This paper aims to argue the feasibility of measuring the international outputs of Chinese social sciences by SSCI, and empirically points out the deviation in the coverage and categories of the database to reveal the problems overlooked in the process of using SSCI. Although questioned for the type diversity and localization in language and challenged by emerging databases, SSCI is also an ideal database to represent the international outputs in Chinese so?cial sciences. The paper also confirms the recording deviations from the both perspectives of the whole database and high cited papers. There are cognitive differences and categories cross in the WC disciplinary classification, although it is a unique advantage of SSCI database. Using the SSCI database, which is an ideal tool in the bibilometrics on the so?cial sciences, we should pay more attentions to the source journals and specially carry on the research on disciplinary level by documents clustering methods.

The paper first overviews the current state of danmaku studies at home and abroad on the basis of danmaku systems and sub-culture indicating the ACG group. Doupao is used as a case to conduct an empirical study on the as?sessment of information architecture of danmaku video website. A formal analytical hierarchy process method com?bined with focus group and in-depth interview are employed to examine the various dimensions of IA, including infor?mation organizing, information labeling, information navigation, and information retrieval.
From the perspective of multi-layer network, a two-layer social network including online and offline net?works is presented to study the emergence of collective behavior. Drawing on theories of communication and social psy?chology, the formation and evolution of collective behavior under the interaction of online-offline social network is theo?retical investigated. Moreover, the authors develop a dynamic model of collective behavior and validate it by experimen?
tal simulation. The results show that: opinion exchange between individuals will promote the emergence of collective be?havior; online and offline interactions can be prone to make collective behavior emerge; the social decision of individu?als can apparently impact collective behaviors on online-offline social networks. We can find that the results well sup?port the reality. Our work is from a new perspective and based on a novel sociology method to study collective behaviors and provide practitioners with theoretical and practical implications to handle various collective behaviors.

This paper investigates the basic data of Changjiang Scholars in four ASNS: ResearchGate, Mendeley, Aca?demia and SoScholar. The survey results show that the Changjiang Scholars have not registered more than 50% of the ASNS, indicating that the overall usage is not satisfactory. Meanwhile, Changjiang Scholars' continuous use of ASNS re?mains to be improved with the exception of ResearchGate. The results also show that, compared to other academic so?cial networks, ResearchGate provide Changjiang scholars with a higher degree of presence. Disciplinary differences al?so exist, scholars from science, engineering and medicine disciplinary are more active than scholars from the humani?ties and social sciences.
