I'm watching all of the HPI KG/rdf-related content in my free time step by step. As I am mostly working in the "NLP meets KG"-domain with a LPG-DB, I feel this is time well spent to skill up across the whole knowledge engineering domain.
I'm not sure whether I'd be a good match for sparring, but I'd definitely be interested in discussing the topic with others.
