering the costs and the necessary time to construct the family of governance mechanisms of multiagent systems. In this thesis, some techniques to promote reuse of interaction laws were propose to fulfill this goal. One method to orient the development of g-frameworks is proposed. Experiments were developed and they are described in this thesis.

Texto completoLes protocoles collectés au cours de cette expérimentation ont été analysés du point de vue de la planification et du point de vue des interactions. Ainsi, un modèle de la planification humaine et un modèle de l'interaction humaine ont pu être conçus.
Ces deux modèles sont intégrés de façon homogène à une nouvelle architecture d'agent appelée BDIGGY. Parmi les modèles d'agents existants, le modèle BDI (Belief, Desire, Intention) offre un cadre intéressant pour la conception d'agents délibératifs capables de planifier et
d'interagir selon leurs états mentaux. Ainsi, l'architecture BDIGGY est née d'une fusion entre le système IGGY (un système pré-existant de planification humaine) et une architecture BDI étendue à la résolution coopérative de problèmes.
Le modèle de l'interaction humaine introduit dans BDIGGY est sur deux niveaux :
1. il s'appuie sur la théorie des actes de langage pour modéliser les énoncés, à l'aide d'un ensemble de performatives (comme c'est le cas dans les ACL classiques) appliquées à des états mentaux ;
2. il utilise un modèle du discours, représenté par des automates temporisés, pour décrire la dynamique des conversations humaines, en remplacement des protocoles de communication jugés trop rigides.
Les niveaux de l'énoncé et du discours sont liés par une sémantique des performatives. Cette sémantique décrit les pré-conditions et les post-conditions portant sur les états mentaux des agents, à la réception et à l'envoi de messages.
Dans BDIGGY, l'interaction, la planification et les connaissances s'entrelacent grâce auxconcepts BDI.
L'architecture BDIGGY est validée en comparant au cours d'un test "à la Turing", les protocoles expérimentaux provenant de l'expérimentation psychologique et les protocoles générés par des agents BDIGGY, durant une simulation de la résolution du problème.

Texto completoNo matter the scale of observation, biological systems ranging from molecules to cells, and multicellular organisms to communities, manifest collective behaviours. Many explanatory ideas have been put forward based on local perception. In each of these cases progress has been possible because the collective-level phenotype is obvious and observable to the naked eye, but also because of the objective function targeted in the understanding of these behaviours. Here I constructed a machine-ecosystem hybrid that involve an observation device, coupled to a light landscape generator in an automated loop that contain a learning process at every step based on data captured from the ecosystem being observed. In order to break the reality gap between modelisation and reality, taking into account the deep complexity of the studied system as the modelisation can then co evolve with the observed matter, that is reactive toward the adaptive landscape that interact with it, and then reach unexplored and not experimentally implementable fields of heuristic. My project involves several stages. Construction of the hybrid. Application and development interaction algorithms. Establishment of simple microbial populations that can be sustained and whose behaviour can be manipulated via the machine. Experiments to demonstrate proof of principle

Texto completoIf decision making can be a pure individual process, it can involve several actors and present social aspects. In this thesis, I consider two types of social decision process : supported decision making and collective decision making. Concerning supported decision making, two actors have distinct roles : the decision maker and the assistant. Here, the decision maker is a human agent and the assistant a software one. In many applications, the dialogical abilities of the assistant are deceptive and the dialogue lacks of consistency. To tackle this problem, we design a proactive dialogical agent aiming for the credibility in conversation and the relevance of recommandations : our agent leads the conversation in asking relevant questions to collect the preferences of the decision maker and use them in recommending the alternatives that fit the most. We apply our approach on the e-commerce field. The second contribution concerns collective decision. The objective is to define a process that lead to a fair agreement, even if participants have incomplete preferences. For this purpose, I define the fair agreements by applying the leximax criterion on the rank of alternatives. Then, I propose a negotiation protocol to reach such agreements and the strategy is taken into account to evaluate it. Finally, the protocol is applied to the search of a meeting point in a maze

Texto completoLes formalismes existants comme les DEC-POMDPs parviennent à représenter des problèmes multi-agents mais ne représentent pas au niveau individuel la notion d'interaction fondamentale dans les systèmes collectifs. Ceci induit une complexité algorithmique importante dans les algorithmes de résolution. Afin de donner aux agents la possibilité d'appréhender la présence d'autres agents et de structurer de manière implicite les systèmes multi-agents, cette thèse propose un formalisme original, l'interac-DEC-POMDP inspiré des DEC-POMDPs et d'Hamelin, une simulation développée au cours de cette thèse et issue d'expériences conduites en éthologie. La spécificité de ce formalisme réside dans la capacité offerte aux agents d'interagir directement et localement entre eux. Cette possibilité permet des prises de décision à un niveau intermédiaire entre des décisions globales impliquant l'ensemble des agents et des décisions purement individuelles.
Nous avons proposé en outre un algorithme décentralisé basé sur des techniques d'apprentissage par renforcement et une répartition heuristique des gains des agents au cours des interactions. Une démarche expérimentale nous a permis de valider sa capacité à produire pour des restriction du formalisme des comportements collectifs pertinents adaptatifs sans qu'aucun agent ne dispose d'une vue globale du système.

Texto completoIn recent years, video games domains and multiagents systems (MAS) domains took more and more place into the life of many pepole. Despite of strong similarities (video games entities wich can be assimilated to agents), MAS are very rarely used during the development of video games. This submission presents the Shine Agent ModelingPlatform (SAMP), a framework trying to integrate the multi-agents paradigm within the development of video games. The purpose is to integrate the efficiency of the MAS within the video games.SAMP provides an approach to enhance the interactions between agents. This approach reduces the number of searches within the environment. In addition to integrate the multi-agents paradigm within the video games, SAMP aims to be userfriendly by proposing a full graphical interface to MAS. An import/export system of these modelsallows users to create two modeling levels: one close to the computer sciences logic and the second close the business logic of the user.SAMP is integrated in a video games engine: Shine Engine. This integration allows to generate the graphic environment in which agents will live

Texto completoWithin a behavioral approach and given the complexity of financial markets, the aim of this thesis is to examine the extent to which directed networks that governs the interaction among investors as well as their mimicking behavior influence their anticipations and the price dynamics. We propose an artificial asset market populated by chartists and fundamentalists who are allowed to switch from one trading strategy to the other according to their relative performances. Firstly, we study a fully connected network to test for a global interaction. We find that our benchmark model accounts for the emergence of excess volatility of asset prices when chartists dominate the market. Secondly, we restrict our focus to local interactions between investors. We generate a family of network structures that spans regular network, small world network and random network. Thirdly, we introduce a new model that allows us to control (1) the direction of the rewiring process of the links; (2) the randomness of the network; and (3) the asymmetry in its degree distribution by assuming that there are two classes of agents: stars and non-stars. We show that unlike the degree of the randomness of the network, the asymmetry in the degree distribution produces opposite effects depending on whether the network is outward or inward rewired. Finally, we address the question as to how this analysis can be used to produce realistic market dynamics. We find that the presence of a mimicking threshold with a high reaction coefficient provides a better approximation to the characteristics of the distribution of real returns and reproduces the most important stylized facts observed in financial time series

Texto completoAgents in a learning environment can have various roles and social behaviours that can influence the goals and motivation of the learners in distinct ways. Self-regulated learning (SRL) is a comprehensive conceptual framework that encapsulates the cognitive, metacognitive, behavioural, motivational and affective aspects of learning and entails the processes of goal setting, monitoring progress, analyzing feedback, adjustment of goals and actions by the learner. In this thesis, we present a multi-agent learning interaction involving various pedagogical agent roles aiming to improve the self-regulation of the learner while engaging in a socially shared learning activity. We used distinct roles of agents, defined by their social attitudes and competence characteristics, to deliver specific regulation scaffolding strategies for the learner. The methodology followed in this Thesis started with the definition of pedagogical agent roles in a socially shared regulation context and the development of a collaborative learning task to facilitate self-regulation. Based on the learning task framework, we proposed a shared learning interaction consisting of a tutor agent providing external regulation support focusing on the performance of the learner and a peer agent demonstrating co-regulation strategies to promote self-regulation in the learner. A series of user studies have been conducted to understand the learner perceptions about the agent roles, related behaviours and the learning task. Altogether, the work presented in this thesis explores how various roles of agents can be utilised in providing regulation scaffolding to the learners in a socially shared learning context

Texto completoThe Internet of Things (IoT) aims to create a global ubiquitous ecosystem composed of large numbers of heterogeneous devices. To achieve this vision, the World Wide Web is emerging as a suitable candidate to interconnect IoT devices and services at the application layer into a Web of Things (WoT).However, the WoT is evolving towards large silos of things, and thus the vision of a global ubiquitous ecosystem is not fully achieved. Furthermore, even if the WoT facilitates mashing up heterogeneous IoT devices and services, existing approaches result in static IoT mashups that cannot adapt to dynamic environments and evolving user requirements. The latter emphasizes another well-recognized challenge in the IoT, that is enabling people to interact with a vast, evolving, and heterogeneous IoT.To address the above limitations, we propose an architecture for an open and self-governed IoT ecosystem composed of people and things situated and interacting in a global environment sustained by heterogeneous platforms. Our approach is to endow things with autonomy and apply the social network metaphor to createflexible networks of people and autonomous things. We base our approach on results from multi-agent and WoT research, and we call the envisioned IoT ecosystem the Social Web of Things.Our proposal emphasizes heterogeneity, discoverability and flexible interaction in the IoT. In the same time, it provides a low entry-barrier for developers and users via multiple layers of abstraction that enable them to effectively cope with the complexity of the overall ecosystem. We implement several application scenarios to demonstrate these features

As a first step, we have proposed, a mechanism that is based on the analysis of the agents' actions in their plans and reasoning about the plans of others. Additionally, we have addressed the problem of coalition formation with dynamic constraints and preferences that agents reveal and communicate to others during their negotiations. Finally, we have refined our coalition formation mechanism allowing a guided search of the coalitions by building a tree of constraints and a tree of coalitions. Each tree is explored by means of the Monte-Carlo algorithm

It's a Help tool to the decision on the simulation of interactions between stakeholders acting on a territory in the Common-pool resources via an environmental, social and economic interface. The aim of the SIEGMAS is double. on the one hand, It is a matter of giving a generic, model agent re-usable dedicated to the scientific community for the management of natural resources. On the other hand, the aim consists on giving a framework of computer solution adapted to the decision-makers of politic and economic area for the decision making

Texto completoLa plupart des approches segmentent ce traitement en fonction de l'émetteur de la demande (humain ou agent). Nous pensons au contraire qu'il est possible de proposer un modèle d'interaction commun aux deux situations. Ainsi, nous présentons d'abord un algorithme d'interprétation sémantique de la commande indépendant du type d'interaction (humain-agent ou agent-agent). Cet algorithme considère le rapport entre « ce qui est compris » de la commande et « ce qui est possible » pour la machine. Ce rapport intervient dans un système de sélection de réponses basé sur une mesure de degré de relation sémantique. Nous proposons ensuite une telle mesure, conçue pour prendre en compte plus d'informations que la plupart des mesures actuelles.
Nous étudions ensuite les implémentations que nous avons faites dans les cadres humain-agent et agent-agent. Pour l'implémentation humain-agent, l'une des spécificités est l'utilisation d'une langue naturelle, impliquant le besoin d'utiliser des outils de modélisation de la langue. Pour l'implémentation agent-agent, nous proposerons une adaptation de notre architecture, en s'appuyant sur des protocoles d'interactions entre agents.

Texto completoWith the widespread use of Artificial Intelligence (AI) systems, understanding the behavior of intelligent agents and robots is crucial to guarantee smooth human-agent collaboration since it is not straightforward for humans to understand the agent’s state of mind. Recent studies in the goal-driven Explainable AI (XAI) domain have confirmed that explaining the agent’s behavior to humans fosters the latter’s understandability of the agent and increases its acceptability. However, providing overwhelming or unnecessary information may also confuse human users and cause misunderstandings. For these reasons, the parsimony of explanations has been outlined as one of the key features facilitating successful human-agent interaction with a parsimonious explanation defined as the simplest explanation that describes the situation adequately. While the parsimony of explanations is receiving growing attention in the literature, most of the works are carried out only conceptually.This thesis proposes, using a rigorous research methodology, a mechanism for parsimonious XAI that strikes a balance between simplicity and adequacy. In particular, it introduces a context-aware and adaptive process of explanation formulation and proposes a Human-Agent Explainability Architecture (HAExA) allowing to make this process operational for remote robots represented as Belief-Desire-Intention agents. To provide parsimonious explanations, HAExA relies first on generating normal and contrastive explanations and second on updating and filtering them before communicating them to the human.To evaluate the proposed architecture, we design and conduct empirical human-computer interaction studies employing agent-based simulation. The studies rely on well-established XAI metrics to estimate how understood and satisfactory the explanations provided by HAExA are. The results are properly analyzed and validated using parametric and non-parametric statistical testing

Texto completoWe discuss in this thesis about designing an computer system for an evaluative support , to support and evaluate in real-time the collaborative activity in the particular case of "an activity governed by processes from different organizations". We define a process as a set of rules, policies, plans, standards which aim to guide and be a reference for the realization of a collaborative activity. Our research is applied to training in crisis management, and situated in the technological context of tangible interaction.To implement a flexible and comprehensible evaluative support, we propose a socio-technical systemfor bringing the actors shared and distributed organizational consciousness.In this context, three key issues are considered: (1) representation and management of the contexts associated with the sustained activity and the interactions between the involved stakeholders, (2) representation and management of various processes associated with the sustained activity and the interaction and (3) the articulation between the sustained activity and the interaction.To answer these issues, we offer the OrA system based on three groups of principles, both about sutained activiy and interaction : modularity and representation of processes and contexts, autonomous management and loosely coupled processes and contextual elements, flexible coordination between these process and context management mechanisms.These principles are implemented in a computer system based on the model of groupware, especially CLOVER, a traces models, and normative multi-agent systems.This system is evaluated by demonstrating the ability to model the process of a practical case of crisis management exercise, and by providing a use situation of a real exercise training in crisis management

Texto completoThis thesis is a study of different kinds of interaction in multi-agent systems. We try to define a general and operationnal model of interaction in these systems. This work has several goals. We review the state of the art in interaction modelling, and we try to classify these interaction models according to several criterions. We then try to synthetize these works in order to obtain the highest level, still operationnal, interaction model. We then realize an implantation of this model, capable of interfacing itself with a vast array of multi-agent systems (based on the Java langage). Our operationnal model can then be used and parametrized by way of a formal grammar : a grammar of interaction definition for multi-agent systems that we introduce

Texto completoOver the last few years, the advances in management science and information technology have transformed the business process management (BPM) discipline into an important topic for both industry and academy. BPM uses business processes as the means for improving the operational performance of organizations, and setting processes are at the heart of BPM allows linking together people, systems, and different organizations to deliver value to stakeholders. The target of our work is the family of BPM systems. A BPM system is a generic software system that is driven by explicit process designs to enact and manage operational business processes. Despite the wide range of topics addressed by the academy on business processes, there are still aspects not addressed by prior research. A particular problem in this regard is the mediation between BPM systems and humans. Human interaction in those systems follows a standard user interface based predominantly on work item lists and forms. Thus, there is little room for creativity for users. They have not only difficulties in enacting their processes but also for searching the most suitable one for their needs. It would be more efficient to let humans interact in natural language. However, process modeling languages are an insufficient means of capturing and representing the domain of discourse. The present thesis develops an original approach to agent dialog management for the problem of business process enactment. The overarching motivation for this work was to design a dialog model scalable to different domains. The model relies on domain and business process ontologies, and necessitates a minimum effort of adaptation on ontologies to improve the interaction. Results indicate the potential of our agent-based approach to generate natural language

Texto completoMaps show geographic information of a given area in a simplified way, particularly when the scale is small. The simplification process, called cartographic generalisation, is submitted to several constraints : legibility, adequation to the abstraction level, and consistency with reality. The will to automate the maps creation process from geographical databases led to the creation of algorithms allowing the simplification object by object. However the choice of the algorithms, as their settings, are influenced by the object on which it is applied, and by the other objects in relation with this object (e.g. a building close to another one, a road parallel to a buildings alignment). This motivates the use of multi-agents models for automated map generalisation. Several multi-agent models were proposed, each of them having a different approach to manage multi-levels relations. Here, what we call a level is, for instance, the distinction between individual agents, like a building, and agents representing a group of other agents, like a urban block composed by the surrounding roads and buildings inside.We study the unification of existing models, using the multi-level paradigm PADAWAN, in order to simplify interactions between agents in different levels. We propose the DIOGEN model, in which the principle of interactions between agents of different levels is adapted to cartographic generalisation guided by constraints, those allowing to unify the existing models AGENT, CartACom and GAEL, and giving promising features.We evaluate our proposal on different case studies. Among them, we study the generalisation of trekking maps, where the routes are symbolized individually by a different couloured line symbols, like on bus maps. The presence of several route symbols on a same road leads to specific generalisation issues, like the choice of the side of each route symbol position, or the implications for the other objects on the map (e.g. points of interest, buildings) under the route symbol – issues tackled using our proposal of formal multi-levels representation.This work leads us to the identification of recurrent behaviours. We express them as analysis patterns, in a way that is independent from cartographic generalisation and constraint solving problems
