Conclusion
Abstract
The past decade has witnessed the rapid popularity of multimedia genera-
tion and consuming via social media, which features in diversity, heterogeneity, and
interconnection. These unique characteristics have posed challenges to social mul-
timedia computing and applications. In this topic, we have introduced our research
on social multimedia computing from the user-centric perspective. It involves with
three basic tasks of user-perceptive multimedia content understanding, user model-
ing on social multimedia activity, and personalized multimedia services. Moreover,
as extensions of social multimedia computing in the big data era, we introduce the
research topic of cross-network social multimedia computing. A general framework
based on the overlapped users is presented for solutions.
6.1 Promising Topics
To exploit the user-centric characteristics of social multimedia, we have conducted
exploratory work in user-centric social multimedia computing. As discussed in
cation potentials. Challenges as well as opportunities remain in both methodology
innovation and practical application development.
Based on the methodological discussions, and the experimental comparison with
relatedwork, we foresee several research lines in the future work of social multimedia
computing.
Social multimedia knowledge base construction.
Social multimedia involves with
rich multimedia information and complicated user and community social informa-
tion. To pursue in-depth social mining and semantic understanding, especially in
the era of big data, it is of particular significance to construct a comprehensive and
efficient social multimedia knowledge base.
Heterogeneous activity integration.
On the one hand, social media users interact
with each other, e.g., adding friends, joining in interest groups, and with multimedia
content, e.g., sharing, annotation, commenting. On the other hand, users' activities
are distributed on various social media networks, e.g., acquiring news via Twit-
ter, sharing videos via YouTube, and chatting with friends via Facebook. How to
