SWAT4LS: The Semantic Web in Scotland

James Clerk MaxwellLast Friday, the UK National e-Science Centre in Edinburgh hosted a workhop, Semantic Web Applications and Tools for the Life Sciences (see SWAT4LS.org for the full details). Here are some incomplete and abbreviated notes from the workshop where there were some interesting people, paperware and software.

People and Paperware

  • Nadia Anwar presented a paper on Semantic Data Integration for Francisella tularensi Proteomic and Genomic Data. This described experiences of developing a system for converting proteomics data in Excel to RDF, and what the benefits were.
  • Heiko Dietze presented a paper on GoWeb: A semantic search engine for the life science web. Have a look at GoWeb query for the hexokinase enzyme for an example of the currently capability of GoWeb.
  • Simon Jupp presented a paper on Knowledge Representation for Web Navigation which described why the Simple Knowledge Organisation System (SKOS) is sometimes a more suitable language for modelling knowledge than OWL and RDF.

Around 70 people registered to attend SWAT4LS in total, many familiar names and faces, plus some new people I’ve never met before: (more…)

Blogging Professors: Douglas Kell at the BBSRC

Filed under: web of science — Duncan @ 12:53 pm
Tags: ,

Biotechnology and Biological Sciences Research CouncilTo add to the growing list of big boffins with blogs, Professor Douglas Kell has launched his BBSRC hosted blog. So has blogging finally gone from an innovative underground movement to grown-up mainstream everyday technology, as recently suggested in The Economist? How many more senior scientists might we see blogging in the future? Take a look at blogs.bbsrc.ac.uk to find out..

I asked Doug if he would consider blogging, for the Science blogging challenge posed by Nature Publishing Group, so thanks Doug for being open minded, you’ve also been entered for the Open Laboratory 2008 competition too. It will be interesting to see what the result of this experimental project will be…

Embracing Registries of Web Services

Filed under: informatics, web of science — Duncan @ 2:00 pm

Embracing by tanakwhoIf you travel back in time, to around 2002, it isn’t difficult to find people claiming that Web services were going to be the new silver bullet technology to create world peace, eradicate global poverty and finally make some sense of all the data produced by the human genome project. Over hyped? Just a bit. One of the many reasons none of these things happened, is it turned out to be much harder than anticipated to build centralised registries, where people could go to find Web services to perform a given task. Can service registries ever be built? Critics like Tim Bray at Sun Microsystems for example, have suggested that (quote) “registries are a fantasy”, but some already exist and there are more in the pipeline. This article briefly introduces some of them: Seekda, BioMOBY, the Embrace service registry and the Biocatalogue project. (more…)

Science blog meme: Why do we blog?

Filed under: informatics — Duncan @ 10:37 am
Tags: , ,

Keep Calm and Carry On via AJC1I have been virally infected by Martin Fenner’s “why do we blog” meme.

1. What is your blog about?

Science and technology, especially bioinformatics, systems biology and the Web. It is a personal laboratory notebook-cum-diary, with a few facts and many opinions that would be difficult to publish conventionally [1].

2. What will you never write about?

Banal personal trivia (”I went shopping today”), confidential work, collaborative projects before they have been published. If in doubt, I try to ask people, “is it OK if I blog this?”

3. Have you ever considered leaving science?

Already did, I left science after my undergraduate degree to work in industry, but came back after six years to do a PhD. Can’t see myself leaving again. I don’t think Science ever really leaves you, once a scientist, always a scientist.

4. What would you do instead?

Tend olive trees in Greece. Maybe do some olive tree systems biology!

5. What do you think will science blogging be like in 5 years?

Pretty much the same as it is now I reckon, maybe more senior people will start blogging, see big boffins with blogs.

6. What is the most extraordinary thing that happened to you because of blogging?

I’m pretty sure blogging was a significant factor in being invited to Science Foo Camp (scifoo)


7. Did you write a blog post or comment you later regretted?

Non, je ne regrette rien. Some of the posts about semantic web and molecular biology I might come to regret in the future though, but life is too short. There is an ever present temptation to write controversial blog posts (that might be regretted later) to get more visitors to your blog. Sometimes I can’t resist. Also, there is no safety net of peer-review, so you can make mistakes very quickly, even faster than by drinking tequila. I often wonder what prospective employers and/or funding bodies would make of it all - by the time I find out, it might be too late :)

8. When did you first learn about science blogging?

Via nodalpoint which is run by Greg Tyrelle.

9. What do your colleagues at work say about your blogging?

So far, there have been five basic responses to my blog among colleagues.

a) Great idea, carry on (see picture, top right). Can you blog this for me?
b) Bad idea, why do you waste so much time blogging? When are you going to do some “real” work?
c) Teasing: “I’m drinking a coffee, are you blogging this?”
d) Head-in-the-sand, no acknowledgment, denial, look the other way.
e) Ignorance is bliss. What is a blog? Do you have one of those interweb things on your computer?

Defrosting the Digital Library

Bibliographic Tools for the Next Generation Web

Sunset Ice Sculptures by Mark K.We started writing this paper [1] over a year ago, so it’s great to see it finally published today. Here is the abstract:

“Many scientists now manage the bulk of their bibliographic information electronically, thereby organizing their publications and citation material from digital libraries. However, a library has been described as “thought in cold storage,” and unfortunately many digital libraries can be cold, impersonal, isolated, and inaccessible places. In this Review, we discuss the current chilly state of digital libraries for the computational biologist, including PubMed, IEEE Xplore, the ACM digital library, ISI Web of Knowledge, Scopus, Citeseer, arXiv, DBLP, and Google Scholar. We illustrate the current process of using these libraries with a typical workflow, and highlight problems with managing data and metadata using URIs. We then examine a range of new applications such as Zotero, Mendeley, Mekentosj Papers, MyNCBI, CiteULike, Connotea, and HubMed that exploit the Web to make these digital libraries more personal, sociable, integrated, and accessible places. We conclude with how these applications may begin to help achieve a digital defrost, and discuss some of the issues that will help or hinder this in terms of making libraries on the Web warmer places in the future, becoming resources that are considerably more useful to both humans and machines.”

Biotechnology and Biological Sciences Research CouncilThanks to Kevin Emamy, Richard Cameron, Martin Flack, and Ian Mulvany for answering questions on the CiteULike and Connotea mailing lists; and Greg Tyrelle for ongoing discussion about metadata and the semantic Web nodalpoint.org. Also thanks to Timo Hannay and Tim O’Reilly for an invitation to scifoo, where some of the issues described in this publication were discussed. Last but not least, thanks to Douglas Kell and Steve Pettifer for helping me write it and the BBSRC for funding it (grant code BB/E004431/1 REFINE project). We hope it is a useful review, and that you enjoy reading it as much as we enjoyed writing it.

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!

OWL Experiences and Directions (OWLED) 2008

Great Grey Owl by Brian ScottThe Web Ontology Language (OWL) is a language for creating ontologies on the Web. It does exactly what it says on the tin. But what is an ontology? One way to think of it is as a better way of storing data and knowledge. Instead of just capturing and describing data in a databases, ontology languages like OWL provide ways to capture and describe knowledge in a knowledge base. Ontologies can allow more intelligent querying, integration and understanding of data than is possible using a plain old relational database.

Since 2003 developers and users of the Web Ontology Language, abbreviated to OWL (not WOL), have been gathering at a two-day workshop called OWLED (OWL Experiences and Directions). This year the workshop is in Karlsruhe in Germany. The full list of accepted papers is available, as with previous years, this years workshop has a distinctly biological flavour to the proceedings: (more…)

PNAS envy?

Lincoln with Stars & Stripes by tanakawhoThe United States National Academy of Sciences (NAS) is an “honorific society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare”. Set up by none other than Abraham Lincoln himself, the academy publishes a prestigious scientific journal, called the Proceedings of the National Academy of Sciences, better known as just “PNAS” and available at www.pnas.org. This publication is  part of a supposedly elite club of high-profile journals - Nature, Science and PNAS (NSPNAS) - that many scientists from all around the world, strive to publish in. Now, there are those that think the world would be a better place if we concentrated on what scientists have to say, rather than where they say it. But currently, life doesn’t always work that way. Better journals, usually tend to have better reviewers and these are often the most important places to publish results. (more…)

Open Access Day: Why It Matters

Open Access Day 14th October 2008Today, Tuesday the 14th of October 2008, is Open Access Day. Like many others, this blog post is joining in by describing why Open Access matters - from a personal point of view. According to the wikipedia article Open Access (OA) is “free, immediate, permanent, full-text, online access, for any user, web-wide, to digital scientific and scholarly material, primarily research articles published in peer-reviewed journals. OA means that any individual user, anywhere, who has access to the Internet, may link, read, download, store, print-off, use, and data-mine the digital content of that article. An OA article usually has limited copyright and licensing restrictions.” What does all this mean and why does it matter? Well, in four question-and-answer points, here goes… (more…)
