La communaut\u00e9 BPM a reconnu son potentiel pour am\u00e9liorer la gestion des processus m\u00e9tier (BPM) et favoriser les collaborations inter-organisationnelles. Malgr\u00e9 des recherches approfondies sur l&rsquo;ex\u00e9cution des processus d&rsquo;affaires bas\u00e9s sur la blockchain, l&rsquo;exploration de donn\u00e9es de la blockchain pour le process mining a r\u00e9cemment commenc\u00e9 \u00e0 \u00eatre explor\u00e9e. Les \u00e9tudes actuelles se concentrent principalement sur les processus centr\u00e9s sur les activit\u00e9s, n\u00e9gligeant souvent les processus centr\u00e9s sur les artefacts pr\u00e9valents dans les applications blockchain. Les formats de journalisation traditionnels comme XES, bien que couramment utilis\u00e9s, rencontrent des d\u00e9fis tels que la perte d&rsquo;information et la d\u00e9normalisation lorsqu&rsquo;ils sont appliqu\u00e9s \u00e0 des donn\u00e9es centr\u00e9es sur les artefacts. L&rsquo;introduction d&rsquo;OCEL a partiellement abord\u00e9 ces probl\u00e8mes en permettant le stockage de donn\u00e9es d&rsquo;\u00e9v\u00e9nements centr\u00e9es sur les objets, mais il manque de prise en charge pour l&rsquo;\u00e9volution et les relations des objets. Cette th\u00e8se rel\u00e8ve ces d\u00e9fis en proposant ACEL, une extension d&rsquo;OCEL qui prend en charge de mani\u00e8re compl\u00e8te le stockage des donn\u00e9es d&rsquo;\u00e9v\u00e9nements centr\u00e9es sur les artefacts.

The BPM community recognized its potential for enhancing business process management (BPM) and fostering inter-organizational collaborations. Despite extensive research on blockchain-based business process execution, process mining from blockchain data has recently begun to be explored. Current studies mainly focus on activity-centric processes, often overlooking artifact-centric processes prevalent in blockchain applications. Traditional logging formats like XES, while commonly used, face challenges like information loss and denormalization when applied to artifact-centric data. The introduction of OCEL partially addressed these issues by enabling the storage of object-centric event data, but it lacks support for object evolution and relations. This thesis addresses these challenges by proposing ACEL, an extension of OCEL that comprehensively supports artifact-centric event data storage. We present an artifact-centric method to gather event data from blockchain applications, converting them into ACEL logs. The approach&rsquo;s viability is assessed using Cryptokitties and Augur Ethereum applications. We initially compare ACEL&rsquo;s process mining capabilities with OCEL, and then introduce a discovery method using hierarchical clustering and information gain analysis to derive GSM models, the standard for artifact-centric processes. Our evaluation on Cryptokitties confirms the feasibility of this approach and highlights the advantages of ACEL in artifact-centric process mining.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ecole Doctorale de l&rsquo;Institut Polytechnique de Paris et le Laboratoire de recherche SAMOVAR &#8211; Services r\u00e9partis,
