Hello,
can anyone suggest alternatives to GATE
(http://gate.ac.uk/download/)? I would like to index place and person
names in PDFs using gazetteers (ie, dictionaries) and normalize dates
( (eg, December 1st, 2001 will be indexed as 20011201) and feed the
indexes to SOLR?
GATE is a great tool, but the search engine, Mimir, is unfortunately
not customizable (well-document enough) enough for my purposes, which
are to return the found documents (PDFs) ordered by document or
entity (eg, {Date}, {Person}) name.
Many thanks.

Hi Phillippe,
For entity extraction we often use the Stanford NLP libraries which are
part of GATE but a lot simpler (GATE is a bit of a beast TBH): for
example in a taxonomy editor/classifier prototype we built recently we
use Stanford to pull out entities from classified documents as
suggestions for improving a node definition:

There's also an interesting European Commission funded project in this
area, a 'marketplace' for text classification & extraction apps:
