Completing Workflow Traces Using Action Languages

摘要

The capability to monitor process and service executions, which has gone to notably increase in the last decades due to the growing adoption of IT-systems, has brought to the diffusion of several reasoning-based tools for the analysis of process executions. Nevertheless, in many real cases, the different degrees of abstraction of models and IT-data, the lack of IT-support on all the steps of the model, as well as information hiding, result in process execution data conveying only incomplete information concerning the process-level activities. This may hamper the capability to analyse and reason about process executions. This paper presents a novel approach to recover missing information about process executions, relying on a reformulation in terms of a planning problem.
