Indexing Process Model Flow Dependencies for Similarity Search
Résumé
The importance gained by process models in modern information systems leaded to the proliferation of process model repositories. Retrieving process models within such repositories is a critical functionality. Recent works propose metrics that rank process models of a repository according to their similarity to a given query. However, these methods sequentially browse all the processes of the repository and compare each one against the query, which is computationally expensive. This paper presents a technique for quickly retrieving process models similar to a given query that relies on an index built on behavioral characteristics of process models.
