Manchester Family History Advanced OWL Tutorial
Dates: 27th/28th February 2014
Time: 10am – 5pm
Location: Room G306a Jean McFarlane Building, University of Manchester.
The Bio-Health Informatics Group at The University of Manchester invites you to participate in a newly developed OWL Ontology that covers more advanced language concepts for OWL.
The overall goal for this tutorial is to introduce the more advanced language concepts for OWL. This new tutorial builds on the world-famous Manchester Pizza Tutorial, by exploring OWL concepts in greater depth, concentrating on properties, property hierarchies, property features and individuals. The topic of family history is used to take the tutee through various modelling issues and, in doing so, using many features of OWL 2 to build a Family History Knowledgebase (FHKB). The exercises involving the FHKB are designed to maximise inference about family history through use of an automated reasoner on an OWL knowledgebase (KB) containing many members of the Stevens family. The aim, therefore, is to enable people to learn advanced features of OWL 2 in a setting that involves both classes and individuals, while attempting to maximise the use of inference within the FHKB.
By the end of the tutorial you will be able to:
- Know about the separation of entities into TBox and ABox;
- Use classes and individuals in modelling;
- Write detailed class expressions;
- Assert facts about individuals;
- Use the effects of property hierarchies, property characteristics, domain/range constraints to drive inference;
- Use property characteristics and subproperty chains on inferences about individuals
- Understand and manage the consequences of the open world assumption in the TBox and ABox;
- Use nominals in class expressions;
- Appreciate some of the limits of OWL 2.
Supplementary material for the tutorial can be found at: http://owl.cs.manchester.ac.uk/publications/talks-and-tutorials/fhkbtutorial/
The cost of the course is £250 per day.

We finally completed the move of owl.cs to a new web server which is hosted by the university’s IT services team. Some things might have gotten jumbled up a little – please contact us if you come across any broken links or missing resources.

We have been providing several different OWL related web services, such as the OWL syntax converter and the ontology browser, for a few years now. It seems our current hosting solution can no longer cope with some of the larger and more complex ontologies that are uploaded, so we’ve been seeing a few server hiccups lately.
In order to deal with this problem, we’re currently in the process of moving the applications to more stable server infrastructure. In addition, we will also be providing downloads for the tools, which means that anyone wanting to modularise a large ontology can do that locally on their own machine rather than having to deal with long upload times and possible server outage.
While we’re moving the applications, this owl.cs site will also find a new home on a university server rather than our good ol’ Mac Mini, which can will improve uptime drastically. The overhaul should be completed by the end of June 2013. We will keep you updated on this.

At OWLED today, I proposed that we form a W3C Community Group. They goal is to support the activist part of the OWLED mission.
OWLED was founded in order to push OWL forward. The subtitle is Experiences (what we’ve learned) and Directions (where we want to go). We founded it because there was a bit of “OWL fatigue” at the W3C and we didn’t want OWL 1 to be the last word on OWL.
Also, at the time, the W3C wasn’t well set up to do the kind of nurturing of the infrastructure and state of deployed art we wanted to do. Formal standards aren’t the last word in any technical community: We can have rough, bottom up, effective, de facto standardization if we set up the right incentive structures.
The room was receptive so I pushed the button and we now have a proposed group! We need 4 more people with W3C accounts to push the button and then the group is ago.
As[While] I can not coerce WordPress to embed a PDF, I’ll just also provide a link to my pitch talk for the CG.
We’ll be talking about possible projects over the next 1.5 days. Feel free to drop me a line if you have an idea!
Update: We now have 6 supporters, so the group will be created! Hurray!

This two-day introductory ‘hands-on’ workshop aims to provide attendees with both the theoretical foundations and practical experience to begin building OWL ontologies using the latest version of the Protégé-OWL tools (Protege4). It is based on Manchester’s well-known “Pizza tutorial” (see http://www.co-ode.org).

The website for OWL at Manchester was looking a little creaky, so we banded together to do a complete overhaul. The first good move was to migrate to a content management system (in our case, WordPress). The second good move was to update all our WebApps to the latest OWL API. A bit of reorg and writing and you have the lovely site you see before you.
