The rest of the monograph is organized as follows: The authors first propose a framework for A/V data-based research in the business domain and discuss how A/V data analytics can be used to support business decision making in various contexts. They then provide an overview of the key techniques and tools used in A/V data analytics and discuss the procedures and key methodological questions.
