    Providing Reliability for Transactional Mobile Agents
    (Vincent Guyot, 2013) Zeghache, Linda; Hurfin, Michel; Moise, Izabela; Badache, Nadjib
    A transactional agent is a mobile agent that migrates from a site to another one in order to execute a distributed transaction assigned by a user. Works on transactional mobile agents have identified two prob- lems that can not be solved by the agent alone. The first one is related to the reliability. The lack of a fault tolerant infrastructure and method- ologies that address fault tolerant execution of mobile agents highlights a major drawback of this technology. The second problem for which the agent needs assistance is related to the atomic validation of the transac- tion. In this paper we address the mobile agent fault tolerance and the transactional support

    Semantic Annotations and Context Reasoning to Enhance Knowledge Reuse in e-Learning
    (Springer Berlin Heidelberg, 2013) Boudebza, Souad; Berkani, Lamia; Azouaou, Faiçal; Nouali, Omar
    We address in this paper the need of improving knowledge reusability within online Communities of Practice of E-learning (CoPEs). Our approach is based on contextual semantic annotations. An ontological-based contextual semantic annotation model is presented. The model serves as the basis for implementing a context aware annotation system called “CoPEAnnot”. Ontological and rule-based context reasoning contribute to improving knowledge reuse by adapting CoPEAnnot’s search results, navigation and recommendation.The proposal has been experimented within a community of learners.
