Abstract: |
In this talk, I will present
analysis results of email communications in a large-scale enterprise
network. Our study first focuses on understanding the social graph
induced by email communications between individual users. Specifically,
we examine how email communication flows are correlated with user
profiles, the organization structure, and how outside information
penetrates the enterprise. We then concentrate on understanding
the information processing load imposed to users and the strategies
applied by users in email triage. To the best of our knowledge,
this is the first measurement study of email communications of
a global enterprise network comprising email data from over 100,000
employees spread across multiple continents. Our analysis results inform the design of network applications that takes into account typical user behaviour in social interactions and solitary information processing. Our large-scale dataset further allows us to examine the validity of several hypotheses suggested by the social network theory. |
