Question

I have one input inference in Virtuoso Open Source, that was defined from goodrelations site —

rdfs_rule_set('http://purl.org/goodrelations/v1', 'http://purl.org/goodrelations/v1');

— that I used in query using —

define input:inference <http://purl.org/goodrelations/v1> .

Now I want to consolidate all brand which have same name, give owl:sameAs inference to it, and insert in into rule set —

rdfs_rule_set('samebrands', 'samebrands');

However, when I add more inference, Virtuoso told me I can’t add more than 1 inference to query.

How should I do it? Thank you :).

Answer 1

You have to use another pragma:

DEFINE input:same-as "yes"

See the documentation.

Another approach is to define an inference rule which contains two graphs (GR and samebrands).
