Natural language processing (NLP) is a field of computer science, artificial intelligence, and linguistics concerned with the interactions between computers and human (natural) languages. As such, NLP is related to the area of human–computer interaction. Many challenges in NLP involve natural language understanding, that is, enabling computers to derive meaning from human or natural language input, and others involve natural language generation.

How to get sentence embedding using BERT?
There is very cool tool called bert-as-service which does the job for you. It maps a sentence to a fixed length word embeddings based on the pre trained model you use. It also allows a lot of paramete …

Use embeddings to find similarity between documents
The reason I recommend USE over BERT is that, USE was trained specially for sentence similarity tasks whereas BERT, even though can be applied to any NLP task was original trained to predict words in a …

Generating synonyms or similar words from multiples word embeddings
Gensim has a built in functionality to find similar words, using Word2vec. You can train a Word2Vec model using gensim:
model = Word2Vec(sentences, size=100, window=5, min_count=5, workers=4)
You …

Do repeated sentences impact Word2Vec?
Are the sentences exactly the same, word to word? If that is the case I would suggest removing the repeated sentences because that might create a bias for the word2vec model, ie. repeating the same se …
