Knowledge plays vital role in every stage of learning and research. The academic cloud providing education services to students, teachers and researchers can further be equipped to provide knowledge as a service to the users for their knowledge enhancement and problem solutions. This is feasible through development and embedding of knowledge database and extracting relevant knowledge from the academic cloud system. This paper proposes an architecture that uses a new paradigm KaaS on cloud environment. The architecture takes care of insertion of data, conversion of data into knowledge, knowledge extraction and providing various services.
