====== Sequence Labeling ======
===== Semi-CRFs =====
  * Paper that introduced Semi-CRFs: [[http://www.cs.cmu.edu/~wcohen/postscript/semiCRF.pdf|Sarawagi & Cohen 2004 - Semi-Markov Conditional Random Fields for Information Extraction]]
  * [[https://arxiv.org/pdf/1604.05499.pdf|Liu et al 2016 - Exploring Segment Representations for Neural Segmentation Models]]  Shows that neural semi-CRF model benefit from representing the entire segment.

===== Miscellaneous Models =====
