Question

I want to create ontology for the INSPIRE data.As the there is a large amount of data I wanted to know what technique should be used for that

Answer 1

An ontology should be built as part of a consensus of users with expertise in the domain of interest. The simple advice would be don't build your own, but rather use (and extend if necessary) an existing ontology

For tools to create/manage ontologies, try poolparty or Protégé
