You can use the word2vec representations of various words in the input sentence to classify a given word in the sentence as an entity type or not. Take the given word along with 2 - 3 words on its left and its right. So you have a window of 5 - 7 words with the given word in between. Now you encode everyword with its word2vec representation.
