[BizInsight@HKUST - Lunch Presentation Series] The Dark Side of Big Data and Online Social Networking

Big data and online social communities have been integrated into our daily lives. With information so readily available, it is essential to manage them well to avoid potential pitfalls. Professor Michael ZHANG and Professor Hong XU of the Department of Information Systems, Business Statistics and Operations Management will share their findings and thoughts in managing online data and social communities.

Big Data Pitfalls
While big data is playing an increasingly more important role in organizational decision making, there are certain pitfalls that managers and data scientists should avoid.

In his talk, Professor Michael ZHANG will go over some potential pitfalls that people face when they do big data analytics.

Peer-Disclosure in Online Social Communities
A novel facet of privacy concern has emerged due to peer disclosure of sensitive personal information in online social communities. When online users post about their “friends” or even “non-friends”, their behavior impose a negative externality on other people.

Professor Hong XU will talk about the use of game theory to analyze interactions among users in social communities. The model encompasses the benefit from posting information, positive externalities such as recognition and entertainment benefits due to others’ sharing of information, and heterogeneous privacy preferences. She will also discuss two policy instruments--nudging and quota--and a combination of the two.
