[Kim-discussion] GATE_LOCATION_DISAMBIGUATION

[Anton Andreev]

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
