Definite NPs and background knowledge in medical text

Abstract [en]

An authentical medical corpus is investigated with the aim of concretizing the background knowledge required for understanding the texts. It is assumed that the discourse situation systematically flavours the background knowledge engaged in the comprehension process. An accordingly tuned and formalised knowledge fragment is referred to as a background profile of the discourse. Some aspects of the background profile of the corpus are identified via a study of coreference relations (with lexical definite NPs as the primary clues). It is found that they range from purely structural repetition to complicated semantic relationships involving substantial insights into the medical reality. It is demonstrated how the concrete discourse situation should influence the design and contents of the background profile as regards word definitions, the interpretation of traditional semantic relations, the statement of encyclopaedic (medical) knowledge, the structuring of the medical procedures for the purpose of focus definition, and the determination of a medical relevance concept.
