Multi-paradigm Process Mining: Retrieving Better Models by Combining Rules and Sequences

Abstract

Abstract. Business process mining is a well-established field of research which focuses on the automatic retrieval and analysis of process flows. The discovery and representation of these models is based on techniques that come in all shapes and forms. Most notably, procedurally-based algorithms such as Heuristics Miner have been used successfully for this purpose. Also, declarative process model miners have been proposed, which give other insights into the model by generating rules that apply on the activities. This paper proposes an integrated approach to combining these paradigms to discover process models that contain best of both worlds to enrich insights into the event logs under scrutiny.

Declarative Process Modeling in BPMN

“…The notion of transition enablement is extended to handle declarative links between transitions. Meanwhile, [10,6] combine imperative and declarative styles in the context of automated discovery of process models from event logs. Specifically, the approach in [10] discovers hierarchical models with sub-processes that can be either imperative (Petri nets) or declarative (Declare constraints).…”

“…Specifically, the approach in [10] discovers hierarchical models with sub-processes that can be either imperative (Petri nets) or declarative (Declare constraints). Meanwhile, the method in [6] discovers a process model with two types of arcs: imperative (sequence flows) and declarative (Declare constraints).…”

“…More recently, it has been recognized that the boundary between imperative and declarative process modeling is not crisp. Instead, mixtures of declarative and imperative modeling styles are sometimes preferable, leading to proposals for hybrid process modeling notations [21,6]. These developments raise the question of whether completely new notations are needed to support hybrid process modeling.…”

Modelling emergency response process using case management model and notation

“…Declarative activity-centric approach is proposed to enhance the flexibility of the traditional workflow management systems in supporting the loosely-structured processes such as DECLARE [28,29] and DCR Graphs [30][31][32]. The researchers of [33,34] proposed hybrid process modelling; i.e. combining some of imperative and declarative activity-centric approaches.…”

Fusion Miner: Process discovery for mixed-paradigm models

“…In line with this metaphor, this paper presents an approach based on the principles of the authors' work in [7] for combining procedural model fragments and declarative constraints in one map. As such, a new way of mining and representing process models is proposed.…”
