A group learning management method for intelligent tutoring systems

In this paper we propose a group management specification and execution method that seeks a compromise between simple course design and complex adaptive group interaction. This is achieved through an authoring method that proposes predefined scenarios to the author. These scenarios already include complex learning interaction protocols in which student and group models use and update are automatically included. The method adopts ontologies to represent domain and student models, and object Petri nets to specify the group interaction protocols. During execution, the method is supported by a multi-agent architecture

A Framework for an adaptive grid scheduling: an organizational perspective

Grid systems are complex computational organizations made of several interacting components evolving in an unpredictable and dynamic environment. In such context, scheduling is a key component and should be adaptive to face the numerous disturbances of the grid while guaranteeing its robustness and efficiency. In this context, much work remains at low-level focusing on the scheduling component taken individually. However, thinking the scheduling adaptiveness at a macro level with an organizational view, through its interactions with the other components, is also important. Following this view, in this paper we model a grid system as an agent-based organization and scheduling as a cooperative activity. Indeed, agent technology provides high level organizational concepts (groups, roles, commitments, interaction protocols) to structure, coordinate and ease the adaptation of distributed systems efficiently. More precisely, we make the following contributions. We provide a grid conceptual model that identifies the concepts and entities involved in the cooperative scheduling activity. This model is then used to define a typology of adaptation including perturbing events and actions to undertake in order to adapt. Then, we provide an organizational model, based on the Agent Group Role (AGR) meta-model of Freber, to support an adaptive scheduling at the organizational level. Finally, a simulator and an experimental evaluation have been realized to demonstrate the feasibility of our approach

Flexible and Emergent Workflows using Adaptive Agents

International audienceMost of existing workflow systems are rigid since they require to completely specify processes before their enactment and they also lack flexibility during their execution. This work proposes to view a workflow as a set of cooperative and adaptive agents interleaving its design and its execution leading to an emergent workflow. We use the theory of Adaptive Multi-Agent Systems (AMAS) to provide agents with adaptive capabilities and the whole multi-agent system with emergent "feature". We provide a meta-model linking workflow and AMAS concepts, and the specification of agent behavior and the resulting collaborations. A simulator has been implemented with the Make Agent Yourself platform

An Anticipative Effects-Based Approach (AEBA) for analyzing collaborative crisis management process

This paper aims at presenting an Anticipative Effects-Based Approach (AEBA) to evaluate the potential effects of a collaborative crisis management process response on the different elements concerned by the crisis evolution. This approach provides several concepts, model and reasoning mechanisms presented and illustrated in this paper. AEBA is currently developed within the French ISYCRI1 Project. It focuses on crisis occurring suddenly and unpredictably. Long time crisis such as famine, pandemic, enduring civilian wars, etc. are not taken into account

Do Process-based Systems Support Emergent, Collaborative and Flexible Processes? Comparative Analysis of Current Systems

Advanced process-based applications such as crisis and risk management require Emergent, Collaborative and Flexible (ECF) processes. These three features correspond to specific real-world requirements. Firstly, to face unpredictable situations, emergent processes are needed, i.e. processes whose model/schema is (partially) unknown at design-time and gradually defined/refined at run-time. Secondly, the complexity of the application domain being addressed requires collaborative processes, i.e. processes whose definition and enactment require interactions between groups of actors using their skills and experiences to make the process convergence towards their common goal. Thirdly, to adapt to the frequent changes that occur in their operating environment, flexible processes are needed, i.e. processes whose model/schema can be modified in real time. The objective of this paper is to present a literature review to study the state of the art of process-based systems with a focus on the three above mentioned properties. Our approach is to specify real world requirements, then to discuss the adequacy of current systems to these requirements and finally to provide advices for their improvement. Examined systems fall within the following areas: Business Process Management (BPM), Adaptive Case Management (ACM), Computer Supported Collaborative Work (CSCW) and Knowledge Management (KM). The paper concludes on the insufficiency of existing systems and the need for designing and implementing a specific process-based system that integrates these three properties in a coherent framework

Accès à l’information dans les réseaux sociaux : quelles formes de collaboration ?

National audienceThis paper presents an exploratory analysis attempting to highlight patterns of col- laboration in social medias. Particularly, we focus on crisis management through the Twitter social platform. We rely on two types of crisis: a natural disaster (Sandy hurricane) and a san- itary crisis (Ebola). We proceed in a three step-methodology consisting in 1) analysing the collaboration structure, 2) then identifying topics of collaboration and 3) finally presenting an overview of the latent collaboration network. Results highlight that collaboration is generally performed in a small network while characterized by diversified topics.Nous présentons dans cet article une analyse exploratoire dans l’objectif d’identifier les patrons de collaboration au sein des réseaux sociaux pour l’accès à l’information. Nous nous focalisons sur le cas de la gestion de crise au travers de la plateforme sociale Twitter. Nous nous appuyons ainsi sur deux types de crises : une catastrophe naturelle (l’ouragan Sandy) et une crise sanitaire (Ebola). Nous proposons une méthodologie en trois étapes qui permet 1) d’analyser les structures de collaboration, 2) d’identifier les thématiques de collaboration et 3) de présenter les réseaux latents de collaboration sur l’ensemble du réseau. Les résultats montrent paradoxalement que le périmètre de la collaboration est réduit, que les sujets sous- jacents sont diversifiés et impliquent des utilisateurs qui peuvent être à l’interface de différents sujets

Interaction protocols for human-driven crisis resolution processes

This work aims at providing a crisis cell with process-oriented tools to manage crisis resolutions. Indeed, the crisis cell members have to define the crisis resolution process, adapt it to face crisis evolutions, and guide its execution. Crisis resolution processes are interaction-intensive processes: they not only coordinate the performance of tasks to be undertaken on the impacted world, but they also support regulatory interactions between possibly geographically distributed crisis cell members. In order to deal with such an interweaving, this paper proposes to use Interaction Protocols to both model formal interactions and ease a cooperative adaptation and guidance of crisis resolution processes. After highlighting the benefits of Interaction Protocols to support this human and collective dimension, the paper presents a protocol meta-model for their specification. It then shows how to suitably integrate specified protocols into crisis resolution processes and how to implement this conceptual framework into a service oriented architecture
