This implementation gives the flexibility of choosing word embeddings on your corpus. One has the option of choosing word Embeddings from ELMo (https://arxiv.org/pdf/1802.05365.pdf) - recently introduced by Allennlp and these word vectors are learned functions of the internal states of a deep bidirectional language model (biLM), which is pre-trained on a large text corpus. Also fastext embeddings (https://arxiv.org/pdf/1712.09405.pdf) published in LREC from Thomas Mikolov and team is available. ELMo embeddings outperformed the Fastext, Glove and Word2Vec on an average by 2~2.5% on a simple Imdb sentiment classification task (Keras Dataset).
To run it on the Imdb dataset,
run: python main.py
To run it on your data: comment out line 32-40 and uncomment 41-53
You have the option of choosing the word vector model
In config.json specify “option” as 0 – Word2vec, 1 – Gensim FastText, 2- Fasttext (FAIR), 3- ELMo
The model is very generic. You can change your model as per your requirements.
