Hi,
I have problems with using the Custom NER Model Extraction Engine [1].
Basically, no entities are not found, even though the underlying model is
correct.
Here's what I did:
1. I build a custom NER model for places from geonames.org according to
the OpenNLP website [2]. I tested my model with the OpenNLP command line
tool, and it worked (i.e. I give my model a text and the entities are found
correctly).
2. I copied the model to both ./launchers/stanbol/datafiles/geonames.bin
and ./enhancement-engines/topic/engine/sling/datafiles/geonames.bin.
3. In the Apache Felix Web Console Configuration, I created a new "Custom
NER Model" with the following settings:
- name: Geonames NER
- Name Finder Model: geonames.bin
- Type Mappings: place > http://dbpedia.org/ontology/Place
- Ranking: -100
4. I build a new enhancement chain with: tika, langdetect,
opennlp-sentence, opennlp-token, opennlp-pos, opennlp-ner, geonames-ner,
geonames
5. Server restart
6. I send the exactly same string as in 1. when I tested the model, but no
entities are found.
Any hint would be useful!
How can I check, that Stanbol correctly finds my geonames.bin file? If I
intentionally add a file which does not exist, no error occurs.
Thanks in advance
Stefan
