Lab members Jonathan Zhu and Xiaofan Liu, along with Dr. Tetsuro Kobayashi of Department of Media & Communication, were invited to give talks at the First International Workshop on Computational Humanities and Social Science at Tohoku University, Sendai, Japan on 19 January 2020. Tohoku University, one of the seven leading national universities in Japan, has recently established a Division on Computational Humanities and Social Science, the first of its kind in the country, to gear up its cutting-edge research and doctoral student training in the emerging area. Nine speakers, including academic scholars and industry researchers from Japan, Hong Kong, and the Netherlands, presented their latest research on computational social science.

Jonathan introduced some of new methods his group was developing for measuring mobile use sessions and analyzing mobile application sequences. Dr. Kobayashi reported the methods and findings from his collaboration project that used deep learning algorithms to detect politician’s faces from television news. Xiaofan presented the results from his recent scientometric study of communication journal publications. The speeches attracted interests from the audience as they demonstrated the wide range of topics and the advanced level of computational methods in the faculty research at CityU.

After the conference, the CityU visitors held a meeting with Dr. Hiroki Takikawa, Director of Division of Computational Humanities and Social Science at Tohoku University, to discuss further collaborations in research projects, student exchanges, and other areas.

The article, entitled “The virality and growth of cascades” has been accepted as an oral presentation at NetSci-X 2020, Tokyo. Two members of the Web Mining Lab, Mr. Yafei Zhang and Prof. Jonathan Zhu, participated in this study.

In this work, they proposed a novel approach to characterize the virality of cascades and introduced a more realistic model to mimic the growth of cascades. This work is an output of collaboration with a team of scientists from control science and engineering at Shanghai Jiao Tong University.

Mr. Yafei Zhang is now a joint PhD student co-supervised by Prof. Jonathan Zhu at City University of Hong Kong and Prof. Xiaofan Wang at Shanghai Jiao Tong University.

NetSci-X, the Network Science Society‘s signature winter conference, aims to foster interdisciplinary communication and collaboration in network science research across computer and information sciences, physics, mathematics, life sciences, social sciences, arts and design. The coming NetSci-X conference will be held in Tokyo, Japan from January 20 to 23, 2020.

Jonathan Zhu paid an intensive visit to Peking University HSBC Business School (PHBS) on Sept 25, 2019, where he met half a dozen senior and junior faculty members individually, each for half-hour long, and gave a seminar talk to faculty and graduate students on “Computational approaches to communication research: theory, methods, and applications”.

Located in Shenzhen University Zone, PHBS houses a body of highly international faculty and students, with all teaching and learning conducted in English.  It also runs an overseas campus in Oxford, which is likely to be the first of the kind in China. Of the graduate programs is an MA in Financial Journalism, whose faculty members and students working on a range of topics overlapped with those of Web Mining Lab.

“Two members of our Lab graduated from your program, and we used to work with Dr. Kai Lei and his ICNLab of School of Electronic and Computer Engineering on your campus,” said Jonathan at the beginning of his talk, “the visit today opens a new channel and a new direction of collaborations between us”.  In addition to computational communication research, Web Mining Lab’s mapping studies of SSCI publications have also attracted keen interests from PHBS scholars.

The 8th Chinese National Conference on Social Media Processing was held in Shenzhen, China on August 16~18. Several lab members played active roles in a Computational Communication Research Panel.
Lun Zhang (an associate professor at Beijing Normal University) hosted the division. Xiaofan Liu gave a talk on “the Fragmentation and Centralization of Communication Research”.
Hai Liang (an assistant professor at Chinese University of Hong Kong) gave a speech about the social contagion during the information diffusion process.

The article, entitled “Who is tracking health on mobile devices: A behavioral logfile analysis in Hong Kong”, has been published on JMIR mHealth and uHealth by Lu Guan, Tai-quan Peng, and Jonathan Zhu. In their article, they analyzed users’ mHealth app activities from a representative panel of about 2500 users in Hong Kong. Their findings suggest the use of mHealth apps demonstrates a significant temporal pattern and such temporal pattern is moderated by individuals’ demographic characteristics.
