Abstract:
Much information about patients is stored in free text. Hence, the computerized processing
of medical language data has been a well-known goal of medical informatics resulting
in different paradigms. In Gottingen, a Medical Text Analysis System for German (abbr.
MediTAS) has been under development for some time, trying to combine and to extend
these paradigms. This article concentrates on the automated syntax analysis of German
medical utterances. The investigated text material consists of 8,790 distinct utterances
extracted from the summary sections of about 18,400 cytopathological findings reports.
The parsing is based upon a new approach called Left-Associative Grammar (LAG) developed
by Hausser. By extending considerably the LAG approach, most of the grammatical constructions
occurring in the text material could be covered.
