In this paper we provide high-level architecture of Document Analysis & Change detection system responsible for regulation retrieval, document analysis and preparation for linkage to business processes. The goal of the research is to describe approach to transform regulation in the form with annotated structural parts such as chapters, sections, articles, and subarticles that facilitates business process linkage to the specific structural part of relevant regulation, and link these structural parts to the business process. In this paper we also propose approach for business process and regulations change management. By applying the approach of regulation change management we could ensure regulation change monitoring and thus facilitate up-to-date business process compliance with regulations.
