نویسندگان
چکیده
This demo presents Information Extraction from discharge letters in Bulgarian language. The Patient history section is automatically split into episodes (clauses between two temporal markers); then drugs, diagnoses and conditions are recognised within the episodes with accuracy higher than 90%. The temporal markers, which refer to absolute or relative moments of time, are identified with precision 87% and recall 68%. The direction of time for the episode starting point: backwards or forward (with respect to certain moment orienting the episode) is recognised with precision 74.4%.
