Topic status: We're looking for students to study this topic.

Process querying studies automated techniques for managing large collections of models of process-aware information systems based on process instances that these models describe. A user interacts with a collection of process models via process querying intents. A process querying intent is a formally specified request to manage a collection of process models for a particular purpose. Process querying research initiative spans a wide range of topics from theoretical studies of algorithms and the limits of computability of process querying techniques to the practical issues of implementing process querying technologies in software.

The study of process querying techniques is an integral part of our broader research program on design of automated methods for management of process knowledge within organisations.

Current research interests in process model repair include:

  • decidability and complexity of process querying
  • design of process query languages
  • empirical studies on process querying
  • design of index data structures for fast process querying
  • explanation and visualization of process querying results.
