@KolyaIvankov: look, we're trying to find out whether changing shape of the placeholder will just work. for that we need to know whether the variables using this placeholder also have minibatch dimension. if not, then we can proceed 将不同长度的句子用BERT预训练模型编码,映射到一个固定长度的向量上:Mapping a variable-length sentence to a fixed-length vector using pretrained BERT model have tried but the results are not good enough comparing with the gensim word2vec
where ${wordvec_dir} is the target directory to store the word vector files, and should be the same as where the environment variable WORDVEC_DIR is pointed to..

Word2vec is a word embedding process. The concept is relatively simple: sentence by sentence, it loops through the corpus, and fits a model that predicts words based on neighbouring words from a pre-defined sized window.
There are two main ways to obtain word embeddings: Learn it from scratch: We specify a neural network architecture and learn the word embeddings jointly with the main task at our hand (e.g. sentiment classification). i.e. we would start off with some random word embeddings, and it would update itself along with the word embeddings.

We use the following heuristics for the Word2vec experiment: All num- bers longer than a single digit are converted into a ‘#’ (e.g., 24 → ##) then prefixed, suffixed and infixed punctuation is recursively removed from each token that does not match an entry in the model’s lexicon.

It uses word2vec vector embeddings of words. Word2vec is a two-layer neural net that processes text. Its input is a text corpus and its output is a set of vectors: feature vectors for words in that corpus. While word2vec is not a deep neural network, it turns text into a numerical form that deep nets can understand. Figure 1: word2vec

word2vec is a group of Deep Learning models developed by Google with the aim of capturing the context of words while at the same time proposing a very efficient way of preprocessing raw text data. This model takes as input a large corpus of documents like tweets or news articles and generates a vector space of typically several hundred dimensions.

Jul 11, 2016 · SAT2Vec: Word2Vec Versus SAT Analogies July 11, 2016. Word embeddings, like Word2Vec and GloVe, have proved to be a powerful way of representing text for machine learning algorithms. The idea behind these methods is relatively simple: words that are close to each other in the training text should be close to each other in the vector space.
