One of the most important features of health care is to be able to follow a pa- tient?s progress over time and identify events in a temporal order. We describe initial steps in creating resources for au- tomatic temporal reasoning of Swedish medical text. As a first step, we focus on the identification of temporal expres- sions by exploiting existing resources and systems available for English. We adapt the HeidelTime system and manually eval- uate its performance on a small subset of Swedish intensive care unit documents. On this subset, the adapted version of Hei- delTime achieves a precision of 92% and a recall of 66%. We also extract the most frequent temporal expressions from a sep- arate, larger subset, and note that most ex- pressions concern parts of days or specific times. We inte...
