Process Querying 2016 (to be held in conjunction with BPM 2016)

The International Workshop on Process Querying 2016 (PQ 2016) is the first edition of a workshop for researchers and practitioners in the area of process querying of large process model collections to be held in conjunction with BPM 2016. It aims to provide a high quality forum for researchers and practitioners to exchange research findings and ideas on process querying technologies and practices. Process querying addresses the problem of automatically managing individual process models and collections thereof. Process querying research spans a range of topics from theoretical studies of algorithms and the limits of computability of process querying techniques to practical issues of implementing process querying technologies in software. Process querying reuses existing methods and contributes new results in research areas of business process management, analysis and design of information systems, model checking, formal methods, process mining, conformance checking, process model repair, information retrieval, big data, formal languages, programming languages, as well as other disciplines that study techniques that can be used to address the problem of information overload in process models and/or modern process model repositories.

TUTORIAL: Process Querying with Uncertainty
Avigdor Gal Speaker: Associate Professor Avigdor Gal of the Faculty of Industrial Engineering & Management at the Technion is a Technion graduate and an expert on information systems. His research focuses on effective methods of integrating data from multiple and diverse sources, which affect the way businesses and consumers seek information over the Internet. His current work zeroes in on schema matching — the task of providing communication between databases, and connecting such communication to real-world concepts. Another line of research involves the identification of complex events such as flu epidemics, biological attacks, and breaches in computer security, and its application to disaster and crisis management. He has applied his research to European and American projects in government, eHealth, and the integration of business documents. Prof. Gal has published more than 100 papers in leading professional journals, conferences, and books. He authored the book Uncertain schema Matching in 2011.

Abstract: This talk will focus on aspects of uncertainty when querying process repositories to offer, for instance, re-use driven modelling support, harmonisation of model variants, and model-based system validation. Many of these techniques share reliance on the identification of correspondences between the entities of different models, also termed process matching. Taking up recent advances in matching process models in particular, we shall provide an overview of concepts and matching techniques in this domain. The talk will include a brief review of similarity measures for the textual, structural, and behavioural dimensions of process models, which form the basis of matching techniques. The talk will then present a vision of using uncertainty management tools to support effective querying of process repositories.


The main topics relevant to the PQ workshop include, but are not limited to:

  • Behavioral and structural methods for process querying
  • Imperative and declarative process querying
  • Exact and approximate process querying
  • Expressiveness of process querying
  • Decidability and complexity of process querying
  • Process query languages and notations
  • Indexing for fast process querying
  • Empirical evaluation and validation of process querying
  • Label management in process querying
  • Information retrieval methods in process querying
  • Process querying of big (process) data
  • Automatic management of process models, e.g., process model repair
  • Automatic management of process model collections
  • Event log querying
  • Process performance querying
  • Multi-perspective process querying, e.g., resource, data, etc.
  • Process querying and rich ontology annotations
  • Applications of process querying, e.g., process compliance, standardization, reuse, etc.
  • Experience reports from implementations of process querying tools
  • Case studies in process querying

Prospective authors are invited to submit papers for presentation in any of the areas listed above. The paper selection will be based upon the relevance of a paper to the main topics as well as upon its quality and potential to generate relevant discussion. Authors are requested to prepare submissions according to the format of the Lecture Notes in Business Information Processing (LNBIP) series by Springer ( Submissions must be in English and must not exceed 12 pages (including figures, bibliography and appendices). Each paper should contain a short abstract, clarifying the relation of the paper with the main topics (preferably using the list of topics above), clearly state the problem being addressed, the goal of the work, the results achieved, and the relation to other work. Papers should be submitted electronically as a self-contained PDF file via the PQ 2016 submission system ( Submissions must be original contributions that have not been published previously, nor already submitted to other conferences or journals in parallel with this workshop.


All workshop papers will be published by Springer as a post-workshop proceedings volume in the series Lecture Notes in Business Information Processing (LNBIP). These proceedings will be made available to all registered participants approximately four months after the workshop, while preliminary proceedings will be distributed during the workshop. For each accepted paper, at least one author must register for the workshop and present the paper.
