Privacy Issues in Big Data and Privacy-preserving Data Mining

The utilization of big-data is expected to broadly contribute to the innovative services and business models with accurate model of our behaviors. Personal data is considered to be highly values here and hence we have many issues in privacy. This talk introduces a couple of incidents related to personal data in big data business and clarify the risk of re-identification of individual from anonymized data. Current Personal Information Protection Act restricts the exchange of personal data among companies. There is no clear standard to specify procedure for reduction of risk of identification. To address the privacy issues in big data application, the notion of privacy-preserving data mining has been studied well. In this talk, the fundamental principle and some application of privacy-preserving data mining are introduced.

How to Help Researchers Using Prescriptive Analytics and Complex Event Processing?

Explosively increased Big Data and very fast technical evolutions require an entirely new analytics that is able to precisely analyze researchers’ activities until now and to provide research directions from now on. Prescriptive analytics shows fundamental difference with descriptive/predictive analytics in that it should provide multiple strategies to achieve a given research direction. Complex event processing also shows a new way to read implicit intentions from many kinds of activities such as publishing article, travelling on business, and attending conference. Thus, this talk shows a case study by explaining requirements and factors for implementing a personalized research service with InSciTe Advisory, as a data-intensive intelligent service, for helping to find plausible research directions. This talk also covers data gathering, information extraction from entities to simple events, reasoning, and Hadoop ecosystem.

Biography of Hanmin Jung

Hanmin Jung works as the head of the Dept. of Computer Intelligence Research and chief researcher at Korea Institute of Science and Technology Information (KISTI), Korea since 2004. He received his M.S. and Ph.D. degrees in Computer Science and Engineering from POSTECH, Korea in 1994 and 2003.
