    Mining Frequent Instances on Workflows

    A workflow is a partial or total automation of a business process, in which a collection of activities must be executed by humans or machines, according to certain procedural rules. This paper deals with an aspec...

    Reasoning on Workflow Executions

    This paper presents a new formalism for modelling workflows schemes which combines a control flow graph representation with simple (i.e., stratified), yet powerful DATALOG rules to express complex properties and ...

    Mining Expressive Process Models by Clustering Workflow Traces

    We propose a general framework for the process mining problem which encompasses the assumption of workflow schema with local constraints only, for it being applicable to more expressive specification languages...

    An Ontology-Driven Process Modeling Framework

    Designing, analyzing and managing complex processes are recently become crucial issues in most application contexts, such as e-commerce, business process (re-)engineering, Web/grid computing. In this paper, we...

    An Information-Theoretic Framework for High-Order Co-clustering of Heterogeneous Objects

    The high-order co-clustering problem, i.e., the problem of simultaneously clustering several heterogeneous types of domains, is usually faced by minimizing a linear combination of some optimization functions eval...

    Mining Constrained Graphs: The Case of Workflow Systems

    Constrained graphs are directed graphs describing the control flow of processes models. In such graphs, nodes represent activities involved in the process, and edges the precedence relationship among such acti...

    Outlier Detection Techniques for Process Mining Applications

    Classical outlier detection approaches may hardly fit process mining applications, since in these settings anomalies emerge not only as deviations from the sequence of events most often registered in the log, ...

    Discovering Multi-perspective Process Models: The Case of Loosely-Structured Processes

    Process Mining techniques exploit the information stored in the execution log of a process to extract some high-level process model, useful for analysis or design tasks. Most of these techniques focus on “stru...
