The Social Web is part of the transformations that have redefined the way people relate, use and are affected by technology.

Such systems present challenges to the organization, retrieval and presentation of information, as well as those related to infrastructure and media.

Topics of interest include, but are not limited to:

•	Methods of design and evaluation of social software; •	Factors, characteristics and measurements of success in social software; •	Organizational factors in social software; •	Theories and mechanisms for encouraging participation and collaboration among users; •	Culture aspects and appropriation, emotional and affectiveness in social software; •	Communication, collaboration, sharing and security in social software; •	Identity, privacy, trust and reputation in social software; •	Usability and accessibility of social software; •	Memory and ownership in social software; •	Utilization of social knowledge.
