Object-centric processes from A to Z

2nd International Workshop (co-located with BPM 2024)
Krakow, Poland 

About

Traditionally, processes are modelled and discovered primarily considering their control-flow dimension, while disregarding other key dimensions that affect the control flow, such as the data dimension. Consequently, the resulting models are unable to suitably represent real-life, widespread processes where behaviour arises from the complex interplay among multiple business objects and their one-to-many/many-to-many relationships. ​New paradigms that combine data and processes, such as object-centric processes, present new perspectives to the field of business process management, but also bring new challenges. 

On the one hand, object-centric processes toned to be correctly specified and modelled. Such multi-perspective models are intrinsically difficult to analyse. This calls for a suitable trade-off between expressiveness and feasibility of analytic techniques. In addition, object-centric models can span a complex network containing many processes and objects. Thus, they bring great potential to create models that cross process and organisational boundaries that current modelling techniques impose. 

On the other hand, process mining focus on the discovery and analysis of object-centric models from event data, which poses a twofold challenge. First, the current notion of event logs fail in representing event data for object-centric processes. Conventional event logs contain isolated traces, whereas object-centric processes require richer, relational and graph-structured representations of the event data. Second, novel process mining techniques and suitable event data/log formats have to be studied so as to operate over such complex data and fully unleash the insights hidden therein. This also brings the need to ensure that modelling constructs in object-centric process notations can be effectively and efficiently discovered and analysed. 

The main objective of this workshop is to bring together researchers from the fields of BPM and PM who work on object-centric process to share their ideas and current research and to discuss challenges and future directions of the field. 

Topics

Topics of interest include, but are not limited to:

  • object-centric process modelling (formal and conceptual foundations, best practices etc)
  • extensions of object-centric formalisms
  • syntactic and semantic properties, correctness criteria
  • object-centric process composition
  • collaborating object-centric processes
  • formal techniques for object-centric process analysis
  • object-centric event log formats
  • data preparation for object-centric log extraction
  • discovery, conformance checking and monitoring
  • conceptual foundations of object-centric process representation
  • object-awareness vs. object-centricity
  • experience reports on teaching object-centric processes
  • insightful surveys and case studies on adoption and application of object-centric approaches  
  • visionary papers 

Submission and publication

There are two submission categories:

  • Full papers — 12 pages (including references), focusing on complete or ongoing research, case studies or tool/system descriptions.
  • Short papers — 6 pages (including references), suitable for visionary and position papers as well as extended abstracts for PhD students in which they can present their ongoing research. 

To diversify the workshop program, we offer space for a limited number of short tutorials. Each tutorial should provide an in-depth account on techniques, tools and resources (such as logs and use cases) in the area of object-centric processes. All the materials related to the tutorials will be published on the workshop’s webpage. The 1-page descriptions will be included as abstracts in the workshop proceedings.
Each tutorial proposal must contain the following information:

  • Title;
  • Presenter’s name, affiliation and their short bio;
  • 1-page tutorial description (including references), highlighting why it is relevant to the OBJECTS workshop, planned activities to engage the audience and what are the key learning objectives.

Submission (both papers and tutorial proposals) will be via EasyChair. Authors are requested to prepare their submissions according to the Springer’s LNBIP format. Papers have to be written in English, and all the papers written in different formats and/or exceeding the above specified page limits will be desk rejected. When submitting, select "Object-centric processes from A to Z” as the submission track.  

Each submission will receive at least three reviews. If a paper gets accepted, at least one of the authors must attend the workshop to present their work. 

Special issue

Authors of the high voted papers will be invited to submit their extended works to a special issue in the TBD journal.
