Hello All! 
The next NCBO Seminar Series will be held Wednesday, Sept 2, at 10am PST.
The seminar will be presented by Dr. Raimond Winslow and Stephen Granite of
the Institute for Computational Medicine. The title of the talk will be
³Progress Report: Ontology-based annotation of biomedical time­series data.²

Below is Information on how to join this week¹s online meeting and
accompanying teleconference.

Please contact me with any questions at skanel at For a schedule
of 2009 presentations through September, or for more information about the
series, please visit the Seminar Series home page:

We hope to see you there.

Title: Progress Report: Ontology-based annotation of biomedical time­series

Abstract: In a collaborating project with the NCBO, we are developing an
ontology for describing the most common form of cardiovascular data ­ the
electrocardiogram (ECG). The ontology includes the concepts needed to
describe data collection protocols (number of leads, lead placement,
instrumentation), the ECG waveform and its features in health and disease
(e.g., QRS, T waves etc; abnormalities of the ECG such as elevated ST
segment, inverted T wave, etc), data computed from the ECG (e.g., QT
interval variability, QRS width, etc), algorithms used to compute these
data, and interpretations (Minnesota codes). It has been deposited at the
NCBO (Electrocardiography Ontology, ID 1146). We will review this ontology.

We are developing this ontology so that clinical researchers can manage,
analyze, and share semantically labeled ECG data on the CardioVascular
Research Grid (CVRG). We will give a demonstration of several components of
this data management and analysis workflow. These components have been
developed using the Google Web Toolkit, with data visualization supported by
the Google Visualization API. The demonstration will include: a) a review of
the CVRG Dashboard; b) selection and upload of ECG time-series data; c) data
analysis; and d) visualization and annotation of the ECG waveform. The
latter is done by invoking Bioportal REST services from the web-interface to
retrieve concepts and definitions from the ontology. This represents
substantial progress in our effort to develop the ³electronic ECG chart
