My paper “Negation Detection in Swedish Clinical Text” has been accepted after a double blind peer-review to the 2nd Louhi Workshop on Text and Data Mining of Health Documents in L.A., June 5 2010. Later, the paper will be on my dsv-home page. A list of used Swedish negation trigger phrases can be found there already, if anyone would need to search for negations.
A part of the abstract:
NegEx, a rule-based algorithm that detects negations in English clinical text, was translated into Swedish and evaluated on clinical text written in Swedish. The NegEx algorithm detects negations through the use of trigger phrases, which indicate that a preceding or following concept is negated. A list of English trigger phrases was translated into Swedish, taking grammatical differences between the two languages into account. This translation was evaluated on sentences from Swedish health records.
