From big data to big knowledge: HACE + BigKE

Big data deals with heterogeneous and autonomous multi-sources, and aims at mining complex and evolving relationships among data. With the fast development of data collection, data storage and networking technologies, big data analytics has become a hot topic for research and development in various fields. This paper starts with the essential characteristics of big data, reviews existing popular models for big data, including 5V, 5R, 4P and the HACE theorem. Also, from the viewpoint of knowledge modeling, this paper introduces BigKE, a big data knowledge engineering model for big knowldedge, and discusses the challenges and opportunities of big knowledge research and development.
