Abstract:
Recently, the i2b2 Center for Center for Biomedical Computing at the
University of Albany organised an natural language processing shared
task that focused on obesity and its co-morbidities. The data for the
task consisted of discharge summaries for patients, a discharge
summary is a textual narrative, semi-structured patient record of all
the care delivered to a patient during their stay. Each of the
discharge summaries was annotated at the document level with
information regarding whether the patient was suffering from obesity
or any of its co-morbidities. The goal of the challenge was to develop
classification systems that could, given a discharge summary, return a
diagnosis of what morbidities the patient was suffering from. This
talk will describes the approach to the challenge adopted by the DIT
AIGroup ( http:www.comp.dit.ie/aigroup ). Based on experimental
results a system was developed which used knowledge-light text
classification using negation labelling and the UMLS medical lexicon.
