The challenge of managing unstructured data represents perhaps the largest
data management opportunity for our community since managing relational data.

to other players, ranging from communities such as AI, KDD, IR, Web, and
Semantic Web, to industrial players such as Google, Yahoo, and Microsoft. In
this essay we explore what we can do to improve upon this situation. Drawing on
the lessons learned while managing relational data, we outline a structured
approach to managing unstructured data.
