The Web 2.0 was a milestone in the development of new software applications for the Web. The collaboration, communication and interactivity among users happen nowadays in a way never seen before. With richer and more interactive and innovative applications, we have noticed the emergence of technologies such as social categorization (e.g. tagging/folksonomies), social networking, navigation and social search, collaborative publishing and sharing, etc. These technologies enabled a paradigm shift: more than linking documents, pages or resources, the Web now connect people, organizations and concepts, creating a Social Web.

The success and usefulness of these technologies (the social software systems) directly rely on their users and, consequently, on the aspects related to the user experience, such as emotional and socio-technical factors, including how the interface was designed. Therefore, it is urgent to discuss these concepts considering the human values of our mutable society in which: the users are not only consumers but also creators of content; the technology should allow a creative involvement and consider the emotional aspects of the user experience; and the sharing via Web can happen anytime, anywhere and from computer systems embedded in various objects.

The second edition of the Workshop on Aspects of Human-Computer Interaction for the Social Web (WAIHCWS) aims to promote discussions about the opportunities and challenges that the Social Web brings to the human-computer interaction research community, focusing on the concepts of sociability (e.g. communication, collaboration, sharing, social norms, etc.) and human values (e.g. privacy, reputation, trust, autonomy, etc.). These challenges require methods, techniques and tools for the design and evaluation of interactive systems that effectively deal with these values in the aspects of human-computer interaction.

Further information, including the II WAIHCWS topics of interest can be found at the Call for Papers.

Besides the presentation of selected articles, II WAIHCWS agenda includes discussions among participants. We hope the discussions support the sharing of knowledge and encourage the arrangement of research partnerships.
