Hi again,
I've been looking the Dbpedia and DBLP examples, but actually i need to
define my own ontology with customised relations (not based in definitions
of Dbpedia). I didn't explain my problem very well. I need to extract tags
from plain text, yes, but i need to make inferences over my domain
(enterprise terms and concepts that are only used in a closed environment).
What kind of inference? Please give an example of sample input and
expected output.
Input -> PTS is a component of a product for cleaning mowers.
Inference -> PTS is a product for gardening (i defined this in a
hierarchical ontology, superclass).
These classes are too specific for Dbpedia (maybe bad example?) and
you can imagine what difficult would be to government documents (with
its particular idiosyncrasy).
Is there any way to upload my ontology previously defined in Protégé with
mimetype rdf+xml? I thought that when i uploaded the owl file to a specific
scope in ontonet, i could configure Stanbol to use this ontology.
What do you mean by "use"?
I want that Stanbol "forgets" another source. I need that, in the
plain text, Apache Stanbol choose tags only defined in my ontology.
Example:
I have a PTS but i don't have garden.
Result:
PTS->Component_for_mowers->Component_for_gardening
Apache Stanbol don't extract "garden" because it isn't defined like an
entity (class) in my owl file or my own ontology.
I've
already created this ontology. If it's not possible, what are the steps i
need to follow in Apache Stanbol to define own entities that Natural
Language Processing Engine can extract from plain text? And then, when these
own entities has been extracted, how can i connect these entities with my
relations?
What do you mean by "connecting entities with relations"?
Relation:
Maybe_must_buy: Gardener->Component_for_gardening
Example:
I have a PTS. Peter is a gardener.
Result:
PTS->Component_for_cleaning_mowers->Component_for_gardening
Peter->Gardener
Peter Maybe_must_buy PTS
Sorry for the example :). I expect you understand what i want to say.
Best regards.
