2
Deep Learning Tokenizer
Depling 2016 challenge requires tokenizer for any of the Universal Dependency TreeBank Build a DL tokenizer using Keras based on the approach of: Basile, Valerio and Bos, Johan and Evang, Kilian A General-Purpose Machine Learning Method for Tokenization and Sentence Boundary Detection (2013),
3
Deep Learning POS for UD
Depling 2016 challenge requires tokenizer for any of the Universal Dependency TreeBank Build a DL POS using CNN, for example a LSTM that uses word embeddings and possible charcater embeddings.
4
Deep Learning Morph Analyzer
Depling 2016 challenge requires tokenizer for any of the Universal Dependency TreeBank Build a DL morphological analyzer that copmutes the morphology of each word, using Keras and charcaher embeddings.
5
UD extensions Write scripts to extract additional relations from the analysis of UD parse trees
