Bob, i have downloaded and have been experimenting with LingPipe
1.0.7 and i think i have run into a bug.

if i take the demo bat file that processes a directory and add -
elements= to tag some of my XML documents only within some of my
specific elements, it no longer does named entity tagging. instead,
all it does is sentence boundary detection within the tags that i
named (i.e. <sent> tags are produced but no ENAMEX tags).

BTW, you would make my life a lot easier if you preserved XML
namespace specifications.

Herb...
