We Present experiments on automatic segmentation of electronic Old Swedish editions into sentence-like units. Our target material is haracterized by a great variation in the type of boundaries that are marked orthographically; the extent of boundary marking; and the means of boundary marking. We begin with an exploration of boundary marking in a large; unannotated corpus of Old Swedish texts. Then we show that we are able to improve upon a simple but effective segmenting baseline; using a conditional random field model trained on a manually annotated corpus. A more valuable lesson the modelling teaches us; however; is that we need to address the boundary marking variation explicitly.
