NCRI UK National Cancer Research Institute Partnership of more than 20 public and private organizations Goal: Promote data sharing Data standards Forming alliances Developing an IT infrastructure Willingness to share Ability to share Cultural Change through Community Alliances Help to build a Cancer Informatics Platform via ONIX Modified from A. Hogg, NCRI

NCRI ONIX Oncology Information Exchange Released July 2009 Adding connected resources Modified from A. Hogg, NCRI Built using caBIG technology caCORE, Introduce, caGrid, LexEVS

ONIX and Vocabularies ONIX uses the LexEVS 5.0 terminology server NCI-Thesaurus Gene Ontology ONIX QuickSearch Federated queries across databases Find and add synonyms, spelling variants, preferred terms to queries Working toward creation of a federated vocabulary service Encourage publication of content Exploring authoring tools (e.g., LexWiki)

i2b2 Informatics for Integrating Biology and the Bedside NIH-funded National Center for Biomedical Computing Building a "scalable computational framework to address the bottleneck limiting the translation of genomic findings and hypotheses in model systems or organisms relevant to human health" New computational paradigms and methodologies Focus on three polygenic diseases (airway disease, hypertension, type 2 diabetes mellitus) and one monogenic model characterized by polygenic modifiers (Huntington’s Disease) Cells compose the hive Interoperable services with web interfaces Minimal computable semantics Deep semantics are defined by each cell and interpreted by the user

i2b2 Database Concept table design Data is loaded into a static data model Each "name" is a hierarchical string of concepts Modified from R. Wynden, Ontology Mapper

Ontology Mapper The Ontology Mapper Cell is a general purpose instance mapper Translates messy local data into one or more standard formats (ontologies) Translates local semantics to standard semantics (e.g., NCI-T) Local instances of LexEVS E.g., from a given cell in the hive to ISO data model caGrid cell exposes i2b2 resources on caGrid Maps are created in a Protégé Prompt plug-in and can be shared over HL7 CTS II both as open source or as commercially sold assets Can be loaded into caDSR Ontology Mapper shifts resources from IT (application building) to handling user requests for data access via dynamically constructed views of data (Data Repository Analysts) Mapped on demand

Tool Releases NCI Protégé 1.4 Release scheduled for October 2009 Last major release of the NCIEditTab Protégé plug-in Enhancements Refactoring for maintenance and performance Added ability to use negation ("NOT") in queries Added Lucene Match, Property Present, and Property Absent search types Significantly extended flexibility of lexical queries Export to spreadsheet includes super classes

Tool Releases LexEVS 5.1 Release scheduled for December 2009 Enhancements Support for content in RRF (e.g., NCI Meta-Thesauraus) Value domain support (pick lists) Query performance and behavior enhancements Improved loader framework (modularity) BDA (Build and Deployment Automation) support for deployment to remote servers

LexEVS 5.0 Boot Camp November 17-19, 2009 NCI CBIIT Training Facility (Rockville, MD) Target audience Intermediate to advanced LexEVS users Users migrating from EVS 3.x or LexEVS 4.x Goals Understand new components of the LexGrid model Utilize the API in local, distributed, and grid environments Install and configure LexEVS 5.0 (all 3 environments) Learn about the extensions, loaders, and convenience methods Learn how to use the GUI See the VKC wiki for more information

LexAjax Develop an Ajax interface for LexEVS Project goals Develop an Ajax based service based on the LexEVS API and LexGrid data model that can support a variety of web based auto completion, dropdown forms, etc. Develop a basic set of graphics widgets. Integrate the graphics widget into LexWiki to provide a set of tools that can be used with Semantic Forms and other wiki based terminology access tools. Benefits include Further integration of semantic infrastructure Enhanced capability to serve terminology content to web applications Release scheduled for December 2009

Special Projects Terminology Index Expanding the list of terminologies Soliciting use cases and experiences Standards Organizations Coordinating with VCDE effort Terminology focus (e.g., HL7 CTS2) NCI Semantic Infrastructure Requirements Support for the Concept of Operations
