Homework #2 FAQ

1. In 1a) you ask for the titles of all papers that appear in conference proceedings, but there does not appear to be appropriate vocabulary in swpub.rdf. What should I do?

The problem should have said "Retrieve the titles of all papers that appear in the proceedings of a conference, workshop or similar event."

2. In 2), what does "rdfs:subClassOf states" mean?

It is a typo. It should read "rdfs:subClassOf statements."
