  The evolution of AI-based system and applications had pervaded everyday life
to make decisions that have momentous impact on individuals and society. With
the staggering growth of online data, often termed as the Online Infosphere it
has become paramount to monitor the infosphere to ensure social good as the
AI-based decisions are severely dependent on it. The goal of this survey is to
provide a comprehensive review of some of the most important research areas
related to infosphere, focusing on the technical challenges and potential
solutions. The survey also outlines some of the important future directions. We
begin by discussions focused on the collaborative systems that have emerged
within the infosphere with a special thrust on Wikipedia. In the follow up we
demonstrate how the infosphere has been instrumental in the growth of
scientific citations and collaborations thus fueling interdisciplinary
research. Finally, we illustrate the issues related to the governance of the
infosphere such as the tackling of the (a) rising hateful and abusive behavior
and (b) bias and discrimination in different online platforms and news
reporting.
