Summing up …
- Very little difference in the DUC 2001 summaries with respect to quality of the unmarked (peer-only) material
For the future…
- DUC-2001 systems are not producing junk, so little will be unrelated.
- Summary authors are not producing junk, so little will be good enough to replace what is there
- What then if anything can be usefully measured with respect to peer-only material?
