讲座主题

Measuring Time Information in Digital Data

 

 

Abstract:


Time is the single common denominator across all types of digital data from the internet, mobile networks, and IoT (internet of things).  However, the rich information embedded in the time stamps of digital data has often been taken for granted.  As such, this gold wine has remained to be fully exploited.  Conceptually, there is lack of well-developed social science theory to guide how to mine time information.


Operationally, there exista wide range of difficulties and challenges to be solved.  In the talk, I’ll illustrate a particular challenge – how to choose the measurement unit of time – as time can be quantified by a fixed-interval unit (e.g., hourly, daily, etc.), avariable-interval unit (e.g., time segments, clusters of segments, etc.), afrequency-domain unit (e.g., cycles), and so on. 


What is the “right” unit and why?  I’ll present our approach and discuss the relevant merits and shortcomings involved.
