Panagiotis G. Ipeirotis, Alexandros Ntoulas, Junghoo Cho, Luis Gravano
2007 ACM Transactions on Database Systems  
Then, we show how to use "survival analysis" techniques in general, and Cox's proportional hazards regression in particular, to model database changes over time and predict when we should update each Article  ...  Large amounts of (often valuable) information are stored in web-accessible text databases. "Metasearchers" provide unified interfaces to query multiple such databases at once.  ...  Next, we describe how we use the Cox regression model to represent changes in text database content summaries.  ...
