A paper on metadata use by the federal government "Hydra-headed Metadata" by Jamie Callan, W. Bruce Croft and Eduard Hovy
Recently, the Digital Government program of the National Science Foundation has funded a number of projects to address the challenge of integrating large, heterogeneous, widely distributed and disparate Government data collections. In this paper, we describe two complementary approaches: large ontology-based data access planning using small domain models semi-automatically acquired, and dynamic metadata creation from language.
