WILD IDEAS

MY WILD IDEA Grand Unification of Bioinformatics Tools!

MY WILD IDEA A Query Is the same as a Workflow Is the same as an Ontology Is the same as a Hypothesis

Wild Idea is enabled by The Semantic Web: An information system where machines can automatically discover information from one source, re-interpret it, and correctly use it for a purpose that the source had not anticipated.

Semantic Automated Discovery and Integration http: //sadiframework. org Our proposed new Semantic Web Services Framework

Our Wild Research Question Imagine there is a “virtual database” containing every result from every conceivable bioinformatics experiment (whether or not they have ever been done). How do we query that database?

WORKFLOW

QUERY: SELECT images of mutations from genes in organism XXX that share homology to this gene in organism YYY

Concept: “Homologous Mutant Image”

As OWL Axioms Homologous. Mutant. Image is owl: equivalent. To { Gene Q has. Image image P Gene Q has. Sequence Q Gene R has. Sequence R Sequence Q similar. To Sequence R Gene R = “my gene of interest” }

Those axioms combine to create an OWL Class: homologous mutant images

QUERY: Retrieve owl: homologous mutant images for gene XXX

DEMO Discover members of OWL classes from distributed data that doesn’t exist…

http: //biordf. net/cardio. SHARE/ Show me patients whose creatinine level is increasing over time, along with their latest BUN and creatinine levels. PREFIX rdf: PREFIX pred: PREFIX patient: SELECT ? patient ? bun ? creat FROM WHERE { ? patient rdf: type patient: Elevated. Creatinine. Patient. ? patient pred: latest. BUN ? bun. ? patient pred: latest. Creatinine ? creat. }

Recap A SPARQL-DL Query is entered into Cardio. SHARE “Elevated. Creatinine. Patient” is defined by an OWL Ontology SHARE Interprets the OWL Class definition to learn what data needs to be discovered and/or which analyses need to be done A workflow is automatically composed and executed to retrieve and analyse that data

Recap A Reasoner is used on the resulting data to find members of the Elevated. Creatinine. Patient Ontology Class Data from those members are returned to the query. A Workflow is created to execute the remaining clauses in the query

Recap …. and… The Elevated. Creatinine. Patient Class is completely hypothetical!! It came from our imagination - we believed that those kinds of patients should exist in the dataset… …. so it was a Hypothesis!

Quod Erat Demonstrandum : -)
