We are delighted to present this special issue of World Wide Web on Data Science in Cyberspace 2019. As we know, the world is increasingly becoming a digital space. Especially in recent years, there is a huge growth of data in the field of cyberspace, including e-commerce, Internet of Things, online social media, and many other Internet services. People and organizations are facing zettabytes of structured and unstructured digital big data every day. This growth poses great challenges to traditional data management, data mining, and machine learning paradigms. Data Science, as a highly interdisciplinary field, is playing a more and more critical and central role in the development of cyberspace and various applications. It involves obtaining meaningful insights from big data which is processed through analytical, machine learning, and other state-of-the-art intelligent skills. The special issue was preceded by the 5th IEEE International Conference on Data Science in Cyberspace (IEEE DSC), held at Hangzhou White Horse Lake Jianguo Hotel (June 23-25, 2019 in Hangzhou, China). The articles have undergone rigorous peer-review according to the conference's high standards. Selected high quality papers were invited to submit an extended version to this special issue by adding at least 40% new materials for journal publication.
