[Corpora-List] annotation tools

[Alberto Lavelli]

Dear CORPORA list members,

I'm interested in graphical tools for manual annotation of texts.  The
goal is to manually annotate documents to train/test IE systems.  In
particular, I'm interested in tools that allow to annotate not only
entities (e.g. Named Entities) but also relations between such
entities (e.g., the relations of the Template Relation task in MUC-7:
employee_of connecting person and organization, or location_of
connecting organization and location).  Tools I'm already aware of:

 - the ALEMBIC Workbench by MITRE (already downloaded; it's the tool
   I'm more familiar with)
 - WordFreak (downloaded a few days ago; one of the problems with
   WordFreak seems to be the shortage of documentation)
 - the ACE annotation tools by LDC

I have had a look at the old messages of the list without being able
to find anything interesting.  I have already consulted the web page
on Linguistic Annotation by Steven Bird and Mark Liberman
(http://www.ldc.upenn.edu/annotation/) but I have found nothing which
appears to be relevant (BTW, the last update was in December 2001).
I'm particularly interested in first-hand experience of use of the
tools (including the ones mentioned above).

I'll post a summary of the replies.


thanks in advance
