Segmentation of science and technology (S&T) literature is a basic step in S&T documents information processing. This paper takes biomedical literatures as the instances and studies domain adaptation technology in segmentation of S&T literatures. Then it takes some methods such as dictionary features, domain character features, sub-word tagging and low quality in-domain training corpus based on dictionary-based segmentation to adapt Chinese segmentation method based on sequence labeling in journalism filed to S&T filed and achieves the significant improvement. It finds that how to exploit domain specific features with domain knowledge plays an important role in improving the segmentation quality of S&T literatures.
