Jambalaya Diamond CogZ CTExplorer Summary/ Future BioPortalViz the CHISEL group, University of Victoria DIaMOND—Degree of Interest Modeling for Ontology Navigation and Development

Jambalaya Diamond CogZ CTExplorer Summary/ Future BioPortalViz the CHISEL group, University of Victoria Motivation Navigating ontologies can be tedious… –Long scrolling lists, expanding/collapsing nodes –Large number of irrelevant elements occlude relevant information Users often don’t know where to start when navigating an unfamiliar ontology –Might appreciate “worn paths” Visualizations of structure often very dense and complex –Hard to know which elements to display

Jambalaya Diamond CogZ CTExplorer Summary/ Future BioPortalViz the CHISEL group, University of Victoria DIaMOND -- Approach Applies principles of attention-reactive interfaces –Mechanism to calculate user’s degree of interest (DOI) –Dynamic display of information using the DOI Goals –Draw user’s attention to interesting elements –Reduce navigation overhead

Jambalaya Diamond CogZ CTExplorer Summary/ Future BioPortalViz the CHISEL group, University of Victoria DIaMOND (plug-in) Three levels of interest –Landmark: Hub concept Manually specified by user DOI value exceeds a threshold value –Interesting Has been interacted with such that the DOI value exceeds a (lower) threshold value –Uninteresting DOI value falls below the lower threshold value Lightweight, easily reversible focus techniques Consistent with existing, familiar views

Jambalaya Diamond CogZ CTExplorer Summary/ Future BioPortalViz the CHISEL group, University of Victoria Visualization and Jambalaya Why are visualizations important? –Ontologies can be extremely large and complex, difficult to navigate using just trees and lists –Visualizations help users understand ontologies by showing overviews and hub concepts Other visualization approaches: –OntoViz, OWLViz, TGViz, ezOWL –IsaViz: visual RDF editor –Many graph-like visualization tools! What is Jambalaya? –Protégé Plug-in for visualization –Want to integrate some of these ideas in BioPortal – which ones?

Jambalaya Diamond CogZ CTExplorer Summary/ Future BioPortalViz the CHISEL group, University of Victoria Visualizing Clinical Trials Developing new ways of visualizing clinical trials data Many different classes of users: –Clinicians, trialists, researchers Current approach for accessing trials is through RCT Presenter (Trial Bank) or ClinicalTrials.gov Currently striving for standard reporting procedures (ontology based) Visualization prototypes being developed for detailed and specific use cases

Jambalaya Diamond CogZ CTExplorer Summary/ Future BioPortalViz Issues Use cases are highly specialized – trialist, researcher Requires a lot of information (which is currently not readily available) So what can we do with data that already preexists in ClinicalTrials.gov? NCBO Council Call, Mar 4 th 2008the CHISEL group, University of Victoria

Jambalaya Diamond CogZ CTExplorer Summary/ Future BioPortalViz CTSearch Objective –To improve the experience of seeking and comparing clinical trials Research questions –How can we visualize and filter query results for large and sometimes incomplete collections of clinical trials? –How can we improve existing tags/annotations in controlled data collections to obtain better query results? (e.g. different terms used to describe the same underlying concept) Hypothesis –Seeking and comparing clinical trials can be improved by using tag clouds that afford dynamic filtering of the query results –Searching clinical trials can be improved by extending their existing annotations/tags using controlled vocabularies (e.g. UMLS) to provide better query results

Jambalaya Diamond CogZ CTExplorer Summary/ Future BioPortalViz CiteULike

Jambalaya Diamond CogZ CTExplorer Summary/ Future BioPortalViz CiteUlike Features: –The user queries one or more tags and receives a list of users and groups that are interested in those tags –Result: list of hyperlinks to articles, books or other sources of information. –A tag cloud shows related tags for the user to use in further queries –Results are based on the ‘union’ rather than the ‘intersection’ of tags. Querying for ‘Hepatocelluar carcinoma’ will bring all the resources tagged as ‘Hepatocelluar ’, ‘carcinoma’, or ‘Hepatocelluar carcinoma’. As a consequence, ‘breast-carcinoma’ will be part of the results. –The tag cloud can be filtered. For example, filtering on ‘ca’ displays: ‘cancer’, ‘classification’, ‘communication’, and ‘education’. This only filters the cloud and not the list of results.

They are contraindicated for individuals with abnormally slow heart rates or significant conduction system disease; however, the addition of a pacemaker may make beta-blocker therapy safe for these individuals. This study will evaluate the effectiveness of a pacemaker combined with beta-blocker therapy at improving survival rates and preventing subsequent heart attacks in individuals with abnormally slow heart rates who have recently experienced a heart attack.
