Hello,

How do I qery individulas in my ontology, here is a description of what I would like to do (similar to SQL queries):

I have three classes (components, features, and polarity). The polarity value can be positive_polarity or negative_polarity, both are subclasses of polarity.

a_component hasFeature a_Feature

a_Feautre hasPolarity a_Polarity

I would like to list all components which have a positive_polarity value.

How can this be achieved using the DL Query tab in protege 4?

Thanks for your help in advance,

Hala
