The cultural mission of the W3C is to make the Web “available to all people, whatever their hardware, software, network infrastructure, native language, culture, geographical location, or physical or mental ability.” The way it accomplishes this is by committee, via standards documents.

Preprint: Aidan Hogan, Marcelo Arenas, Alejandro Mallea and Axel Polleres, Everything You Always Wanted to Know About Blank Nodes, Web Semantics: Science, Services and Agents on the World Wide Web, to appear, 2014.

In this paper we thoroughly cover the issue of blank nodes, which have been defined in RDF as 'existential variables'. We first introduce the theoretical precedent for existential blank nodes from first order logic and incomplete information in database theory. We then cover the different (and sometimes incompatible) treatment of blank nodes across the W3C stack of RDF-related standards. We present an empirical survey of the blank nodes present in a large sample of RDF data published on the Web (the BTC–2012 dataset), where we find that 25.7% of unique RDF terms are blank nodes, that 44.9% of documents and 66.2% of domains featured use of at least one blank node, and that aside from one Linked Data domain whose RDF data contains many "blank node cycles", the vast majority of blank nodes form tree structures that are efficient to compute simple entailment over. With respect to the RDF-merge of the full data, we show that 6.1% of blank-nodes are redundant under simple entailment. The vast majority of non-lean cases are isomorphisms resulting from multiple blank nodes with no discriminating information being given within an RDF document or documents being duplicated in multiple Web locations. Although simple entailment is NP-complete and leanness-checking is coNP-complete, in computing this latter result, we demonstrate that in practice, real-world RDF graphs are sufficiently "rich" in ground information for problematic cases to be avoided by non-naive algorithms.

UMBC is a great school for students who want to get the most out of a university education. Our suburban location between Baltimore and DC provides lots of interesting opportunities for internships, culture and fun. I have been a faculty member at UMBC for 21 years and have found working with UMBC students and colleagues to be very rewarding.

This is a nice neighborhood hardware store -- the last one in Catonsville. I had keys made here and it was inexpensive and the quality was very good. All four of the new keys work smoothly. The last time I needed keys, I got them made at Home Depot and they were more expensive and only one of the the three keys worked in my lock!
