Resumé

Relation udtrykt i biomedicinske tekster kan være både meget generelle og meget specifikke. Regulatoriske relation bruges ofte i for eksempel regulatoriske netværk, og de optræder frekvent i biomedicinske tekster repræsenteret af verber. Dette arbejde fokuserer på de logiske egenskaber ved positiv og negativ regulering både som formelle relationer og deres optræden som verber i tekster. Der diskuteres desuden om der findes en svag transitiv-lignenede egenskab for relationerne. De undersøgte Korpora er hhv Medline, biomedicinske patenter og the Britisk National Corpus. Til slut diskuteres brugen af relationer til semantisk indexering i information retrieval.
