I’ve done a lot of reading and I’ve seen that word2vec or GloVe embeddings are used in sentiment analysis tasks to retain semantic value of words. But one thing I still don’t understand is, how does a word embedding represent a sentence?
For example, for a twitter sentiment analysis project I want to classify a tweet into positive/negative/neutral.
Raw Input: The weather does not look good tonight.

Pre-processed Input before converting to vectors:  weather not good tonight

Just assume some random vectors for each of those words above.
weather: [34, 56…768] etc.
Now, how do I represent the sentence “weather not good tonight” using those word embeddings? I read somewhere that we need to average the word vectors for each of the words in the sentence and that’ll do the job.
But then how will it capture the order of the words in training? Also multiple inputs can lead to the same mean, how will the LSTM handle this?
