Hi Dileepa,
Are you using only OpenNLP NER engine or are you also including an
Entity Linking engine?

How can we improve the accuracy of these results?

Subject: How to refinin NER results in Stanbol
To: Stanbol Dev List <dev@stanbol.apache.org>
Hi All,
I have been running some load tests on Stanbol entity recognition, with a
high load of content extracted from web articles and stored in a Solr index.
My objective is to achieve an efficient and accurate enhancement result
for the content submitted.
But I think some of the NER results obtained are not accurate.
For an example I submit the content :
Group Finance Director Chris Lucas and Group General Counsel Mark Harding
to retire from Barclays
I get below entity recognition results from default enhancement-chain;
People : Chris Lucas, Mark Harding
Organization: Barclays, *BT Group*, *Finance Director Chris Lucas and
Group General Counsel*
The highlighted NERs for organizations above are inaccurate results.
BT Group is not mentioned in the content, and the result : *Finance
Director Chris Lucas and Group General Counsel * is not an organization,
rather a phrase.
Further if I add a fullstop (.) to the end of the sentence "Barclays" is
not recognized as an Organization.
I think we need to improve these results in Stanbol NER. Can we tweak
OpenNLP-NER component for this?
Any ideas/pointers on how to refine these enhancement results will be
immensely helpful.
I'm looking for a way to improve the accuracy of the results as much as
possible.
Thanks,
Dileepa
