RE: How to find a proper ontology for my classes and properties?

Hey Yury,

You may also want to try Falcons Ontology Search:
http://ws.nju.edu.cn/falcons/ontologysearch/result.jsp?query=has+Owner

or Falcons Concept Search:
http://ws.nju.edu.cn/falcons/conceptsearch/result.jsp?query=has+Owner

Cheers,
Gong

property 'hasOwner'. I understand that it's much better to use this property
from one of the existing ontologies rather than use property from my own
namespace.

I wonder if there is something better that fulltext search.

first to get a first impression about the dataset? At the moment I first
make some SPARQL queries to this dataset, such as:

come up with a opinion where I need data from the dataset or not.

datasets?
