Process mining is a family of techniques in the field of process management that support the analysis of business processes based on event logs. During process mining, specialized data mining algorithms are applied to event log data in order to identify trends, patterns and details contained in event logs recorded by an information system. Process Mining research is concerned with the extraction of knowledge about a (business) process from its process execution logs. Process Mining strives to gain insight into various perspectives, such as the process (or control flow) perspective, the performance, data, and organizational perspective (The processmining.org web site has more in ...
A Polynomial-Time Alpha-Algorithm for Process Mining Albana Roci [email protected] Reggie Davidrajuh [email protected] Electrical and Computer Engineering University of Stavanger Stavanger, Norway Abstract — This paper presents an efficient Alpha-algorithm for process mining. Firstly, a short literature review is given on the Process mining is the missing link between model-based process analysis and data-oriented analysis techniques. Through concrete data sets and easy to use software the course provides data science knowledge that can be applied directly to analyze and improve processes in a variety of domains.
The course covers the three main types of process mining. 1. The first type of process mining is discovery. A discovery technique takes an event log and produces a process model without using any a-priori information. An example is the Alpha-algorithm that takes an event log and produces a process model (a Petri net) explaining the behavior ... approaches to process mining, and apply it to the well-known Alpha Algorithm. We show that knowledge of model structures and algorithm behaviour can be used to predict the number of traces needed for mining. Keywords: Business process mining, probabilistic automata, Petri nets. 1 Introduction

INTRODUCTION B Usiness process mining, or process mining in a short form, is an emerging research area, which brings a new way of analyzing and aims to improve the business Process Discovery. Process Discovery is a technique for deriving a process model from log data. Input: execution logs as ordered lists of activities with time stamp and case id. Output: process model which could have generated the execution logs. The caseidisoften not directlycovered in thedata, andneedstobegenerated in pre-processing
The α-algorithm is an algorithm used in process mining, aimed at reconstructing causality from a set of sequences of events. It was first put forward by van der Aalst, Weijters and Măruşter. Several extensions or modifications of it have since been presented, which will be listed below.

our case, the mining algorithm is the -algorithm. During post-processing, the discovered model (in our case a Petri-net) can be ne-tuned and a graphical representation can be build. The focus of most research in the domain of process mining is on mining heuristics based on ordering relations of the events in the process log (cf. Sec-tion 5). So we're still in the process discovery bridge between the observed data and discovering a process model but now with the alpha miner in ProM. So in the previous lecture, I've shown you that this is the Petri net that we expect from the alpha miner, given that it discovers this footprint matrix given the input data.

So the alpha miner is actually the very first algorithm that bridges the gap between event logs, or observed data, and the discovery of a process model. And since it was the very first algorithm to be created, it also has its flaws, but it was a good starting point to continue on. So the alpha miner has a few main steps. Mining with User Interaction ... a net is generated from a log ﬁle by a liberal mining algorithm such as the alpha-algorithm. Then, using concepts from the theory of ... One main difﬁculty of process discovery is that a typical log contains only example runs of the recorded process (we do not discuss the problem of noise here), i.e. logs are
An example is the Alpha-algorithm that takes an event log and produces a process model (a Petri net) explaining the behavior recorded in the log. 2. The second type of process mining is conformance. After the mining-step you should see a matrix with the results. You can double-click on any field to enlarge the process model, get more information or run the comparing-footprint-algorithm or the token replay. Contributing to the project. The Process Cube Explorer was developed as a research-framework and is very easy to extend. process-aware analytics for both historical and live events. The BPI architecture supports plugging in di erent process mining algorithms, such as the alpha and heuristic mining algorithms in the ProM process mining tool . Process mining Process mining aims to extract a business process model from a set of execution logs [1,26,23,4,13,17,25].
Abstract: To discover process models from event logs has recently aroused many researcherspsila interest in the area of process mining. Notwithstanding the interest and related efforts, existing algorithms are far from being satisfactory.
