Discovering block-structured process models from event logs -- A constructive approach

by S. J. J. Leemans, D. Fahland, Wil M. P. van der Aalst , 2013
"... Process discovery is the problem of, given a log of observed behaviour, finding a process model that ‘best’ describes this behaviour. A large variety of process discovery algorithms has been proposed. However, no existing algorithm guarantees to return a fitting model (i.e., able to reproduce all ob ..."

We present an extensible framework to discover from any given log a set of block-structured process models that are sound and fit the observed behaviour. In addition we characterise the minimal information required

Workflow Mining: Discovering process models from event logs

by W.M.P. van der Aalst, A.J.M.M. Weijter, L. Maruster - IEEE Transactions on Knowledge and Data Engineering , 2003
"... Contemporary workflow management systems are driven by explicit process models, i.e., a completely specified workflow design is required in order to enact a given workflow process. Creating a workflow design is a complicated time-consuming process and typically there are discrepancies between the ac ..."

The process group approach to reliable distributed computing

"... ABSTRACT Using dealer's quotes and transactions prices on straight industrial bonds, we investigate the determinants of credit spread changes. Variables that should in theory determine credit spread changes have rather limited explanatory power. Further, the residuals from this regression are ..."

changes. Below, we investigate the determinants of credit spread changes. From a contingent-claims, or noarbitrage standpoint, credit spreads obtain for two fundamental reasons: 1) there is a risk of default, and 2) in the event of default, the bondholder receives only a portion of the promised payments

Mining Process Models from Workflow Logs

by Rakesh Agrawal, Dimitrios Gunopulos, Frank Leymann , 1998
"... Modern enterprises increasingly use the workflow paradigm to prescribe how business processes should be performed. Processes are typically modeled as annotated activity graphs. We present an approach for a system that constructs process models from logs of past, unstructured executions of the given ..."

Discovering process models from unlabelled event logs,” in

by Diogo R. Ferreira, Daniel Gillblad - Reijers, Eds , 2009
"... Abstract. Existing process mining techniques are able to discover process models from event logs where each event is known to have been produced by a given process instance. In this paper we remove this restriction and address the problem of discovering the process model when the event log is provid ..."

"... Process mining is the automated acquisition of process models from the event logs of information systems. Although process mining has many useful applications, not all inherent difficulties have been sufficiently solved. A first difficulty is that process mining is often limited to a setting of non- ..."

This information is used to attribute timing such as queue times to the discovered workflow model. The approach is based on Petri nets

Mining CPN Models: Discovering Process Models with Data from Event Logs

by A. Rozinat, R. S. Mans - In Workshop and Tutorial on Practical Use of Coloured Petri Nets and the CPN , 2006

Starting from a process model, which can be discovered by conventional process mining algorithms, we analyze how data attributes influence the choices made in the process based on past process executions using decision mining, or decision point analysis. In this paper we describe how
