much of which is
unstructured

Creating a Corpus of Knowledge for Cancer Care
Ingestion of NCCN guidelines for breast cancer and lung cancer:
‒ Roughly 500,000 unique combinations of breast cancer patient attributes.
‒ Roughly 50,000 unique combinations of lung cancer patient attributes.
Over 600,000 pieces of evidence ingested, from 42 different publications/publishers, including:
‒ The Breast Journal, National Comprehensive Cancer Network (Clinical Practice
Guidelines, Drug and Biologics compendium, et al.), American Journal Of Hematology,
Annals Of Neurology, CA: A Cancer Journal For Clinicians, Cancer Journal, Cochrane,
EBSCO, Hematological Oncology, Hepatology, International Journal Of Cancer, Journal
Of Gene Medicine, Journal of Clinical Oncology, Journal of Oncology Practice,
Massachusetts Medical Society Journal Watch, Massachusetts Medical Society New
England Journal Of Medicine, Merck, Nephrology, UptoDate, Clinical Lung Cancer,
Current Problems in Cancer, Cancer Treatment Reviews, Elsevier's Monographs in
Cancer (multiple), Clinical Breast Cancer, European Journal of Cancer, Lung Cancer
(the journal).

Building a German Healthcare Domain knowledge in IBM Content Analytics
• Including first catalogues and rules for identification of diagnoses,
procedures, medication, anatomy
• Coding suggestions (ICD-10, MEL), first relationships and hierarchies
• Identification of sections inside the documents (anamnesis, discharge
diagnoses, recommended medication etc.)
• Normalization of selected information (dates, dosage, sizes etc.)
• Basic identification of Negations

Herr Mustermann wurde nach akutem Koronarsyndrom aus dem Klinikum XX zur
Koronarangiografie übernommen. Die Untersuchung ergab eine koronare
Dreigefäßerkrankung. Zudem fiel eine höhergradige, symptomatische
Mitralinsuffizienz auf, so dass der Patient am 10.Jän.2013 sich einer
Bypass-Versorgung mit Mitralklappenersatz unterziehen wird.

IBM Content Analytics can be used in different settings in Healthcare
• Better overview for physicians in electronic health records / EMR Systems
(real-time)‒ Patient Summary
‒ Semantic Search
• Medical analytics based on patient records (retrospective)‒ Quality-Management
‒ Medical analysis of HIS/EMR documents or even archived documents
• Administrative analytics‒ Analyze DRG reimbursement based on clinical documents
‒ Analyze any other free text information like patient satisfaction
• Research analytics ‒ University hospitals, Pharma / Life Sciences, Payer
‒ Content Analytics, Predictive Analytics and Patient Similarity Analytics
• Literature search (physician, patient, researcher)‒ Literature analysis, Combination of unstructured data and literature
‒ Find relevant literature that fits to unstructured information
