The Text Information Extraction System or TIESNCI ITCR funded effort (U24 CA180921)
• A natural language processing (NLP) and Information Retrieval system for de-identifying, annotating, storing & retrieving pathology (and radiology) reports
• A system for indexing research resources (clinical data, biospecimens & images) with document annotations
• An GUI for querying large repository of annotated documents and obtaining resources locally, using an honest broker model
• A platform to support phenotype, images and biospecimen sharing among networks of cancer centers and other institutions

Adding Cancer Registry Data to TIESOutcomes Annotation
• Identified as a valued development target by users• We have secured additional funding from Institute
for Precision Medicine in Pittsburgh• Mike Davis and Jonathan Silverstein lead this effort• Starting with breast cancer (first publication in
review)• Immediately leveragable by existing TCRN nodes by
adding Cancer Registry data to TIES instances

Conclusions• The Text Information System (TIES) Cancer Research
Network (TCRN) is an ideal platform for coupling clinical/outcomes data to biospecimens/images
• Whole Slide Imaging (WSI) and Computational Pathology will enable NCI’s Moonshot in new ways to couple spatial analysis features to –omic data sets
• A WSI Imaging Data Sharing and Query Toolkit (TCRN) with linkages to NCI ITCR and GDC programs can assist the NCI vision for a Cancer Research Data Commons

Six Requirements of a Data Commons
• Permanent digital IDs (data and knowledge)• Permanent metadata (data describing data)• API (interface)-based access (interoperability)• Data portability (standard containers)• Data Peering (commons 1 can access commons 2)• Pay for compute (allocate computing/charging)
