General Stanbol questions
Hi,
As I am trying to get my hands around stanbol, I have couple general design
questions.
*1. Enhancement Chain firing and results*
How to find out which enhancement chain detected which entities? One way, I
could see that by adding/removing particular chain. Is it possible to just
enable it via logging within current code?
For ex.
I have a chain categorized-linking and would like to find out whether this
chain fired and labeled entities properly
*2. Categorize entities differently*
Is it possible to categorize your detected entities as something else?
i.e. other than People, Organizations or Places
What steps one need to take in current framework to achieve the same?
*3. Domain specific modeling*
Suppose, I have a small domain and various types of entities. I am
interested in
a. analyzing various entities
b. linking them with other entities and find relations from dbpedia/freebase
c. infer interesting aspects using reasoning
Is Stanbol the way to go or Marmotta? or Is it preferred to develop a
custom engine using Stanbol which uses internal components to perform all
of the above tasks?
*4. Enhance detected entities by annotation*
Suppose, opennlp-ner detected an entity xyz. If I want to annotate this
entity with additional attributes/fields using different custom
vocabularies, what are the dev. steps I need to take?
*5. Previous demo project(s)*
At the same time, any luck with restoring demo project(s) within 0.12
branch ? I believe, it demonstrates various aspects and it would be great
to have it restored.
Thanks in advance,
Rajan

Those are the Open NLP models for Named Entity Extraction.

Hi Rupert,
Thanks again for detailed answer.
I could setup the demo and look at the results. It's extremely powerful.
One quick question, what's the purpose of these bin files under resources
directory.
bionlp2004-DNA-en.bin
bionlp2004-RNA-en.bin
bionlp2004-cell_line-en.bin
bionlp2004-cell_type-en.bin
bionlp2004-protein-en.bin
With best regards,
Rajan

Hi Rajan,
The demo never included any Java code.
The module just provides configurations [1] and datafiles [2]. Those
will be installed with the bundle using the Sling Installer and
Stanbol DataFileProvider infrastructure when the bundle is installed.
Note the <Install-Path> and <Data-Files> instructions configured for
the maven-bundle-plugin in the pom.xml file.
The demo also provides a shell script [3] the indexes eHealth related
datasets and of corse the README explaining the demo

Hi Rupert,
Thanks a lot for the detailed answers. Let me play a little bit further before I ask additional follow-up questions.
As far as demo is concerned, I am interested in eHealth demo as it covers lots of items from my questions. At present, the Java code for it is missing. Is it possible to restore Java code for eHealth demo in 0.12 branch?
With best regards,
Rajan

A enhancement chain has 1..* enhancement engines. The engines create
the annotations not the chain. So your question should be what engine
is creating an annotation. This information is provided by the
dc:creator and dc:contributor metadata of the enhancement. See also
the documentation at [1]

You can use the Custom NER Model Extraction Engine [2].
The models used in the documentation of this engine can be found at [3]

* Entity linking to your custom vocabulary in Stanbol
* If you want to have your custom entities linked with
dbpedia/freebase it is better to do that in the vocabulary. I think
Google refine provided reconciliation to freebase. that could be
definitely an option.
* If you want to find additional entities contained in
freebase/dbpedia configuring an other entity linking in Stanbol makes
complete sense.
Not sure what you mean with "infer interesting aspects using reasoning".

If you just want to link Named Entities with a controlled vocabulary
you can use the FST linking engine [4] with the Linking Mode set to
NER (read the Linking Mode of the engines documentation). In short you
will want to configure a "Apache Stanbol Enhancer Engine: FST Linking:
Named Entities" for the vocabulary you want to link against.

I hope those are still functional in the 0.12 branch. No immediate
plans to move them to 1.0.0 (mainly because of lack of time).
Contributions are very welcome.
Hope this helps
