 ## Better Modeling of Incomplete Annotation for Named Entity Recognition 
 
 This repository implements an LSTM-CRF model for named entity recognition. The model is same as the one by [Lample et al., (2016)](http://www.anthology.aclweb.org/N/N16/N16-1030.pdf) except we do not have the last `tanh` layer after the BiLSTM.
+The code provided is used for the paper "[Better Modeling of Incomplete Annotation for Named Entity Recognition](http://www.statnlp.org/research/ie/zhanming19naacl-ner.pdf)" published in 2019 Annual Conference of the North American Chapter of the Association for Computational Linguistics (*NAACL*).
+
+__NOTE: I'm planning to implement a (more user-friendly) pytorch version of this project. Let me know in the issue if you are interested in that.__

 Change the `model_type` to `our_soft` to run our soft variant.

+### Future Work
+Working on a Neural Partial CRF Suite with PyTorch, which should be a neural network version of the [partial-CRF suite](https://github.com/Oneplus/partial-crfsuite).
