Word2vec-For-NER-In-Low-Resource-Languages

An efficient language-free distributionnal representation for the projection of named entities from a rich language to low-resource languages. Checkout the paper for more details

Repository description

• The data folder contains the annotations of the corpus using Brat.
• The result folder contains the results (F1, Precision, Recall) by tag for the 10 repetitions of the training. The file (results.csv)[/~https://github.com/frankl1/Word2vec-For-NER-In-Low-Resource-Languages/blob/master/results.csv] constains the averaged results for the 10 repetitions.
• The jupyter notebook brat2corpus.ipynb is used to convert brat annotation to two parallel copora corpus-ewo.txt (for the Ewondo side) and corpus-en.txt (for the English side). Each line in these file is a token with its associated annotation. Blank lines denote the end of a phrase (verse in our case). The two files are aligned such that a phrase and its translation are at the same position.
• The jupyter notebooks fnn-ne-projection-corpus-based-tf.ipynb, fnn-ne-projection-phrase-based.ipynb, and fnn-ne-projection-side-based.ipynb are the source codes used to train the model and compute performances using respectively the corpus-based term frequency, the phrase-based term frequency, and the side-based term frequency.

Reproduce the experiment

After cloning this repository, conda can be used to install all the dependencies with the command conda env create -f requirements.yml
