Hello Mr. Harrill,
Our colleagues in Sheffield are correct that we have experience in
solving such problems. However, there is no standard component that can
solve such disambiguation, because the task may have various definitions.
A task where we have "Paris, France" in the text and we want to match it
with Paris in an ontology like DBPedia, is doable in GATE using the IdRF
framework from Ontotext. By "match" I mean to assign to this Paris the
correct DBPedia URI. If you are trying to solve that simple, but not
trivial task, Ontotext can provide documentation and, if needed,
services for using IdRF in GATE.
The second, more general, case is when "Paris" is mentioned in the same
document with names like "France" or "Nicolas Sarkozy" which point to a
specific unambiguous location, but they are not used next to "Paris". We
have expertise in this area, but we have only developed domain-specific
solutions, like disambiguating protein abbreviations in the biomedical
domain. See [1] for an example for a possible approach. Note that the
spreading activation mentioned by that research paper is supported by
our BigOWLIM database. We will be happy to provide services for
developing a GATE component based on that or similar approach for named
entity disambiguation.
Best regards,
Anton Andreev

To whom it may concern,
I have been researching methods at which to perform disambiguation for
Location Entities within GATE. As an example, I am searching for a
method to differentiate Paris, France from Paris, Virginia. I spoke
with one of the GATE developers who stated that Ontotext has
successfully performed this task within KIM. Is there any information
that you can provide me in order to perform disambiguation within
GATE. Additionally, is KIM performing this function within an
ontology? I would appreciate any information you could provide in
regard to this matter.
Thanks,
Dave
