The LDC ACE toolkit may also satisfy your needs:


It is highly customized to ACE annotation, but can be modified
via an XML config file to suit a number of similar needs --
including NE annotation, with co-reference. We find this tool
to be easier to use (at scale for raw, untagged data) than either
Callisto or Wordfreak, but I am not familiar with gate.

Also, the output is .ag.xml format. But the package includes
conversion scripts to the latest ACE Pilot Format (.apf.xml).
These would need to be modified to the new tagset, but would
work nonetheless. If you're interested in the infrastructure,
I have a few perl script that generate a tabular output as
