PETRA: Process Evolution using a TRAce-based system on a maintenance platform

To meet increasing needs in the field of maintenance, we studied the dynamic aspect of process and services on a maintenance platform, a major challenge in process mining and knowledge engineering. Hence, we propose a dynamic experience feedback approach to exploit maintenance process behaviors in real execution of the maintenance platform. An active learning process exploiting event log is introduced by taking into account the dynamic aspect of knowledge using trace engineering. Our proposal makes explicit the underlying knowledge of platform users by means of a trace-based system called “PETRA”. The goal of this system is to extract new knowledge rules about transitions and activities in maintenance processes from previous platform executions as well as its user (i.e. maintenance operators) interactions. While following a Knowledge Traces Discovery process and handling the maintenance ontology IMAMO, “PETRA” is composed of three main subsystems: tracking, learning and knowledge capitalization. The capitalized rules are shared in the platform knowledge base in order to be reused in future process executions. The feasibility of this method is proven through concrete use cases involving four maintenance processes and their simulation

Student's intention to use wikis for Online Collaborative Learning (OCL)

Online Collaborative Learning (OCL) is very prominent nowadays. Even though OCL is utilized all over the globe, there are still limitations in evaluating the factors influencing intention to use tools and technologies of online collaborative learning, especially in Malaysia. This study aimed to investigate factors affecting the intention to use Wikis for OCL through the Unified Theory of Acceptance and Use of Technology (UTAUT) has been adopted in designing the theoretical framework for the study. This framework is applied to examine the significant differences between level of study related to factors affecting the intention to use Wikis namely the performance expectancy, effort expectancy, social influence, the features of OCL and intention to use. A survey was used to collect usable data from 233 undergraduate students in a Universiti Teknologi Malaysia. Structural Equation Modeling (SEM) was used as the technique for data analysis. The results show that all construct was significant predictors of intention to use Wikis. Overall, the proposed model achieves an acceptable fit and explains its variance for 66% of sample. The implications of the study‟s findings for practice and research are discussed, and avenues for future research outlined

Modeling and exploitation of the traces of interactions in the collaborative working environment

Les sciences humaines et le progrès social ne peuvent pas se poursuivre sans collaboration. Avec le développement rapide des technologies de l'information et la popularité des appareils intelligents, le travail collaboratif est beaucoup plus simple et plus fréquents que jamais. Les gens peuvent travailler ensemble sans tenir compte de leur emplacement/ location géographique ou de la limitation de temps. Les environnements de travail de collaboration basés sur le Web sont conçus et consacrés à supporter/soutenir le travail individuel et le travail en groupe dans divers domaines: la recherche, les affaires, l'éducation, etc. N'importe quelle activité dans un système d'information produit un ensemble de traces. Dans un contexte de travail collaboratif, de telles traces peuvent être très volumineuses et hétérogènes. Pour un Environnement de Travail Collaboratif (ETC) typique Basé sur le Web, les traces sont principalement produites par des activités collaboratives ou des interactions collaboratives et peuvent être enregistrées. Les traces modélisées ne représentent pas seulement la connaissance, mais aussi l'expérience acquise par les acteurs via leurs interactions mutuelles ou les interactions qu'ils ont avec le système. Avec la complexité croissante de la structure de groupe et les besoins fréquents de collaboration, les interactions existantes deviennent de plus en plus difficiles à saisir et à analyser. Or, pour leurs travaux futurs, les gens ont souvent besoin de récupérer des informations issues de leurs activités de collaboration précédentes. Cette thèse se concentre sur la définition, la modélisation et l'exploitation des différentes traces dans le contexte d'Environnement de Travail Collaboratif et en particulier aux Traces Collaboratives dans l'espace de travail partagé de groupe (ou l'espace de travail collaboratif). Un modèle de traces de collaboration qui peuvent efficacement enrichir l'expérience du groupe et aider à la collaboration de groupe est proposé et détaillé. Nous présentons ensuite et définissons un type de filtre complexe comme un moyen possible d'exploiter ces traces. Plusieurs scénarios de base d'exploitation des traces collaboratives sont présentés. Pour chacun d'entre eux, nous présentons leurs effets et les avantages procurés par ces effets dans l'environnement de travail collaboratif. En effet, un cadre de l'exploitation des traces général est introduit et nous expliquons mis en œuvre dans un ETC. Trois approches collaboratives générant des traces sont discutées à l'aide d'exemples: l'Analyse SWOT, l'intégration de modèle de maturité de la capacité (CMMI) et le Système de Recommandation de Groupe. Une expérimentation de ce modèle a été réalisée dans le cadre de la plate-forme collaborative E-MEMORAe2.0. Cette expérience montre que notre modèle de trace collaborative et le cadre d'exploitation proposé pour l'environnement de travail collaboratif peuvent faciliter à la fois le travail personnel et de groupe. Notre approche peut être appliquée comme un moyen générique pour traiter différents sujets et problèmes, qu'il s'agisse de collaboration ou de l'exploitation des traces laissées dans un ECT.Human science and social progress cannot continue without collaboration. With the rapid development of information technologies and the popularity of smart devices, collaborative work is much simpler and more common than ever. People can work together irrespective of their geographical location or time limitation. In recently years, Web-based Collaborative Working Environments (CWE) are designed and devoted to support both individual and group work to a greater extent in various areas: research, business, learning and etc. Any activity in an information system produces a set of traces. In a collaborative working context, such traces may be very voluminous and heterogeneous. For a typical Webbased Collaborative Working Environment, traces are mainly produced by collaborative activities or interactions and can be recorded. The modeled traces not only represent knowledge but also experience concerning the interactive actions among the actors or between actors and the system. With the increasing complexity of group structure and frequent collaboration needs, the existing interactions become more difficult to grasp and to analyze. And for the future work, people often need to retrieve more information from their previous collaborative activities. This thesis focuses on defining, modeling and exploiting the various traces in the context of CWE, in particular, Collaborative Traces (CTs) in the group shared/collaborativeworkspace. A model of collaborative traces that can efficiently enrich group experience and assist group collaboration is proposed and detailed. In addition, we introduce and define a type of complex filter as a possible means to exploit the traces. Several basic scenarios of collaborative traces exploitation are presented describing their effects and advantages in CWE. Furthermore, a general traces exploitation framework is introduced and implemented in CWE. Three possible traces based collaborative approaches are discussed with comprehensive examples: SWOT Analysis, Capability Maturity Model Integration (CMMI) and Group Recommendation System. As a practical experience we tested our model in the context of the E-MEMORAe2.0 collaborative platform. Practical cases show that our proposed CT model and the exploitation framework for CWE can facilitate both personal and group work. This approach can be applied as a generic way for addressing different types of collaboration and trace issues/problems in CWE.COMPIEGNE-BU (601592101) / SudocSudocFranceF

Modelo para el diseño de sistemas gestores de workflows con funcionalidades colaborativas, cloud y móviles

This research was developed in the context of WFMS (Workflow Management Systems), mobile applications, cloud computing, and collaborative systems. Currently the design of WFMS is based on the reference model proposed by the WfMC (Workflow Management Coalition). The problem that exists today in the design and development of WfMS is that the reference model proposed by the WfMC was designed many years before the rise of mobile technologies, cloud computing and collaborative systems. It is important to create a new model for the design of WfMS taking in to account the new technological features and functionalities offered by mobile devices, collaborative and cloud computing services along with new paradigms of collaboration that can occur when using these technological solutions. This research has the general objective of obtain a model for the design of WfMS with Collaborative, Cloud and Mobile functionalities.
