Title:     Extracting Problems for the Future of DBMS Research

Abstract:   Storing, querying, and managing the evolution of extracted  
data sets (that is, structured information “extracted” from text)  
poses an interesting set of challenges for information management  
systems. In particular, the schema may be only partially known,  
chaotic, and constantly evolving; incomplete, inconsistent, and/or  
incorrect data is normal and unavoidable; and users are likely to want  
to query the structure of this data without wanting to learn the  
schema of the data or a structured query language. It turns out that  
far from being unique to extracted data sets, versions of all of these  
problems have long existed, unfortunately largely unsolved, in  
“classical” database applications. However, it is possible that a  
change in perspective about the requirements of their solution may  
allow progress. This talk should be accessible to non-DBMS folks.
