1 Khresmoi Towards improved medical information access Allan Hanbury Vienna University of Technology, Austria

2 Health information search today Knowledge is produced increasingly quickly Medical literature has an explosion in publications Not all clinicians have access to new information with the same speed Clinicians search for information frequently Physicians have an unmet information need for 2 of every 3 patients seen [3] PubMed search takes long (30+ minutes instead of 5 available) [4, 5] Imaging and other exams create information overload We want empowered patients but no Cyberchondria But can they access information of high quality? [6, 7, 10] 2

3 The Google problem P. López-Jornet, F. Camacho-Alonso, The quality of Internet sites providing information relating to oral cancer, Oral Oncology,

4 The PubMed problem

5 Growth [9] 5

6 Khresmoi aims to build A multi-lingual, multi-modal search and access system for biomedical information and documents Data from many sources Multi-dimensional medical images (2D, 3D, 4D) Improved search capabilities through natural language processing, information extraction, supervised and unsupervised categorization, linking text to knowledge base facts, Trustable results at a level of understanding adapted to the users 6

7 Images Language Resources Books Queries Questions Websites Information Answers Semantic Data Journals

8 Images Users Language Resources General Public Medical Doctors Queries Questions Information Answers Books Websites Radiologists Semantic Data Journals

9 Use Cases Use Case 1: Medical Information for General Public European Citizens and Medical Professionals Medical Doctors Use Case 2: Radiologists Medical Information for Radiologists

10 Use Case: Medical Information Search Information should be: Easy to find In the language of the user At the level required by the user Trustworthy and reliable End users: Health on the Net Society of Physicians in Vienna

11 (excerpt) Large-scale questionnaires and interviews are conducted with medical professionals and the general population

12 Survey Results See the results of the survey of the general public here: 12

13 Use Case: Radiology Overcome the flood of images and their complexity (Semi) automatic analysis of radiological images (CT, MRI, fmri,...) Link images to literature and past cases (anonymised) End users: Vienna Medical University University Hospitals of Geneva

16 Open Source Components GATE information extraction Mimir search ezdl user interfaces GIFT visual retrieval MOSES machine translation 16

17 Medical Databases Extremely large repositories 100s of Terabytes Zetabytes of Meta-Information Open access publishing is expanding BiomedCentral Many closed access journals are available after 12 months, also through public pressure Knowledge bases exist UMLS, MeSH, SNOMED Linked Life Data 17
