Discovering the business processmodel from an organisation's records of its operational processes is an active area of research in process mining. The discovered model may be used either during a new system rollout or to improve an existing system. In this paper, we present a process model discovery approach based on the recently proposed bio-inspired Manta Ray Foraging Optimization algorithm (MRFO). Since MRFO is designed to solve real-valued optimization problems, we adapted a binary version of MRFO to suit the domain of process mining. The proposed approach is compared with state-of-the-art processdiscovery algorithms on several synthetic and real-life event logs. The results show that compared to other algorithms, the proposed approach exhibits faster convergence and yields superior quality processmodels.

process model discovery has gained a lot of attention in recent years, to mine a processmodel from traces of process executions. In our recent work, we have proposed SIM (Semantic Interactive Miner), an innovative process mining tool able to discover the processmodel in an incremental way: first, a mining module builds an initial processmodel, called log-tree, from the available traces;then, such a model is refined interactively with domain experts, through merge and abstraction operations. However, in several contexts, traces are richer: they do not record only actions, but also states (i.e., values of parameters possibly affected by the actions). A typical example is the medical domain, where traces contain both actions and measurements of patients' parameters. In this paper, we propose AS-SIM (Action-State SIM), the first approach aiming at discovering a comprehensive model, in which two distinct classes of nodes are considered, to capture both actions and states. We focus on the definition and on the discovery of the initial action-state processmodel (called action-state log-tree), while in our future work we will extend SIM's merge and abstraction operations accordingly.

process model discovery covers the different methodologies used to mine a processmodel from traces of process executions, and it has an important role in artificial intelligence research. Current approaches in this area, with a few exceptions, focus on determining a model of the flow of actions only. However, in several contexts, (i) restricting the attention to actions is quite limiting, since the effects of such actions also have to be analyzed, and (ii) traces provide additional pieces of information in the form of states (i.e., values of parameters possibly affected by the actions);for instance, in several medical domains, the traces include both actions and measurements of patient parameters. In this paper, we propose AS-SIM (Action-State SIM), the first approach able to mine a processmodel that comprehends two distinct classes of nodes, to capture both actions and states.

process Mining is a research field that aims to develop new techniques to discover, monitor and improve real processes by extracting knowledge from event logs. This relatively young research discipline has evidenced efficacy in various applications, especially in application domains where a dynamic behavior needs to be related to processmodels. process model discovery is presumably the most important task in process Mining since the discovered models can be used as an objective starting points for any further process analysis to be conducted. There are various quality dimensions the model should consider during discovery such as Replay-Fitness, Precision, Generalization, and Simplicity. It becomes evident that process model discovery, with its current given settings, is a Multi-Objective Optimization Problem. However, most existing techniques does not approach the problem as a Multi-Objective Optimization Problem. Therefore, in this work we propose the use of one of the most robust and widely used Multi-Objective Optimizers in process model discovery, the NSGA-II algorithm. Experimental results on a real life event log shows that the proposed technique outperforms existing techniques in various aspects. Also this work tries to establish a benchmarking system for comparing results of Multi-Objective Optimization based process model discovery techniques.

Business process model discovery targets the construction of conceptual models from event data that has been recorded during the execution of a business process. While a plethora of discovery techniques have been proposed in the literature, most existing techniques fail to cope with complex control-flow patterns as they are observed in event logs of highly flexible processes. In this paper, we follow the idea of splitting-up an event log into sub-logs, before applying process model discovery. This yields a set of sub-processmodels, one per sub-log, each describing a major variant of the business process. Unlike existing techniques, our clustering approach is guided by the result of modeldiscovery: It first optimises the average complexity of the resulting models, before improving the accuracy of each model in isolation. Our experimental evaluation highlights that our approach yields more accurate sub-processmodels (that are of comparatively low complexity) than state-of-the-art trace clustering techniques.

As proven in recent research on personal knowledge management (PKM) processes in online learning environment, this study took the initiative to prove that these processes happen in the said platform by reducing the biasness in respondents' feedbacks. This paper proposes the usage of process mining technique to discover the PKM model in real online learning platform, by analysing the event logs data retrieved from two-semester duration of academic calendar. The focus of this paper is on how the online activities being mapped to the PKM processes, in which the GUSC model has been used as the appropriate model to represent PKM. GUSC model is based on the common processes of get knowledge, understand knowledge, share knowledge and connect to knowledge source, as proven to be construed at granular level in intelligent multi-agent system. Since there was a gap between the unconfirmed reality of the GUSC processes in online platform and the construed GUSC processes at intelligent software level, this study significantly contributes to the closure of this gap with its results and findings. It is discovered that PKM model does exist in online learning environment, with the right mapping of the online activities to the GUSC processes.

alpha-algorithm is able to discover a large class of workflow (WF) nets based on the behavior recorded in event logs, with the main limiting assumption that the event log is complete. Our research has been aimed at finding ways of business processmodels discovering based on examples of traces, i.e., logs of workflow actions that do not meet the requirement of completeness. In this aim, we have modified the existing and introduced a new relation between activities recorded in the event log, which has led to a partial correction of the processmodels discovering techniques, including the alpha-algorithm. We have also introduced the notions of causally and weakly complete logs, from which our modified algorithm can produce the same result as the original algorithm from complete logs. The effect of these modifications on the speed of the processmodel discovering is mostly evident for business processes in which many activities can be performed in parallel. Therefore, this paper presents preliminary results obtained from the investigation of opportunities to discover models of parallel processes based on incomplete event logs.
