There are two popular algorithms for text vector extraction: bag of words and skip-gram. The intuition behind it is that a word can be predicted by context and context can be predicted from a word. The vector size of a word is the number of neurons in the hidden layer.
The task of named entity recognition can be solved by using LSTM neural networks. The features for every word can be...
