Hi Nathan, You are testing the enhancer with a very short sentence and the Language Detection engine is identifying 'no' (probable Norwegian) as the sentence language. By default, Stanbol uses the identified language code for both loading OpenNLP models in that language and for entity lookup for searching only entity labels in that language. There is a couple of things you can do for avoiding an empty annotation is these situations:
1. Force the language code as a header in your request (curl request in this case) 2. Configure English 'en' or whatever language you know your dataset has labels for the entities as Default Matching Language which is missing in your configuration. More information here: https://stanbol.apache.org/docs/trunk/components/enhancer/engines/entitylinking Also, you also would probably like to disable NER engines for such kind of entities. Hope that helps, Rafa On Tue, May 31, 2016 at 6:13 PM Nathan Breit <br...@ecohealthalliance.org> wrote: > Hello, > I am trying to configure the Entityhub linking engine to use an Entityhub > site with vocabulary from the Disease Ontology ( > http://disease-ontology.org/), > but when I enhance text with it, labels from the ontology are not being > annotated in the text.
