Blogging a Book about Bio-Ontologies

Waterloo Station Ultrawide Panoramic by Tim NugentIf you wanted to write a guide to Biomedical and Biological Ontologies [1], especially the what, why, when, how, where and who, there are at least three choices for publishing your work:

  1. Journal publishing in your favourite scientific journal.
  2. Book publishing with your favourite academic or technical publisher.
  3. Self publishing on a web blog with your favourite blogging software.

Each of these has its own unique problems:

  • The trouble with journals is that they typically don’t publish “how to” guides, although you might be able to publish some kind of review.
  • The trouble with books, and academic books in particular, is that people (and machines) often don’t read them. Also, academic books can be prohibitively expensive to buy and this can make the data inside them less visible and accessible to the widest audience. Unfortunately all that lovely knowledge gets locked up behind publishers paywalls. To add insult to injury, most academic books take a very long time to publish, often several years. By the time of printing, the content of many academic books is often very dated.
  • The trouble with blogs, they aren’t peer-reviewed in the traditional way and they tend to be written by a single person from a not very neutral point of view. Or as Dave once put it “vanity publishing for arrogant people with an inflated ego“. Ouch.

So the people behind the Ontogenesis network (Robert Stevens and Phillip Lord with funding from the EPSRC grant ref: EP/E021352/1) had an idea. Why not blog a book about Ontology? As a publishing experiment – it might just work by combining the merits of books and blogs together in order to overcome their shortcomings. This will involve getting a small group of about twenty people (mostly bio-ontologists) together, and writing about what an ontology is, why you would want to a biomedical ontology, how to build one and so on. We will be doing some of the peer-review online too.

As part of an ongoing experiment, we are posting all this information on a blog called http://ontogenesis.knowledgeblog.org if you’d like to follow, subscribe to the feed and read the manifesto.

XML Summer School, Oxford

XML Summer School, Oxford, U.K.After a brief absence, it is good to see the XML Summer School is back again this September (20th-25th) at St. Edmund Hall, Oxford. This is  “a unique event for everyone using, designing or implementing solutions using XML and related technologies.” I’ve been both a delegate and a speaker here over the years; back in 2005, with Nick Drummond we presented the Protégé and OWL tutorial which was good fun.  So here is what I.M.H.O. makes the XML summer school worth a look: (more…)

Congratulations Matthew Horridge!

George Best Genius by sahmeepeeSo, congratulations are due to Matthew Horridge, Bijan Parsia and Ulrike Sattler from The University of Manchester for winning the keenly fought best paper prize at the International Semantic Web Conference [ISWC 2008] in Karlsruhe for their paper “Laconic and Precise Justifications in OWL”. An abstract of the paper is reproduced below:

“A justification for an entailment in an OWL ontology is a minimal subset of the ontology that is sufficient for that entailment to hold. Since justifications respect the syntactic form of axioms in an ontology, they are usually neither syntactically nor semantically minimal. This paper presents two new subclasses of justifications—laconic justifications and precise justifications. Laconic justifications only consist of axioms that do not contain any superfluous “parts”. Precise justifications can be derived from laconic justifications and are characterised by the fact that they consist of flat, small axioms, which facilitate the generation of semantically minimal repairs. Formal definitions for both types of justification are presented. In contrast to previous work in this area, these definitions make it clear as to what exactly “parts of axioms” are. In order to demonstrate the practicability of computing laconic, and hence precise justifications, an algorithm is provided and results from an empirical evaluation carried out on several published ontologies are presented. The evaluation showed that laconic/precise justifications can be computed in a reasonable time for entailments in a range of ontologies that vary in size and complexity. It was found that in half of the ontologies sampled there were entailments that had more laconic/precise justifications than regular justifications. More surprisingly it was observed that for some ontologies there were fewer laconic justifications than regular justifications.”

But what does it all mean? One of the results of this research project has been an explanations plug-in for the Protégé ontology editor, see explanation in OWL at http://owl.cs.manchester.ac.uk. This helps users to understand when and why the reasoning goes all pear-shaped through better explanations than has previously been possible. So this is another step toward making building better ontologies with the Web Ontology Language (OWL) easier and less confusing. Yay!
