The Bio-Health Informatics Group Andy Brass – Robert Stevens –

What is Bio-health Informatics? Biology, medicine and health care produce lots of data They produce very complex data They produce volatile data And it’s a bit of a mess too Bio-health informatics is all about managing and analysing those data Data management and description (ontologies, linked data, integration) Data science – innovative methods for making the data work…

What is an ontology? The number “7” isn’t much good to us… “7 cm” tells us it’s a length, but not what it’s a length of… “7 cm tail which is part of a mouse” tells us a whole lot more Descriptions of the semantics of a domain in the form of an ontology We write these ontologies in the Web Ontology Language (OWL) Building, using, evaluating these ontologies is of research interest

Evaluating an emotion ontology Can members of the audience at the International Conference on Biomedical Ontology articulate their emotional response to a talk using the emotion ontology? For each talk, audience members record their emotions and ease of articulation using tags We analyse the data for: –Whether the tags were adequate –Strength of emotional response –Effects of talk, time of day –Tags that are missing anxiety anger contempt disgust surprise grief interest fear pleasure jealousy compassion hate disappointment irritation moral disgust

Making kidney and urinary pathway data useful

What if…? An ontology is a complex system of axioms An automated reasoner draws inferences from the axioms in the ontology “What if…” I add this axiom? Investigating the authoring tasks, for an ontology How do we help authors to explore the effects of the axioms we add?
