Business Process Graphs: Similarity Search and Matching

Organizations create collections of hundreds or even thousands of business process models to describe their operations. This chapter explains how graphs can be used as underlying formalism to develop techniques for managing such collections. To this end it defines the business process graph formalism. On this formalism it defines techniques for determining similarity of business process graphs. Such techniques can be used to quickly search through a collection of business process graphs to find the graph that is most relevant to a given query. These techniques can be used by tool builders that develop tools for managing large collections of business process models. The aim of the chapter is to provide an overview of the research area of using graphs to do similarity search and matching of business processes.
