Title: Comprehensive Self-service Life Science Data Federation with SADI semantic Web services and HYDRA.

Presenter: Dr. Alexandre Riazanov, Chief Technical Officer, IPSNP Computing Inc, Canada


Life sciences have accumulated and continue producing enormous amounts of electronic data, both experimental and analytically inferred, and healthcare organisations also possess large amounts of information-rich clinical data. It is widely believed that analysis of this data may facilitate new life science discoveries and help to improve clinical practices rationally, but currently the data is severely underused due to the lack of adequate tooling.
Many questions relevant to life scientists and clinicians can only be answered using data from multiple sources, which are often geographically distributed, autonomous and highly heterogeneous, including various
* in-house databases, online databases maintained by different organisations;
* spreadmarts accumulated by disparate research groups;
* nomenclatures, controlled vocabularies, ontologies;
* Web sites, scientific publications, patents, clinical abstracts.

Querying such fragmented data requires some form of data federation. It is also desirable that the querying be self-service, so that non-technical users -- biologists, clinicians, students, etc. -- can access the data without help from IT personnel.

In my talk, I will present a solution to this comprehensive self-service data federation problem, based on the use of the SADI framework and IPSNP's querying tools for SADI. SADI is a novel semantic Web service platform that facilitates creation of RESTful Web services with complete semantic descriptions of their functionality. This unique property enables smart query engines, like IPSNP's HYDRA, to automatically find and orchestrate SADI services needed for execution of SPARQL queries. IPSNP Computing also develops an intelligent GUI to make query composition accessible to biologists and clinicians.

The first half of my talk will be a moderately technical overview of SADI principles and capabilities, and IPSNP tools, including an overview of Life Science case studies. It is designed to be accessible to the general Computer Science and Software Engineering audience. Time permitting, the second half of the talk will be more technical, although relatively self-contained, and tailored to people interested in practical aspects of SADI: I will go step-by-step through an example of SADI service creation, deployment and use.
